Description and Uses

A positive patch test was observed in a male process worker in a paint factory, sensitized to an epoxy diacrylate (1,4-butanediol diacrylate) contained in raw materials of UV -light-curable paint. The positive reaction was probably due to a cross reactivity.

1,4-Butanediol diacrylate may be used as a multifunctional crosslinker.
