Title (EN) HOT MELT,PRESSURE SENSITIVE ADHESIVES
(FR) ADHESIFS A PRESSION A CHAUD
Abstract: front page image
(EN)Blends of compatible tackifying resin with substantially amorphous olefin copolymers containing a C3 to C5 linear (Alpha)-olefin and 40 to 60 mole percent of a C6 to C10 linear (Alpha)-olefin which are useful as hot-melt, pressure-sensitive adhesives. The unmodified copolymer bases resins have melt viscosities in the range of > 75,000 cp up to 1,000,000 cp at 190 C. The addition of the compatible tackifying resins to the copolymer base resin causes an addition to improved coatability as well as substantial increases in probe tack and peel adhesion values of the copolymers.
(FR)Melanges de resine collante compatible avec des copolymeres d"olefines sensiblement amorphes contenant des (Alpha) olefines lineaires de C3 a C5 et 40 a 60% en mole d"(Alpha) olefines lineaires de C6 a C10 utilises comme adhesifs a pression sensibles a la chaleur. Les resines a base de copolymeres non modifiees ont des viscosites a l"etat fondu comprises dans une gamme allant de 75.000 cp au moins jusqu"a 1.000.000 cp a 190 C. En ajoutant des resines collantes compatibles a une base de resine copolymere, on obtient une meilleure aptitude au revetement ainsi que des augmentations sensibles des valeurs de prise et d"ecaillement des copolymeres.
