More Information
Summary:The invention relates to a storage-stable hot-melt adhesive containing 15 to 70 wt% of a mixture of at least one copolymer based on ethylene and/or propylene and at least one C4 to C20 alpha-olefin, which can be obtained as a block copolymer by metallocene-catalyzed polymerization, and at least one styrene block copolymer, 10 to 70 wt% of at least one tackifying resin, and 0 to 40 wt% of additional additives, wherein the sum of the % shares should equal 100% and the tackifying resin is completely or partially a soft resin.
