B-39 Aliphatic polyurethane acrylate

B-39 is a new type of low viscosity monofunctional 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.
