HOT MELT ADHESIVE COMPOSITION HAVING IMPROVED WET BONDING STRENGTH

摘要

The invention relates to a hot melt adhesive composition comprising a polymer component, the polymer component comprising at least one styrene-butadiene-styrene block copolymer P having a styrene content from 35 to 50 % by weight; a styrene-butadiene diblock content from 50 to 80 % by weight; and a viscosity of a 15 % by weight toluene solution at 25°C of 20 to 40 mPa.s, and at least one styrene block copolymer other than a styrene-butadiene-styrene block copolymer, wherein said styrene-butadiene-styrene block copolymer P is at a content from 10 to 40 % by weight relative to the total weight of the polymer component.The invention also relates to the use of said composition as an adhesive for bonding two substrates, and to articles comprising at least one interior or exterior surface coated with said composition.
