摘要

PROBLEM TO BE SOLVED: To provide an excellent hot-melt adhesive for interior automotive trim, capable of being used in coating the trim by using a spiral spray or a roll coater, preventing a fogging phenomenon, and having a high deodorizing effect on odors in a cabin.;SOLUTION: This hot-melt adhesive for the interior automotive trim is obtained by mixing (B) a tackifier resin in an amount of 50-800 pts.wt. and (C) a liquid hydrocarbon having a melt viscosity of of ≤55,000 mPa.s at 100°C in an amount of 50-300 pts.wt. into (A) a styrene-isoprene-styrene block copolymer, a styrene-butadiene-styrene block copolymer, a hydrogenated product of the styrene-isoprene-styrene block copolymer, and/or a hydrogenated product of the styrene-butadiene-styrene block copolymer in an amount of 100 pts.wt., wherein components having a molecular weight of ≤400 are contained in the hot-melt adhesive in an amount of 7 wt.% based on the total amount of the mixed materials (A), (B), and (C).;COPYRIGHT: (C)2004,JPO
