Additives
There are many additives available that can change the characteristics of the powder coating. These include antimicrobials, metallics and additives to improve outgas resistance.
Powder coatings are now available that contain special silver ion technology. This silver technology provides a safe, natural antimicrobial solution to those cleanliness issues that concern us all. The silver antimicrobial compound, while just one option available today, protects surfaces against the growth of bacteria, fungi, yeast, mold, and mildew.
The market continues to see more and more unique and vibrant finishes using metallics. Metallic or special effect (interference) pigments can be added to powders by dry-blending, bonding, or extruding. Best consistency and reclaimability is achieve through the bonding process, which assures that the effect pigments are physically attached to the base powder coating during the manufacturing process. Aluminum, brass, and copper are encapsulated for better chemical and weathering resistance. The interference pigments refract and reflect incident light to create selected colors. Any change in direction can show off new colors.
Brass and copper pigments oxidize and darken upon prolonged or elevated- temperature exposure. Exterior exposure or high traffic and handling can cause the soft metallic-effect pigments to erode and discolor. A clear topcoat is recommended, especially for oxidizing atmospheres, harsh environments, or high-wear uses.
Outgassing presents many problems for coaters, and is common when coating porous castings. Coatings can be formulated using additives designed to reduce the effect on appearance caused by gases or moisture released from the cast substrate during curing.
