Bomar BR-344, a high molecular weight, difunctional, aliphatic polyether urethane acrylate oligomer, is a cost-effective choice for coatings formulations which require weathering durability and non-yellowing characteristics. Formulations with BR-344 result in flexible yet durable, abrasion resistant, non-yellowing systems of moderate- to low-viscosity. It is best suitable for roof coatings and floor coatings.
