BRC-441D
BRC-441D: Difunctional Aliphatic Hydrophobic Urethane Acrylate Oligomer
BRC-441D is a difunctional, hydrophobic urethane acrylate 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. It’s ultra-low water absorption makes this an excellent choice for moisture-sensitive or hydrophobic applications.
