The active hydroxy group can be reacted with suitable functionalized unsaturated resins.
It provides surface, through and LED cure.
It is designed for white, clear and pigmented systems.
It is used in UV curable formulations on substrates like wood, metal, plastic and paper.
It demonstrates low volatility and low odor as a pure substance as well as in cured films.
