Bomar Oligomers® BR-146

BR-146, a high molecular weight, trifunctional, aliphatic polyether urethane methacrylate, provides low formulation viscosity and moderate elongation with nonyellowing properties appropriate to soft touch glass coatings and impact resistant coatings. BR-146 shows adhesion to a variety of substrates, making it a candidate for consideration in mixed surface adhesion applications.
