Carboxane 2100 BR is an isocyanate free, ultra-durable, fast-cure corrosion resistant coating that exhibits pronounced growth inhibiting activity against a broad spectrum of bacteria and fungi such as baudoinia (black fungal growth often found in the presence of ethanol and alcohol vapors). This coating provides outstanding color and gloss retention for exterior exposures that exceeds many acrylic aliphatic polyurethanes. It provides good corrosion protection and can be applied direct to metal (DTM) in exposures designated "urban to light industrial" (C1-C4 according to ISO 12944). For improved corrosion protection it can be applied over approved primers. This product meets the most stringent VOC regulations for field applied coatings with less than 100 g/l volatile organic content.
