BR-543
BR-543: Difunctional Aliphatic Polyether Urethane Acrylate Oligomer
BR-543 is a difunctional, aliphatic, polyether urethane acrylate. Films formulated with BR-543 exhibit superior physical and weathering capabilities. BR-543 may also be used to improve the flexibility, weathering, and adhesion characteristics of existing film and foil coatings.
