- Urethane Acrylate/Isocyanate
BR-371MS, a low molecular weight, difunctional, aliphatic polyether urethane methacrylate oligomer, is a great fit for coatings that require high tensile strength, extremely low color, superior hardness, scratch resistance, and weathering resistance. BR-371MS provdes very low color and a high viscosity, ideal for hard gel nail coatings, and offers reduced heat generation vs other high tensile strength materials.
