BR-144B: Trifunctional Aliphatic Polyether Urethane Acrylate Oligomer

BR-144B, a medium molecular weight, trifunctional, aliphatic polyether urethane acrylate oligomer, offers the formulator a cost effective means of obtaining high abrasion resistance and solvent resistance in a durable, high-gloss coating. While not limited to these fields, BR-144B is an effective choice in wood and furniture applications, along with abrasionresistant overprint varnishes. This material has low skin sensitivity for dental and cosmetic applications.
