BR-543TF
BR-543TF: Difunctional Aliphatic Polyether Urethane Acrylate Oligomer
BR-543TF is a difunctional aliphatic polyether urethane acrylate that is tin-free. Films formulated with BR-543TF exhibit superior physical and weathering capabilities. BR-543TF may also be used to improve the flexibility, weathering, and adhesion characteristics of existing film and foil coatings. This product shows a high degree of crystallinity at room temperature.
