Polyester powder coatings exhibit excellent flexibility and durability with very good outdoor (UV) resistance. They represent approximately 50% of all powders used in North America today. Polyester provides smooth, thin coatings in a full range of glosses, from very high gloss (90%) to very low gloss (5%).

Polyester powder coating is designed to produce thin film coatings in the range of 1 to 4 mils and are applied by the electrostatic cold powder spray method.

Powder Coating Over Chrome

Question: Can you powder coat over chrome. If so, how do you prepare the surface? Answer courtesy of Powder Coating Magazine.

Answer: Yes you can powder coat over chrome plating, but there is no way to prepare the chrome, from a practical perspective, other than degrease and rinse in a high quality water source such as deionized (DI) or reverse osmosis (RO), especially if you are looking for a coating and part that will last.

 

When people ask us how to pretreat stainless steel, we ask why coat it? The same thing holds true for a chrome plated part. Powder coating over a clean and dry surface tend to adhere because have great cohesion and adhesion. Substrates that have been phosphatized, or conversion coated, provide many benefits, including adhesion sites.

Chrome plating is very hard, very thin coating of chrome. Because it’s very smooth, there are no adhesion sites. It will temporarily adhere because of the beauty of powder to encapsulate the part due to its cohesion properties. I’m trying to persuade you not to powder coat over the chrome, unless It’s purely decorative and won’t be exposed to elements like wind and rain.

Powder Coating Over Laser Cut Metal

One of the questions we get asked is “How do you prepare parts after they are laser cut”.  The answer below is courtesy of The Powder Coating Magazine:

 

Question: How do you prepare parts after they are laser cut?

Answer: Laser cut part have a carbon deposit on the edge that must be removed. Iron phosphate and degreaser don’t remove the carbon buildup in most cases. Powder coating over steel with the oxide is similar to trying to powder coat hot rolled steel with scale. It can be done, but the part fails from impact or handling. The best way to treat it is to prevent it by switching to nitrogen and slowing down the feed rate in the laser cutting operation. If you can’t prevent the scale from occurring you must mechanically remove it by sanding, wire brush, or edge blasting of some kind.
