L216 Curing Accelerator for Powder Coating

Product Detail

L216 Curing Accelerator
L216 is a generic accelerator, not only accelerate the curing for epoxy/polyester hybrid powder, but also accelerate the curing for pure polyester system. The effects of improving curing, anti-yellowing are very obviously.
