BR-970H
BR-970H is a low viscosity, difunctional, aliphatic urethane acrylate. BR-970H has a high modulus and doesn't necessarily need to be blended with other oligomers to achieve a balance of toughness and flexibility. BR-970H offers rapid cure and non-yellowing properties where premium performance is required. This oligomer is perfect for 2D and 3D inkjet applications as well for use in graphic arts applications.
