Dynacoll 7320 Saturated polyester Degussa Polyester >> Saturated SEALANT ADHESIVE >> Hot-melt ADHESIVE >> Reactive system DYNACOLL 7300 series, Saturated polyesters partially cristalline effects on reactive hot melt: shortens open time (depending on crystallinity) increases initial strength lowers melt viscosity Building block system for the production of moisture-curing hot melt adhesives (reactive hot melts = RHM) for: Automotive sector, wood-processing industry, bookbinding, packaging industry, textile industry, production of sancwich structures Partially cristalline saturated polyester. Shortens open time. Increases initial strength. Lowers melt viscosity. Used in hot melt adhesives for automotive sector, wood-processing industry, bookbinding, packaging industry, textile industry, production of sandwich structures. Open time: >500 seconds
