Title (EN) POSITIONABLE-REPOSITIONABLE PRESSURE-SENSITIVE ADHESIVE
(FR) ADHESIF POSITIONABLE-REPOSITIONABLE SENSIBLE A UNE PRESSION
Abstract:
(EN) A positionable-repositionable pressure-sensitive adhesive may be repeatedly applied to a surface and removed during an initial installation time period. A laminate (10) is shown comprising a substrate or carrier layer (12) secured to a pressure-sensitive adhesive layer (14). A conventional release liner (16) having a low energy surface of silicone or the like may be applied to the outer surface (14a) of the adhesive layer (14) to protect it from contamination when the laminate (10) is in sheet form or to allow the laminate to be wound in roll form. The laminate (10) may be self-wound without the use of a liner (16) depending upon the composition of the substrate layer (12).
(FR) L'adhésif positionable-repositionable sensible à une pression peut être appliqué de manière répétée sur une surface et enlevé pendant une période d'installation initiale. Un laminé (10) comprend un substrat ou une couche porteuse (12) fixée sur une couche adhésive (14) sensible à une pression. Une doublure de libération classique (16) ayant une surface en silicone de faible énergie peut être appliquée sur la surface externe (14a) de la couche adhésive (14) pour la protéger de la contamination lorsque le laminé (10) se présente sous la forme d'une feuille ou pour permettre au laminé d'être enroulé sous la forme d'un rouleau. Le laminé (10) peut être auto-enroulé sans utiliser de doublure (16), en fonction de la composition de la couche du substrat (12).
