BR-572SL: Modified Aliphatic Polyether Urethane Acrylate
BR-572SL is a modified aliphatic polyether urethane acrylate functionalized to promote adhesion. It, like other resins from the BR-500 series, has enhanced toughness and flexibility. Testing has shown BR-572SL has excellent adhesion to glass, metal, and certain flexible films. Because of its strong fatigue properties, BR-572SL may be blended with other flexible resins to produce weatherable, tough, and moisture resistance coatings.
