UV Cure Acrylate

Acrylate oligomer + reactive thinner + photoinitiator. UV free-radical polymerization films in seconds.

Curing Reaction

PI --(hν, 365nm)--> R·
R· + CH₂=CH-COO- → R-CH₂-ĊH-COO- → Second-level crosslinking

Common photoinitiators 1173, BAPO. Oxygen inhibition causes surface tack; nitrogen protection or amine synergist required.
