Title (EN) PRESSURE SENSITIVE ADHESIVE TAPE AND SILICONE-FREE RELEASE COATING USED THEREIN
(FR) RUBAN AUTO-ADHESIF ET REVETEMENT DE LIBERATION SANS SILICONE UTILISE DANS LEDIT RUBAN
Abstract: front page image
(EN)A pressure sensitive adhesive tape is provided having a silicone-free release layer, said tape comprising (1) at least one backing layer; (2) at least one pressure sensitive adhesive layer, and (3) at least one silicone-free release layer, said release layer comprising a crosslinked poly(alkylene oxide), said poly(alkylene oxide) being defined by the formula X1-(O-R)n-OX2 where X1 and X2 are terminal groups at least one of which permits crosslinking of said poly(alkylene oxide), n ranges from 1 to 200,000, R is a straight or branched alkylene group having the formula (CR1R2)m where m is an integer from 1 to 10 and R1 and R2 may independently be hydrogen and C1-3 alkyl.
(FR)L'invention concerne un ruban auto-adhésif comprenant une couche de revêtement de libération sans silicone. Ce ruban comprend (1) au moins une couche de renfort; (2) au moins une couche auto-adhésive et (3) au moins une couche de libération sans silicone. Cette couche de libération comprend un poly(oxyde d'alkylène) réticulé, lequel est défini par la formule X1-(O-R)n-OX2 où X1 et X2 sont des groupes terminaux dont au moins un permet la réticulation dudit poly(oxyde d'alkylène), n est compris entre 1 et 200.000, R représente un groupe alkylène linéaire ou ramifié représente par la formule (CR1R2)m où m est un entier compris entre 1 et 10, et R1 et R2 peuvent indépendamment représenter hydrogène et alkyle C1-3.
