BRC-843SL
BRC-843SL: Modified Aliphatic Urethane Acrylate
BRC-843SL is a modified aliphatic urethane acrylate functionalized to promote adhesion. It has a strong hydrophobic character and may be used by itself as a co-resin. The resulting film makes a tough, non-yellowing protective coating that will extend the life of any substrate. Low water absorption and enhanced thermal properties make BRC-843SL ideal for finishing in numerous industries including aerospace, cosmetics, automotive, electronics, and on medical devices. BRC-843SL is moisture sensitive and shows excellent adhesion to multiple types of non-porous/plastic substrates including PET.
