ABSTRACT:
An anti-fracture, water-resistant, masonry-bondable membrane comprises a laminate having a core generally containing at least two plies of a flexible material bonded together by a flexible adhesive such as a plastisol, and a non-woven fiber layer physically bonded directly to at least one side of the core. The plastisol is a liquid composition which contains small sized resin particles such as polyvinyl chloride dispersed within a plasticizer. The core has good low as well as high temperature peel strength. The non-woven fiber layer is physically bonded to the flexible core by heat and pressure to produce a laminate wherein the non-woven fibers are partially embedded within the flexible material. The flexible membrane or laminate when utilized between and bonded to an exterior masonry article such as ceramic tile and to a substrate such as concrete, is very effective in preventing any cracks from propagating from the substrate to the article.
