Title (EN) CURABLE COMPOSITIONS AND LOW TACK, SELF-ADHERENT ADHESIVES PREPARED THEREFROM
(FR) COMPOSITIONS DURCISSABLES ET ADHÉSIFS AUTOCOLLANTS À FAIBLE PÉGOSITÉ PRÉPARÉS À PARTIR DE CELLES-CI
Abstract:
(EN) A low tack, self-adherent adhesive is obtained by curing a composition containing at least one acrylate-functionalized urethane oligomer, at least one poly(meth)acrylate- functionalized monomer and, optionally, at least one free radical initiator such as a photoinitiator or peroxide, but little or no hydrocarbon tackifying resin. Such adhesives are useful for producing reclosable packaging, wherein strips of adhesive are arranged in an opposed manner such that a package may be repeatedly opened and then resealed.
(FR) L'invention concerne un adhésif autocollant à faible pégosité qui est obtenu par durcissement d'une composition contenant au moins un oligomère d'uréthane fonctionnalisé par un acrylate, au moins un monomère fonctionnalisé par un poly(méth)acrylate et, éventuellement, au moins un initiateur de radicaux libres tel qu'un photo-initiateur ou un peroxyde, mais peu ou pas de résine hydrocarbonée donnant du collant. De tels adhésifs sont utiles pour produire un emballage refermable, des bandes d'adhésif étant agencées de manière opposée de telle sorte qu'un emballage peut être ouvert puis refermé hermétiquement de façon répétée.
