B-39

B-39 is a low viscosity monofunctional aliphatic polyurethane acrylate (PUA). It has both a rigid structure of urethane bonds and a flexible carbon chain in the molecule. Compared with ordinary monofunctional acrylate monomers, it has good flexibility and fast curing rate, high double bond conversion rate, low volatility and low irritation and other outstanding features; it can effectively improve the wettability and leveling of the coating and has excellent adhesion to various substrates.
