ADHESIVE HAVING WATER VAPOUR BARRIER PROPERTIES COMPRISING INCIPIENTLY POLYMERIZED EPOXY SYRUP

摘要

An adhesive having water vapor barrier properties, comprising an adhesive base comprised of
at least one epoxy syrupat least one elastomerat least one initiatoroptionally at least one tackifier resin andoptionally at least one further reactive resin and;optionally a solvent,;wherein the adhesive base without solvent has a water vapor permeation rate after activation of the reactive resin component of less than 100 g/m2d, preferably of less than 60 g/m2d, in particular less than 30 g/m2d, wherein the epoxy syrup comprises bisepoxy monomers and high molecular weight uncrosslinked polyepoxies produced therefrom, exhibits good barrier properties and is also sufficiently pressure sensitive to achieve easy handleability.
