DESCRIPTION

One of the highest quality powder coating technologies is based on acrylic resins. Some of the very first thermosetting powders were based on acrylics, with powder technology based on acrylic resins having been around since the 1970s. Acrylic clear powder coating provides an array of performance that is truly a cut above the rest, and can offer excellent chemical resistance, superior exterior durability, exceptional chemical resistance and outstanding smoothness. The following is a summary of some acrylic chemistry available in powder coatings and their general performance levels.

 

Acrylic clear powder coating provides excellent smoothness for vehicle application. Acrylic clear powder coating is a GMA acrylic powder that is excellent for high performance of exterior weather-ability, durability and abrasion resistance. All GMA acrylics are well known for their excellent weathering resistance which can provide coatings resistant to over 10 years of exposure. These types of powder acrylic resin solutions have been used since 1998 as a clear topcoat for BMW automobiles. As you can surmise, not only does this technology possess excellent UV durability, but also remarkable resistance to various environmental conditions, cleaning agents, and even gasoline spills.

There are two issues of note with acrylic powder technology. The cost is much higher than other choices for vehicle application, and there can be compatibility issues with other powder coatings as well. Both of these issues can cause manufacturers to reconsider using acrylic powders, in spite of their far superior durability and overall performance. Compatibility issues in most acrylic formulas will cause crater defects in a polyester powder coating due to the significant difference in surface tension between acrylic polymers and polyester resins. Because of this, you must keep acrylic based powders away from contact with other non-acrylic varieties. This can easily be accomplished by being very thorough with cleaning up when switching from an acrylic to other powders, and by having a dedicated application system.
