Abstract:
The present invention pertains to a stabilized hot melt adhesive containing a) one or more hot melt adhesive materials and b) a stabilizer composition. The one or more hot melt adhesive materials a) include a polyolefin, a styrene-isoprene-styrene block co-polymer, a styrene-butadiene-styrene block co-polymer, a polyacrylate, an acryl-copolymer, an ethylene vinyl acetate, a polyamide, a polyester, a polyurethane, a polyimide, a silane terminated polyolefin, a silane terminated poly-ether, and a silane terminated polyurethane. The stabilizer composition includes two or three of a component (A) which is a specific sterically hindered amine, a component (B) which is a polymeric sterically hindered amine, and a component (C) which is a specific sterically hindered phenol.
