Bomar Oligomers® BR-542MB

BR-542MB is a difunctional, aliphatic polyether urethane methacrylate. BR-542MB is used for its desirable balance of toughness and flexibility and its ability to adhere to a variety of substrates. As a primary oligomer, BR-542MB offers excellent properties of adhesion and optical clarity. As a co-oligomer, BR-542MB can be used to improve an existing formulation's glass adhesion.
