Hot-melt adhesive systems with rapid bond strength
Hot-melt adhesives (non-reactive or reactive) are solid at room temperature and liquefy when heated. They are applied at high temperatures and during the cooling process they solidify and crystallize to produce an adhesive bond which rapidly develops a considerable bond strength. In the case of reactive polyurethane hot-melt adhesives, chemical bonds are additionally formed.
Common raw materials for reactive polyurethane hot melts are Desmodur® monomer MDI grades, Baycoll® polyesters, Desmophen® polyesters and Desmophen® polyethers.
Typical applications include adhesives for wood and furniture, automotive and transportation solutions, bookbinding, textiles, footwear and electronics.
