Title (EN) HOT-MELT,PRESSURE SENSITIVE ADHESIVES
(FR) ADHESIFS, FONDUS A CHAUD, SENSIBLES A LA PRESSION
Abstract: front page image
(EN)Blends of plasticizing oils and compatible tackifying resins with substantially amorphous or semicrystalline olefin copolymers containing a C3 to C5 linear (Alpha) -olefin and 15 to 60 mole percent of a C6 to C 10 linear (Alpha) -olefin which are useful as hot-melt, pressure-sensitive adhesives. The unmodified copolymer base resins have melt viscosities in the range of 5,000 cp up to 1,000,000 cp at 190 C. The addition of the plasticizing oils and compatible tackifying resins to the copolymer base resin causes an unexpected increase in the shear adhesion failure time in addition to improved coatability as well as substantial increases in probe tack and peel adhesion values of the copolymers.
(FR)Les adhesifs sont constitues de melanges d"huiles plastifiantes et de resines adhesives appropriees avec des copolymeres d"olefines amorphes ou semi-cristallines contenant une olefine lineaire C3 a C5 et 15 a 60% en moles d"une olefine C6 a C10. Les resines copolymeres de base non modifiees ont des viscosites a l"etat fondu de l"ordre de 5,000 cp a 1,000, 000 cp a 190 C. L"addition d"huiles plastifiantes et de resines adhesives appropriees a la resine copolymere de base a pour resultat inattendu d"augmenter le temps de rupture d"adhesion en plus d"une amelioration dans le revetement ainsi que dans l"adhesion et le pelage.
