Abstract: An ultra violet stable polyester membrane with a polyacrylic coating on one side and a coated pressure sensitive adhesive coating on its other side capable of allowing water vapor to pass through it. The pressure sensitive adhesive is formed of a copolymer comprising a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with at least one surfactant and emulsified to produce air bubbles which form pores when the copolymer is set with about 80% to about 90% of the pore sizes ranging from about 200 microns to about 300 microns and being uniformly distributed to form a flow path through the pressure sensitive adhesive.

Abstract: The present invention relates to a water resistant, UV resistant, vapor permeable, air barrier underlayment assembly comprising a substrate of permeable polyester, a permeable copolymer acrylate coating bonded to a permeable polyester substrate and a pressure sensitive permeable copolymer adhesive secured to the permeable acrylate coating. The underlayment is resistant to water and direct ultra-violet (UV) light for a period up to at least one year prior to coverage by cladding.
Abstract: A building wrap membrane comprising a sheet of spunbonded polypropylene fabric member with integral pressure sensitive permeable adhesive coated on the back of the member and a drainage matrix secured to the front surface of the member, the drainage matrix being comprised of individual thermoplastic threads randomly laid down to form a net and secured together by heat bonding with the threads formed into spaced rows with a channel therebetween.

Abstract: A breatheable multilayer spun bonded polypropylene membrane having a coated pressure sensitive adhesive capable of allowing air and moisture vapor to pass through it. The adhesive is formed of a copolymer comprising a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with a surfactant and emulsified to produce bubbles which form pores when the copolymer is set with about 80% to about 90% of the pore sizes ranging from about 200 microns to about 300 microns and a pore density in the cured pressure sensitive adhesive ranging from about 4200 per inch2 to about 4600 per inch2, said pores being uniformly distributed to form a flow path through adhesive.
