Patent ID: 8366865

Claim:
Adhesive system based on a nonreactive thermoplastic hot melt adhesive, for use in wood processing and furniture processing, including a hot melt adhesive consisting essentially of: (A) a mixture of at least two mutually different metallocene-catalytically manufactured copolymers in each case of ethylene or propylene with at least one linear α-olefin, where the mutually different copolymers of the mixture present different melt-flow indexes (MFIs), where the mixture comprises metallocene-catalytically manufactured copolymers (“copolymers I”) with a melt-flow index MFI≧500 g/10 min, on the one hand, and metallocene-catalytically manufactured copolymers (“copolymers II”) with a melt-flow index MFI≦100 g/10 min, on the other hand, wherein the hot melt adhesive contains mixtures (A) of the different copolymers, with respect to the hot melt adhesive, in quantities of 40-80 wt % and wherein the weight-related copolymers I/copolymers II quantity ratio varies in the range from 6:1 to 5:1; (B) at least one additional polymer, with respect to the hot melt adhesive, in quantities of 0.001-30 wt %; and (C) at least one resin and/or at least one wax, with respect to the hot melt adhesive, in quantities of 0.001-50 wt %; (D) additional ingredients and additives selected from the group of stabilizers, aging protection agents, UV stabilizers, catalysts and solvents.
