BR 441 Aliphatic urethane acrylate oligomer Bomar Specialties Acrylic Resins >> Polyester Acrylic Acrylic Resins >> Urethane Acrylic Coatings >> UV / Radiation Curing Difunctional polyester urethane acrylates. Rapid cure speed is a standout characteristic of these oligomers. The aliphatic oligomers cure to tough, non-yellowing films with good adhesion to a variety of substrates. The aromatic oligomer provides similar physical properties to that of the aliphatics but it is not recommended for applications where a non-yellowing film is critical. Coatings exhibit excellent oil and chemical resistance. Provides oil and chemical resistance, weatherability, good adhesion and gloss. Difunctional aliphatic polyester urethane acrylate oligomer. Offers rapid cure speed. Produces tough, hard, non-yellowing films. Provides oil and chemical resistance, weatherability, good adhesion to a variety of substrates and gloss.
