Bomar® BR-643

Bomar® BR-643 by Bomar is a radiation curable, difunctional aliphatic polybutadiene urethane acrylate. It exhibits acid/base resistance, hydrophobicity, hydrolytic stability, low water absorption and excellent dielectric properties. Offers improved adhesion, low temperature flexibility and glossy finish. It is recommended for rigorous electronic coatings. In applications requiring thermal cycling resistance, Bomar® BR-643 withstands the extremes of temperature typical of such tests, without undue degradation of properties.
