BR-400 Series Oligomers	Difunctional and trifunctional polyester urethane acrylates. The aliphatic oligomers cure rapidly to tough, non-yellowing films with good adhesion to a variety of substrates. The aromatic oligomers provide similar physical properties to that of the aliphatics, but are not recommended for applications where a non-yellowing film is critical. Coatings exhibit excellent oil and chemical resistance.
