Protecting Your Valuable Bicycle with Powder Coating

Posted on: November 29th, 2016 by byersbushblog

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.

Knowing AAMA Rating in Powder Coating Application

Posted on: November 27th, 2016 by byersbushblog

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.

Various Kind of Materials That You Can Powder Coat

Posted on: November 23rd, 2016 by byersbushblog

First introduced in North America more than 40 years ago, powder coating is a type of dry finishing process that represents over 15% of the industrial finishing market.  Powder coating can be used on a wide range of products and materials.  It is important to understand that the materials that can be subjected to powder coating should be able to withstand temperatures reaching 400 degrees for an extended time.  So what are the materials that you can powder coat?

Metals

Definitely, the most common material used with powder coating is metal.  When used with metal, the powder undergoes a process where it is electro-statically attracted to the material while it is grounded.  The material will then be cured under heat to allow the formation of the coating similar to a skin.

To create a hard finish that is comparatively tougher than conventional paint, thermoset polymer or thermoplastic powder is used.  The most common types of metals that undergo powder coating are drum hardware, household appliances, aluminum extrusions, bicycle and automobile parts.

The thermoset powder will begin to melt flow out when it is exposed to extremely high temperatures.  It will then chemically react to create a polymer with a higher molecular weight though a crosslinking curing process.  Once the material reaches full cure, the full film properties of the material will begin to develop.

Non-Electrically Conductive

When we speak of non-electrically conductive materials, this pertains to wood, plastic, or glass.  These materials cannot be sprayed with powder because the material will simply fall off and will not stick as intended.  To compensate for this, pre-heating is done.  It is important that not all kinds of plastic materials can withstand the pre-heating process so you have to choose wisely.

Heating non-electrically conductive materials is normally done using an oven.  The object is removed while it is hot and powder coated before it cools off.  Once the powder hits the heated portion of the material, it slightly melts on contact allowing it to stick.  Once the area has been coated, the material is placed back in the over so that it can be cured.

For these types of materials, there will be a tendency to apply an extremely thick coating, especially if you are doing it for the first time.  This is primarily because the powder melts immediately once it hits the pre-heated material making it difficult to assess whether enough coating has been produced.  What is the problem with too much coating?  Just like paint, there will be the possibility of running, formation of craters, and eventually chipping.

Glass Container

The chosen glass container must be certified safe for baking at roughly 450 degrees.  All the gluey parts like the stickers, lids, or rubbery gaskets should be removed before the glass container is placed in the oven.  It should then be cleaned off with soapy water and thoroughly dried.

If it is your first time to try this, make sure that you have enough pieces to work with.  Separate them into batches so you can make the necessary adjustments.  If you plan to paint the coated pieces after, you need additional test strips.  Any type of glass can do, not just jars, provided that it will attract the powder and allow the powder coating process to happen.  Keep on adjusting the process until you are satisfied with the way the powder sticks to the glass or achieve the look you are going for.

Not many people know that powder coating can be done on a variety of materials.  More importantly, the same quality and beautiful finishes that can be done with metal can be duplicated with other types of materials as well.  Now, all you have to do is to let out that creative spirit and you can do wonders with the materials that you can powder coat.

Using Powder Coating to Restore Old Car

Posted on: November 21st, 2016 by byersbushblog

Do you have an old car that you want to restore?  Is there a specific finish that you have in mind?  It does not matter if you want to restore a classic muscle car or a relatively newer one, the focus of restoration is normally on matching the finishes of the original vehicle.  So what are the options that you have when restoring an older car and its smaller parts?

Spray Painting

This is one of the cheapest and easiest solutions in car restoration.  However, this also translates to a cheap look to your restoration and does not have the desired durability, which means having to restore it again after a short while.  You also have to worry about chipping and scratches because the paint can be easily damaged.  This also means that rust can be a very valid concern.

Automotive Paint

How about 2 part automotive paint, it is made for automobiles after all, right?  There is no question that you can achieve a great look and it is durable as well.  This type of coating will also withstand rust for quite a number of years.  Unfortunately, this is quite a costly solution and if you want to use different colors for your car and the spare parts, you would have to shell out around $30 a pint.

You also have an added cost of about $30 for the hardener.  Every coat needs its own hardener, which means that you will be spending over $100 for every color or gloss-level you want to use.  You also need to use several layers of primer, paint, and clean the paint gun before another application.  This means spending a lot of time and money in the restoration process.

Plating

The choices are zinc, chrome, cadmium, and nickel among others.  Chrome is by far the most popular, but also very expensive.  Using other plating methods will require a minimum order to get a good price, for example a plated bracket can be priced the same as 100 brackets.  You also have to take a look at the pros and cons of each plating method.

Powder Coating

This is not a magical solution, but it is one of the best options in restoring old cars.  Not only will the vehicle look great, it will also have a durable protection, and can be rust-free for a substantial period.  It is also a very cost-effective solution especially if you want to use different colors.  Half a pound of powder will only cost you around $7 with another $7 for the clear.

This means restoring an old car with powder coating can be as cheap as $14 for the parts.  Media blasting will be required or at the very least getting to the clean bare metal.  This will allow the powder coat to stick properly.  Subjecting it in the oven for 20 minutes at the proper temperature and allowing it to cool will give you the desired result.  Considering that you can get a beautiful finish that can last for well over 20 years for $14 in less than an hour is a pretty good deal.

 

Contrary to common belief, powder coating is not limited to valve covers and car wheels.  This means that you can use it to treat all the small car parts involved in the restoration process.  Compared to the time and money you have to spend with spray painting and plating, powder coating seems to be the best option for you.  The best part is that you get the same quality finish at a fraction of the cost.

 

The key to ensuring that you get the best result with powder coating is to get a company that offers quality sandblasting and powder coating services combined with excellent turnaround time.
