Crestapol® 1240

Crestapol® 1240 is a urethane acrylate-based over-laminating resin designed for re-laminating polyester composite panels, including those produced by infusion. It eliminates the need for surface preparation, such as sanding or priming, reducing time and cost. With excellent adhesion performance, it supports various assembly configurations without requiring a primer, making it suitable for efficient composite manufacturing and repair applications.
