Purmelt out-performs dispersion adhesives at length, too; and also wins hands down in terms of film elongation and yield strength. For even the toughest tasks, for example when it comes to coated stock with full-surface printing or cross grain binding, Purmelt adhesives constitute a real alternative to conventional edition binding with thread stitching. Purmelt enhances even special binding techniques such as OTA-Bind, opening up opportunities for new varieties such as OTA-PUR. Our Purmelts can look forward to an all-new performance levels thanks to groundbreaking developments in nozzle-application technology. High speeds, coupled with substantial reductions in application quantity – it’s already a reality.
Henkel supplies the Graphic Arts Industry with all adhesive systems necessary for a perfect bond with every conceivable substrate. Made-to-measure solutions are available for the full spectrum of applications and technical configurations.
Dispersion adhesives can be considered the all-rounders of the adhesives world. They excel in virtually every discipline, and are known for their high adhesion performance and good cohesive strength – even if small quantities of adhesives are applied.
Polyurethane hotmelts are the adhesion world champions due to the value it creates in terms of mileage and superior bonding. The outstanding adhesion to the page edges guarantees extremely high binding strength. In the curing process there is a reaction of the polyurethane hotmelt with moisture from the air and paper there by forming an irreversible bond.
