Bomar Oligomers® BRC-842MB

BRC-842MB is a difunctional, hydrophobic urethane methacrylate that can be formulated into chemical and temperature resistant coatings and resins. The material has low color and excellent adhesion to a wide variety of plastics. The material can be formulated into tough, impact resistant 3D printing resins with excellent flexibility. Its ultra-low water absorption makes this an excellent choice for moisture sensitive or hydrophobic applications.
