Unlike liquid paints, powder coating does not use any solvents...eliminating V.O.C.'s (Volatile Organic Compounds).
AAMA 2603 powders come with a 10-year factory warranty.
The mechanical durability of powder greatly exceeds wet paint.
Requires less energy to produce (Can be up to 30% less than liquid).
Excess powder in the application process can be reclaimed...eliminating waste.
Powder can be applied at higher film builds than liquid.
Disadvantages
Difficult to touch-up in the field with a good color match.
Applicators cannot perform in-house blending and color matching.
Powder coating requires a greater film thickness and is difficult to achieve lighter film thickness without creating an orange peel effect.
Some powder paints are not as economical as their equivalent in wet paints.
Powder coat paints cannot provide the brillance of a metallic look as with liquid paints, due to powders inability to hold the same metallic flake content.
Single coat powder paints on aluminum are susceptible to filiform corrosion.
Types of Powder Paints...
There are (2) basic types of powder paints:Thermoplastic -Powders that will remelt when heated & Thermosetting - Powdersthat will not remelt upon reheating (Keymarksprays only Thermosetting powder paints).

The Powder Coating Process...
Extrusions are loaded on racks and are submerged in a pretreatment tank (40 feet in length) containing chrome phosphate. Chrome Phosphate has proven to be the premier pretreatment for powder paints to ensure the highest level of performance and adhesion. This is also the most important part of the entire painting process.
Parts are dried in an infrared oven before the application process.
In the application process, the extrusions travel into the powder booth where powdered resins along with colored pigments are applied to the extrusions through the useof automatic spray guns andan electro-static charge.
The extrusions then enter a separate high temperature bake oven (350-425 degrees) for approximately 20 minutes and thiscauses the powder to melt, flow, and then cure, forming a molecular fusion bond.
The end result is hard surface to coating bonding unlike any other
Most jobs are done within a few days, depending on your needs.
Huge selection of colors in stock - and custom colors to fit your any need.
Durable surface offers protection from the elements 3-5 times longer than paint!
Uniform coverage - minimal color fading - with a variety of textures and styles.
Our sandblasting service removes old paint, rust, grease ensuring a clean surface.
Powder coating is extremely resistant to chipping, flaking, solvents, corrosives, and general wear and tear. This durability makes powder coating a superior protective coating for all metal products.
Each piece brought to us is prepared through chemical stripping, degreasing, or sandblasting to ensure an absolutely clean surface ready for coating. The coating is evenly applied in a powder form and then baked. Resulting in a hard, smooth, paint-like finish that will bend with the metal if dented or struck. The versatile properties of powder coating make it ideal for a variety of needs, both decorative & practical.
