Pure Polyurethane Ral Color Power Coating

Provides excellent leveling, smoothness and gloss. Superior hardness can be achieved (usually one "pencil" more than TGIC) and is designed for relatively low film build. Certain chemical resistances can be developed to a high level. This product is sensitive to cure parameters; they must be closely followed for optimum results.
