Binding - COLD GLUES & HOTMELTS - PURMELT
This new generation of adhesives is distinguished by the exceptional adhesion to a wide variety of papers and other materials. With a layer thickness of only 0.3 to 0.6 mm, they differ significantly from conventional adhesive systems. Depending on the humidity and the moisture of the paper is 50 to 80% of the adhesion strength is already reached after 6 hours. The final curing is achieved after 24 hours.
After reaction, the Purmelt film demonstrates a high flexibility at high and low temperatures. Brochures glued with Purmelt retain their quality up to 120░ C and remain elastic rather than to become brittle, and this to a temperature of -40░ C.
