Manufacturers use polyurethane porcelain enamel coatings in a wide array of environments, often as a protective final coat over other custom formulated industrial primers. Polyurethanes resist abrasion, and can enhance durability to withstand wear and tear and abuse.
These porcelain enamel coatings maintain color and can have an attractive, high-gloss finish, if desired. Aliphatic polyurethane porcelain enamel coatings have good UV and environmental durability. Such porcelain enamel coatings are a good choice for outdoor applications.
Aromatic polyurethane products resist degradation in wet conditions or underwater, but they tend toward fading when exposed to UV light. These porcelain enamel coatings can work well in interior environments.
Two component polyurethanes do require protection for workers when applied, as with many other types of chemical processes. They are available in low VOC formulations.
