HENKEL: Hot-Melt Adhesive

July 27, 2010

To reduce the distortion of fiberglass-reinforced panels (FRPs) exposed to direct sunlight, this company has introduced a new urethane hot-melt adhesive formulated to withstand temperatures above 200°F. Purmelt® R-200F+ improves distortion resistance up to five times longer than traditional polyurethane adhesives, and it allows manufacturers to use dark graphics and full-body paint on sidewall designs.

Suitable for roll coating processes, the patent-pending adhesive was developed to allow RV manufacturers to create aesthetically pleasing graphics and paint schemes without straining the fiberglass-reinforced plastic substrates on exposure to sunlight. Results from long-term durability testing show no distortion on panels made with the adhesive after 40 hours of exposure at 200°F.
