Q. I need to powder coat plastic materials, specifically white polycarbonate resin. It’s a general-purpose, medium-viscosity RTI 125C. Do you know if there is some metallic coat or adhesive bonding (conductive surface) available that will allow the powder coating application? B.G.
A. The material you seek is called “Rans-Prep.” It is a conductive liquid primer that can be applied over most any substrate to make that surface conductive for electrostatic application of liquid or powder coatings.
Infrared cure is gaining increased attention from coaters as a result of shorter cure cycles and the possibility of smaller floor space requirements when compared to convection oven curing.
How can you calculate the cost of powder coating a component if you only know its surface area? Powder coating expert Rodger Talbert has the answer.
Powder coating is one of the most durable finishes that can be applied to industrial manufactured products, and offers excellent corrosion protection and is very safe because of its lack of volatile organic compounds.
