- Chemical Family
- Urethane Acrylate/Isocyanate
BR-771F is a low molecular weight oligomer with a good balance of high tensile strength and moderate elongation with an excellent cure speed. BR-771F exhibits excellent adhesion to plastic substrates, particularly polycarbonate. Formulations made with BR-771F can exhibit superior toughness properties with a high Tg. Its inherently low color and aliphatic backbone make BR-771F an excellent candidate for polycarbonate coatings and adhesives
