1 of 88 products in this brand
Bomar®BR-970H is a low viscosity, difunctional, aliphatic urethane acrylate. BR-970H has 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 application. This oligomer canalsobe used in electronics, and automotive applications
