Powder Coating Substrates

Posted on: March 21st, 2014 by byersbushblog

Every type of metal has unique characteristics.  Those characteristics will affect how a powder coated finish responds to the surface of the metal.

The properties of the base metal and the surface characteristics of the finished metal will both impact its suitability for powder coating.

The surface characteristics are made up of oxides, hydrates, and salts that together form the metal’s composition.

There are contaminants, as well.  When you are dealing with steel, there may be contaminants such as surface carbons, dirt, bacteria, mildew, fungus, oils, lubricants, metal fines, non-metallic surface inclusions, rolled-in scale, large surface carbides, and corrosion products.

When you are working with zinc, you may encounter contaminants like oils, lubricants, dust, dirt, soil, corrosion products, and metal fines. Aluminum brings many of the same contaminants as zinc, with the addition of aluminum oxide.

Because there are so many different possible contaminants and many different types of metals, there is no single method of part preparation for powder coating that is suitable for every situation.

The method used for preparing a part for powder coating will vary based on the type of metal and the contaminants present.

Types of Steel

Steel is an alloy of carbon and iron. There are additional small amounts of other elements in steel, as well.  There are many different gauges of steel, each of which has different properties.

Hot & Cold Rolled Steel

Hot rolling is used to produce heavy gauges of steel.  Hot rolling is the first step in creating a steel slab.  The resulting surface has a layer of mill scale.  This scale often loosens during the manufacturing process.

For this reason, hot rolled steel that has not had the mill scale removed is not a good candidate for powder coating.  The coating does not adhere well.

The mill scale must be removed prior to coating using acid pickling or mechanical cleaning.  Welded areas on hot rolled steel must be removed through mechanical cleaning using a wire brush or sandblasting prior to coating.

Cold rolling steel produces thinner gauges of steel.  Cold rolled steel does not have mill scale and carbon dust on its surface like hot rolled steel, but it does have some oil that serves as a rust inhibitor.  It can be chemically cleaned to prepare it for powder coating.

High Strength Low Alloy Steels

High strength low alloy (HSLA) steels are an alloy blend that are used to obtain a better ratio of strength to weight.  They can usually be prepared using the same methods as carbon steels.

Surface oxidation can be removed by grit blasting.  When HSLA steel is blasted to white metal, some shadowing may occur.

This shadowing is not a problem, and powder coating can still be applied and achieve good adhesion.  However, some types of HSLA steel contain silicone.  The silicone can interfere with cleaning and coating.

Stainless Steel

Stainless steel does not contain many of the common surface contaminants as carbon steel.  Prior to coating, stainless steel should be cleaned to remove any dirt or surface oils it may have picked up while being handled.

Since stainless steel doesn’t react to environmental triggers like other metals, it usually does not have a protective coating.

It has a passive oxide layer that means that the chemicals that are used to clean carbon steel will not affect stainless steel.  Mechanical abrasion can be used to remove the oxide layer and create a rough surface that will adhere to powder coating.

Powder Coating for Auto Rims

Posted on: March 20th, 2014 by byersbushblog

Are you thinking about powder coating the rims on your sweet ride?

Before you get started, read up on what powder coating entails and how it should be done properly.

Clean Thoroughly

The first and most important step in powder coating rims is cleaning them thoroughly.  It doesn’t matter what size, shape, design, or style the rims are – they must be perfectly clean and free of grease or oil before they can be powder coated.

Any type of contaminant, even dirt, will prevent the powder coating from adhering to the metal properly.  Professional powder coating companies typically use sandblasting or grit blasting methods to clean rims before powder coating them.

Sandblasting will remove any dirt, grease, or old paint from the rims so that they are clean, smooth, and ready for powder coating.

Professional Powder Coating Service Provider

It is best to take your rims to a professional powder coating company to be powder coated rather than trying to do the job yourself.

A professional company has all of the necessary tools for the job, and they also have the experience to achieve a perfect finish.

A professional can powder coat your rims much more efficiently; you might have to make several practice attempts and waste a lot of powder coating before you are able to coat the rims.

When you take the rims to the powder coating company, make sure that they have experience in working with rims and have all the tools and supplies that are necessary for working with such a product.

The powder coating is available in a wide variety of colors, textures, and finishes that you can choose from.

Prevent Unwanted Parts to Be Coated

Before the powder coating can be applied, any areas that should not be coated must be removed or taped off.  Taping those areas will prevent them from being coated.

After the powder coating is applied to the rims, they must be cured in an oven.  The powder coating is sprayed on to the rims, and then placed in a 400° oven.

In the oven, the rims are baked, and the powder coating essentially melts on.  Since the coating melts, it can run a bit.  If it runs into the lug holes, the holes can become narrowed.

If the holes become too narrow, they can be reamed out a bit so that the lug nuts fit properly.

Choose Your Color

It is important that you are sure in your choice of color and finish before the powder coating process begins.  There are many colors and finishes to choose from, including metallic and textures.

Most companies have sample cards, just like paint chips, that you can look through to help you decide.  Once the powder coating has been applied and cured, it’s too late to change your mind.

If you don’t like the color or finish, you will have to start the whole process over again, which could get expensive.

Powder coating your rims is a great way to protect them and keep your car looking brand new.

How to Estimate Pricing for a Powder Coating Finish

Posted on: March 19th, 2014 by byersbushblog

Are you considering powder coating service? If so, one of your first questions will probably be, “what will it cost?” There are a variety of factors that affect what it will cost to have an item powder coated.

Use these guidelines to help you get an idea of what to expect.

1st Factor – Is the item new or used? 

If the item is new, it probably will not need to be cleaned prior to being powder coated.  However, if the item is used, it may have a buildup of grease or dust.

If so, it will need to be thoroughly cleaned using solvent to prepare it for powder coating.  In order for the powder coating to adhere to the item’s surface, the surface must be completely clean.

When the item requires cleaning prior to powder coating, there is typically an additional charge.

2nd Factor – Is the item taken apart and ready to be powder coated? 

In order to properly prepare the surfaces, all items must be disassembled before they can be powder coated.  Disassembling the item also protects it.

The oven that is used to cure the powder coated item reaches 400° F. Any components that cannot tolerate extreme heat must be removed to keep them from being damaged.

If there is any portion of the item that you do not want to be powder coated, that portion must be removed or taped off.

There is an additional charge for disassembling your item prior to powder coating.

3rd Factor – Does the item need to be sandblasted prior to powder coating? 

Powder coating must be applied to a clean, smooth surface in order for the coating to adhere properly.

Items that have a textured finish or have been exposed to weather or rust will need a sandblasting service to achieve the necessary smooth finish.  New items sometimes need to be sandblasted to remove welding slag or smooth a rough finish.

If your item needs to be sandblasted to prepare the surface for powder coating, there will be an additional charge.

4th Factor – What kind of powder coating do you want? 

Powder coating is available in lots of different textures and colors.  Not every option is the same price.  Our stock powder coating prices are a standard price.

If you want a specialty color or a metallic or texturized finish, there will be an additional charge.

5th Factor – Do you need a clear coat? 

Typically, just one coat of powder coating is applied, and that achieves a beautiful, durable finish. The cost for a clear coat is based on the surface area to be covered as well as the difficulty in handling the product.

If you want a specialty powder coat, though, like a candy finish or metallic, you may need an additional clear coat.  In cases like these, the clear coat adds depth to the finish and gives it an additional layer of protection.

6th Factor – How big is the item that will be powder coated? 

The cost for powder coating an item depends on the surface area of the item to be coated as well as the level of difficulty in handling the item.

Therefore, the size of the item and the amount of detail involved in powder coating it will affect your cost.

These are six factors that will affect your total cost for powder coating.

The Benefits and Myths of Powder Coating

Posted on: March 18th, 2014 by byersbushblog

You may have heard of powder coating as an alternative to painting.  But do you know what the powder coating process really is?

How Does Powder Coating Work?

Powder coating is the process of applying a finish to a metal product.  It is similar to painting, but the medium is a fine powder that is sprayed on to the product.

Powder coating is a dry process; it uses a dry powder instead of wet paint.  The powder itself is made up of finely ground particles of pigment and resin that are electrostatically charged.  The powder is sprayed onto the product to be coated using a spray gun.

The product being coated is electrostatically grounded, and the powder is electrostatically charged, which makes it stick to the product.  Any excess powder that is over sprayed can be collected and reused.

After the powder has been sprayed on the product, it is baked in a very hot oven (around 400°) to cure it.  The curing process basically melts the powder, and then it hardens to a uniform and consistent finish.  The resulting product is high-quality and has an attractive and durable finish.

Benefits of Powder Coating Instead of Painting

Powder coating is preferable to painting because it is much more environmentally friendly.  Liquid paint contains volatile organic compounds, or VOCs.

These compounds are dangerous to the environment and our health.  The powder used in powder coating is extremely low in VOCs, so it is much safer to use.  No solvents are necessary, and it is safe to handle and can be disposed of easily.

Since excess powder can be gathered up and used again, it reduces waste.  Powder coating is so safe that there is no need for pollution control equipment.

Another benefit of powder coating is that it provides an extremely durable finish.  It is one of the most long-lasting and economical finishing choices available.

When a surface has been powder coated, it is resistant to chipping, scratching, and fading.  There are tons of color choices to choose from, as well as high and low gloss finishes, metallics, and clear coats.

Powder coated finishes retain their bright, vibrant color for longer than paint.  There are many texture choices available, as well; you can get a smooth, wrinkled, rough, or matte finish.

Myths about Powder Coating

  1. Powder coating will never chip.  This is not true.  Powder coating is resistant to chipping and is much less likely to chip than liquid coatings, but we cannot guarantee that it will never chip.  If the impact is hard enough, it may chip.
  2. Exposure to weather will make powder coating fade.  This is not true.  There are certain types of powder coating that are intended for extended outdoor use.  They are used in architectural applications, and can retain their color for more than 15 years.  If your item will be used outdoors for an extended period of time, talk with the professionals at the powder coating company about what type of powder coating is best for your application.
  3. UV exposure will make powder coating lose its gloss.  This is not true.  Powder coating offers excellent UV resistance.

Environmental Benefits of Powder Coating

Posted on: March 18th, 2014 by byersbushblog

Do you have an item that you are considering painting or powder coating?  Are you unsure of which type of coating you prefer?

Powder coating is a great option.  It seals and protects the item and prevents damage from moisture or corrosion.  Powder coating is available in many different colors, textures, and finishes, just like paint.

But what about the environmental impact?  Take this into consideration:  powder coating provides a much more environmentally friendly alternative to painting.

Let’s take a look at these 5 ways in which powder coating is environmentally friendly.

The Powder Used in Powder Coating Is Reusable. 

Powder coating is applied by spraying it on, which means that some of the powder misses the item being coated and falls on the floor.

It doesn’t all stick to the part.  Does that sound wasteful? It’s not, because the unused powder can be collected and reused on another item.

Powder coating facilities always have a reclaim system in place that allows them to gather up the overspray and reuse it.  This keeps costs down while also reducing waste.

Powder Coating Reduces Hazardous Waste. 

When you compare powder coating to conventional liquid coating, you will see that powder coating creates significantly less hazardous waste than conventional liquid coating.

Think about what a hassle it is to dispose of leftover paint; your garbage man won’t even pick it up.  Powder coating is completely safe to handle and discard.  You can just pick up the overspray.

If there are any mistakes in the coating, you don’t need to use paint thinner to remove them.  Before the item is cured, you can just blow off the powder coating and spray again.

Powder Coating Is Considered To Be Non-Toxic. 

Paint is full of volatile organic compounds (VOCs).  VOCs have played a big role in damaging the ozone.  Powder coating has almost no VOCs, so it is much safer for the environment than paint.

Powder Coating Doesn’t Create Dangerous Fumes. 

Think about the chemical smell that is created when you paint a room; you have to open all the windows to let the fumes out.  Powder coating is non-toxic and does not fill the space with dangerous fumes.

You don’t even need to vent the exhaust to the outdoors when working with powder coating, because the air is clean and safe to breathe.  When the powder is airborne, it is nothing more than a nuisance dust.  It does not pose any serious risks.

Powder Coating Meets Environmental Regulations.  

There are many regulations in place that serve to ensure that chemicals and other materials do not damage the environment.  Powder coating processes comply with those environmental regulations.

The products are much easier and safer to work with than wet paint.  Finishing a product with powder coating instead of paint is a safer, more environmentally alternative option.
