Powder Coating

Laser Precision’s advanced powder coating system utilizes a 7 stage wash with environmentally friendly nanotechnology to provide the finest pretreatment in the industry. The pretreatment system is paired with a dual coat powder system that allows both gel/topcoat application or the new dual coat single cure powder technology. Quick change color modules allow us to rapidly change colors to meet customer requirements. Our paint booths can accommodate pieces as small as a wristwatch or as big as a refrigerator, and our anti-corrosion standards are some of the most rigorous in the industry.

Powder coating is applied as a free-flowing dry powder. It creates a hard finish that is tougher than conventional paint. The coating is applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or a thermoset polymer. Because powder coating does not have a liquid carrier, it can produce thicker coatings than conventional liquid coatings without running or sagging, and powder coating produces minimal appearance differences between horizontally coated surfaces and vertically coated surfaces.

Laser Precision’s powder coating process involves three basic steps:

  1. Pre-treatment – The parts are thoroughly cleaned using an alkaline cleaner to remove all contaminants from the material surfaces. The parts are then progressively rinsed through a series of purified water stages that remove all residue from the cleaning process. In the final stages a conversion coating is applied to the material for corrosion resistance and preparation for powder coating.
  2. Powder application – A variety of powders can be applied to the material after cleaning. Single coat direct to metal, dual coat (gel and topcoat) and dual coat (powder on powder) can all be applied with this system. Surface finishes include matte, textured, semi gloss, and high gloss.
  3. Curing – Curing, or heating the powder to a hardened state to impart an impact resistant finish is the final process in the system. Depending on the selected powder, oven temperatures are selected to bake the finish to the desired finish. In the gel and topcoat process, an independent gel oven is utilized to prepare the primer coat for finish coating. After curing, the resulting finish is impact, abrasion, and corrosion resistant.
