Varnishing preparation for composites

Cleaning and scuffing of untreated composites

When manufacturing modern composite materials, all surfaces need to be cleaned to remove mould separating agents and scuffed for downstream coating processes. In this step of the process, standard sanding discs are often used with paper or net backing. However, this application is a tough challenge even for high-performance quality abrasives. We offer a dedicated, unique solution that provides significant cost and time savings for users.
