Carboxane 2100 FC is a premium, ultra-durable, fast-cure coating that provides outstanding gloss and color retention for exterior exposures. It combines the chemical resistant properties of epoxies with the weathering characteristics of acrylic-polyurethanes. This tightly cross-linked film results in a finish with outstanding barrier properties and weathering performance that far exceeds polyurethanes. This product meets the most stringent VOC regulations for field applied coatings of less than 100 g/l volatile organic content. It is most often used as the finish coat of a two-coat system utilizing a zinc-rich primer for maximum corrosion resistance and longevity. It can be used as a direct-to-metal (DTM), self-priming coating in exposures designated "urban to light industrial" (C1-C3 according to ISO 12944).
