UV/EB Oligomer
BR-7432GI30
BR-7432GI30: Difunctional Aliphatic Polyester Urethane Methacrylate Oligomer
BR-7432GI30, an aliphatic polyester urethane diacrylate, formulates into applications requiring adhesion to various substrates and applications where excellent toughness and
flexibility are required. The BR-7432GI30 backbone performs very well in extended weatherability studies. It is an excellent choice for impact and bend resistant coatings, and can act
as an impact modifier for composite applications.
