Preformed resinous coverings adhered to architectural surfaces
Abstract
Abstract A RESINOUS COVERING MATERIAL IS ADHERED TO A SURFACE WITH A PRESSURE-SENSITIVE WHICH, UPON CONTACT AFTER DRYING, DEVELOPS AN IMMEDIATE BOND OF HIGH COHESIVE STRENGTH BETWEEN THE SURFACE AND THE COVERING THAT BECOMES A PERMANENT MOISTURE-RESISTANT BOND. THE ADHESIVE COMPOSITIONS COMPRISE A LATEX AND A TRANSIENT TACKIFIER WHICH COMPRISES AN EPOXY RESIN AND A CURING AGENT. SOME ADHESIVE COMPOSITIONS MAY BE FOAMED TO PROVIDE A CONFORMABLE SMOOTH SUPPORTING SURFACE FOR A HIGH MODULUS PREFORMED RESINOUS COVERING. THE ARCHITECTURAL SURFACE, PREFORMED RESINOUS COVERING AND PRESSURE-SENSITIVE ADHESIVE CONTAINING A TRANSIENT TACKIFIER COMPRISE A USED ARCHITECTURAL SURFACE COMPOSITE FOR RESIDENTIAL AND COMMERCIAL INSTALLATIONS.
