The Risks of Doing Sandblasting without Professional Guidance

Posted on: December 3rd, 2016 by byersbushblog No Comments

Not many people know it, but sandblasting is one of the most dangerous jobs around.  Why?  Primarily because sandblasters are exposed to high levels of silica that are present in the air, which can be quite life threatening.  This is especially true when safety precautions are not in place.

This is the reason why it is highly suggested that sandblasting be left to the professionals.  There is also the issue of possible faulty equipment that can result in critical physical injuries.  What other dangers does sandblasting pose to the untrained person?

Lung Disease

Exposure or inhalation of crystallized silica is toxic because it can result in a lung condition known as silicosis.  This happens when the rocks are damaged, releasing harmful silica into the air.  The silica particles are so small that they are virtually invisible.  Silicosis is also often referred to as sandblaster’s disease.

Why is it so dangerous?  Because silicosis is considered incurable and untreatable.  A person with this condition will have his lungs filled with fibrous tissue.  Even if the person is no longer exposed to silica particles, there is no way of reversing the condition.  Those working in sandblasting jobs have the highest exposure risk to silicosis, which can be aggravated by poor ventilation in the work environment.

The best hope for survival is the early detection of silicosis.  Additional or continued exposure though will result in the development of complications that will further put the person’s health at risk.

Dust in the Environment

We are not talking about the ordinary dust that we encounter at home.  When it comes to the sandblasting work environment, there are primarily 2 types of dusts that people should be concerned about:

  1. Airborne Dust – these are hazardous dusts identified with sandblasting operation. The concentration and size of the dust particles become determinants of the level of danger that it poses.  Larger dusts can be considered as mere nuisances because they can be filtered by the nose and throat.  However, smaller particles, particularly those that are 10 microns or smaller can pass through the filtering system of the lungs and go deep into our respiratory system where numerous damage can happen.
  1. Metal Dust – these dusts are produced from the blasting of metals like cadmium, lead, or manganese, which are very toxic once inhaled. Paints that are lead base can also pose such danger.  The need for special handling procedures is the reason why sandblasting should only be done by trained personnel, especially when lead is involved.

Filtered Air Systems

Why should sandblasting be done only by professionals?  Only professionals understand the importance of having the proper air filtration system in the work environment.  This means you simply cannot do blasting operation in your garage.  The air filtration system is an additional safeguard to protect workers from silicosis.

So the untrained person does not understand or will not realize when an air filtration system breaks down or how silica exposure can be avoided.  Professionals have to do routine air tests in the sandblasting work environment to make sure that the amount of silica remains in safe levels.  If the tests are not done, there is no way of ensuring the safety of workers.

It is not enough that you are wearing protective gear when sandblasting.  Clean compressed air from a filtration system must be present.  Any damage or leak in the filtration’s air supply will put workers at risk of silicosis.  Professionals understand likewise the need to keep wearing their helmets in the work area at all times.  Only proper training will equip workers with the knowledge that the filters are clean and in good working order.

Bottom line is that the only safe way to protect yourself from potential respiratory system damage and possible lung disease is to hire professionals to do the sandblasting for you.

Restoring Pool Chairs from Harsh Condition

Posted on: December 1st, 2016 by byersbushblog No Comments

Eventually, pool chairs will become faded, sunburned, and dried out because of exposure to the elements.  Replacing them with a new set will always be an option, but, it can be quite an expensive solution.  It can also be a wasteful solution especially if your pool chairs are not yet worn down or full of rust.

Can you imagine throwing out your pool chairs just because of chipped paint, broken straps, and a few rusty parts?  Is there a better and cost-effective solution?  Yes there is!  Read on.

Restoration

This is a process that can give your aging pool chairs a completely new look.  The great news is that it does not necessarily have to look the way it was before.  Yes, you can change the look of your pool chairs to make it appear as though you bought a new set; for a fraction of the price.

What does this process involve?  There are a few steps that have to be done to get your pool chairs looking like new again, and these are:

  1. Removing the old paint – this process removes the old paint coating your pool chairs to expose the actual status underneath. This also gives the chance to clean up and prepare the pool chairs for restoration.  You cannot properly restore the furniture to look like new if you do not get rid of the old paint coating.
  1. Sandblasting – this is the best way to remove any existing finish on the pool chairs to make sure that the metal does not get damaged. Usually, an aluminum oxide sand is used for the sandblasting process to get rid of corrosion.  This process is necessary to prepare the frame of the pool chairs for powder coating by completely removing the remaining old paint, corrosion, rust, and other similar contaminants.  The pool chairs can also be treated with an additional coating that can help prevent future rusts from occurring.
  1. Phosphate wash – sometimes called as phosphating, this process makes use of acid to attack the metal and redeposit a metal substrate material together with the phosphate. The result is that the pool chairs have a surface that becomes adherent to its base metal.  Why is this important?  It allows for improved corrosion resistance and allows the powder coating to stick better to the pool chairs.  This ensures that it gets a great coating base to extend the useable life of the pool chairs.  This pre-treatment process is essential but commonly overlooked especially by services that lack experience and training.
  1. Powder coating –this process makes use of a combination of additives and resins, which are melted, mixed, cooled, and then grinded to powder until a talcum-like consistency is reached. Using electrostatic techniques, the combination is applied to the pool chairs, which are then baked in an oven until a full cure is achieved.  The result is a strong finish that even a hammer cannot crack!  Best of all, the finish is shiny, sparkly, and of high quality that can last for years.
  1. Re-strapping – this is the last step to ensuring that your pool chairs look brand new. The original size and style can be followed or if you prefer, a newer look can be used for the straps.  Professionals can do this work flawlessly without leaving a hint that your pool chairs have been restored.  With the right restorer, you can have a wide range of options in terms of colors, design, and styles.

Upon completing the process of restoring your pool chairs, they should look as good as (or even better) than new.  With the right choice of service provider like Byers Bush Powder Coating Inc., you can preserve the look of your restored pool chairs for the next 10 years.

Protecting Your Valuable Bicycle with Powder Coating

Posted on: November 29th, 2016 by byersbushblog No Comments

There are different reasons why people ride bicycles and there are an equal number of reasons why bicycle frames can get damaged.  This is especially true if you use your bicycle more than just for recreational purposes.  What can you do to protect your bicycle against these multiple threats?

The Threats

Just like anything else, bicycles are not intended to last forever.  Eventually, it would have to give in, but, this does not mean that you should accept a shortened service life.  There are several threats that you should consider that can contribute to the breakdown of your bicycle like pollution, rays of the sun, constant use, and negative environmental factors among others.

All of these will result in a faded or chipped finish that can ruin the overall look of your bicycle over time.  Will covering up your bicycle or putting it in the shade while not in use protect it from the harmful effects of intense sunlight?  Is there a way to prevent paint peeling, deterioration or dulling of the finish, of scratches?  Aside from wrapping up your bicycle and never using it again, there is another solution to consider.

Powder Coating Protection

Currently there are 3 ways to get a bicycle frame finish, brush, spray, or powder coat.  Why choose powder coat over the 2 options?

During the past decades, powder coating has proven to be the best option in getting the best finish possible on metals like bicycle frames.  The process makes use of electrostatic charge to attract powder particles to the surface of the bicycle frame.  How does the process go after all the preparation work is completed?

  • A flour-like powder is sprayed on the surface of the bicycle frame to be coated.
  • The bicycle frame is then subjected to oven-baking to melt the powder to create a smooth coating. Normally the oven will run with temperature around 250 degrees.  The oven used should be large enough to house the bicycle frame.  A tandem bicycle frame would require a bigger powder coating oven.
  • The result is a strong, durable, smooth, and glittery coating for your bicycle frame.

Why is it necessary to bring your bicycle frame to an excellent powder coating provider?  First off, achieving such a beautiful, high quality finish becomes easier.  Second, only experienced powder coaters will know how to deal with issues of grease and block oil liquefying and running out of the frame during baking.  When done wrong, these materials can ruin the finish of your bicycle frame.

You have to be aware that powder coating can either be thermoplastic or thermosetting.  This means that it can melt when reheated or harden after permanent baking, respectively.  Thermoplastic powder coating would be used if you want to simply touch up the look of your bicycle, allowing seamless blending with the surrounding areas.

Recoloring can be done either by light sanding followed by solvent-based spray painting, or using additional powder coat.  The latter requires the original coat to be completely removed before a new powder coat is applied.

Advantages for Bicycles

Are there any advantages to protecting bicycle with powder coating?  Actually there is.  The surface that is protected with powder coating becomes more resistant to impact and scratches, somewhat a benefit if you subject your bicycle to extreme conditions.

Powder coating is also resistant to many chemicals, which means it is an added layer of protection for your bicycle.  If you have a tight budget, you will be glad to know that this process is comparatively lower even if you want to recycle colors.  Compared to paint, powder coating does not pose threats to the environment.

Since special equipment is required to properly do powder coating, you would need a professional provider to carry it out.  Byers Bush Powder Coating Inc. makes use of professional coating techniques and boasts of excellent turnaround times so that you can get your bicycle back in virtually no time at all.

Contact Byers Bush today to start protecting your valuable bicycle with powder coating and ride your bicycle wherever you want with no worries about extreme condition that cause corrosion.

Knowing AAMA Rating in Powder Coating Application

Posted on: November 27th, 2016 by byersbushblog No Comments

If you are not part of the powder coating industry you wouldn’t be aware that there are differences in the quality of the coats.  But then again, if you are not in the powder coating business, would these differences even matter to you?  Actually it should.

For example, you must be aware that powder coats are designed for specific applications so you cannot use once formulated for metal furniture and appliances to coat railings.  How are the quality of the powder coats determined?  Who makes the determination?

The AAMA

When it comes to the determination of the quality of powder coats, the American Architectural Manufacturers Association (AAMA) makes use of a rating system to distinguish between different coating materials.  Normally, powder coat ratings can fall under 3 categories based on the quality of the finish.

This is determined by the AAMA following demanding testing procedures to uncover the durability of the powder coats and how well they would look after some time.  Factors like color retention, dried paint thickness, and gloss retention are some of the factors taken into consideration.  Accelerated testing procedure is also used to determine if the powder coat can hold up against the impact of humidity and salt spray.  The levels of acceptability are also defined by the AAMA.

AAMA Categories

Based on the determination of the AAMA, powder coatings will be categorized as one of the following:

  • 2630 Specification

Given to basic powder coating types, it identifies materials ideal for coating building interiors like tiles or window sills.  These types of powder coatings will not be able to take the punishment of the outdoors for any substantial amount of time.  However, it can protect significantly better than paint against wear and tear brought about by scuff marks.

The 2603 rating identifies powder coatings with a color retention that will not last over a significantly long time.  On the average, the color of the coating would begin to fade after a year of the application.  The gloss retention is insignificant and has a minimum thickness of 0.8mm.  Powder coatings with 2603 rating can withstand at least 1,500 hours of humidity and salt spray abuse before any noticeable damage can be observed.

  • 2604 Specification

Powder coats in this category are considered as intermediary level and are considered best for high traffic area applications because of its durability.  Color retention is quite acceptable with expectations of about 5 years before fading can be exhibited.

There is a projected 30% loss in the gloss of coats in this category after 5 years of application.  The minimum thickness that can be observed is about 1.2mm.  According to the accelerated testing conducted by the AAMA, coats in this category should be able to withstand abuse from salt spray and humidity for at least 3,000 hours before any damage can occur.

  • 2605 Specification

Considered as the highest rating by the AAMA, powder coats falling under this category can be expected to be extremely tough.  The ability of this coat to withstand harsh outdoor conditions for a significantly long time makes it ideal for applications like huge buildings or stadiums.

To fall under this category, the powder coat should have a color retention of at least 10 years with about 50% gloss retention that should be maintained for 10 years at the very least.  The average thickness should be around 1.2mm.  Powder coatings with 2605 rating must be able to stand up to at least 4,000 hours of salt spray and humidity before any substantial damage should happen.

Different Types of Powder Coat for Different Metals

Posted on: November 25th, 2016 by byersbushblog

Did you know that as early as 2010 the demand for powder coating in the global market has reached $5.8 billion?  This market has continuously delivered a rapid growth of about 6% annually, a trend that is projected to continue until 2018 at the very least.

Applied as a free-flowing powder, it does not rely on a solvent to maintain the binder and filler parts in liquid suspension.  This process is used mainly to give metals a strong, high quality coat that can last for decades.  What are the types of powder coat for different metals?

Types of Powder Coat

Typical powder coating techniques rely on two methods, thermoplastic and thermoset.  It is important to understand these methods before we get into the different metals.

  • Thermoplastic – the powder used for this type of coating will melt and flow once subjected to heat. The chemical composition of the powder will not change after it has cooled and solidified.  This is commonly applied to surfaces that have undergone preheating to temperatures that are excessively higher than the powder’s melting point.  The melting of the thermoplastic powder on the hot surface causes it to melt and fusion bond with the surface before it flows out as a strong and continuous film.  After the film cools it creates its own physical properties.  This method works mostly with nylon powder coating.
  • Thermoset –this type of powder melts likewise as it is exposed to heat, the difference is that it chemically crosslinks with itself or possibly with other types of reactive agents. The chemical structure of the cured coating changes from the basic resin used.  This process has coatings that are considered h eat-stable and will never soften even if reheated.

Working with Different Metals

It is important to understand that majority of the technological advancement in powder coating during the past few years have focused on thermosetting powders.  Thermoset materials can deliver a surface layer that is decorative and durable.  The powders have a more brittle resins allowing it to break up into very fine material that can be exceptionally fabricated into very thin and paint-like film that has variable properties to complement metal finishes.

What are the types of resins that allow thermosetting powders to work on different types of metals?  There are 4 generic types that make us this type of powder coating:

  1. Epoxy – hard with an impact resistant exterior, this coating is functional for the delivery of substrate protection. Aside from impact resistance, it is also corrosion resistant and provides essential adhesion.  The main drawback with this resin is its poor performance when exposed to weather.  This is normally used for automotive underbody components, industrial equipment, and, metal appliances and furniture.
  1. Polyester – this powder coat can be used in virtually all types of applications including various chemistries. It creates an extremely durable exterior that is consistent with the 2604 AAMA (American Architectural Manufacturers Association) specification standards.
  1. Acrylic – the automotive industry is the main user of this clear coat material. This resin leaves a smooth and clear coat that is hard and highly resistant to chipping, perhaps why automobile manufacturers prefer to use it.  Addition of this resin improves the flow and leveling including resistance to chemical stains.
  1. Fluoropolymer – this resin is the most ideal to be used on surfaces that are exposed to weather and UV rays. The architectural market is the main beneficiary of this type of powder coating primarily because of its durable finish that is known to last for an extremely long time.  Formulation of this resin can be done in such a way that it complies with the 2605 specifications of AAMA.

There are of course other factors and conditions that can determine how well powder coating methods can perform when subjected to the elements such as continued exposure to heat and humidity.  Equally important is to make sure that the process is carried out by a highly qualified powder coating company like Byers Bush.
