20160024782 | VAPOR PERMEABLE, WATER RESISTIVE, AIR BARRIER POLYESTER MEMBRANE HAVING A POLYACRYLIC COATING WITH POROUS PRESSURE SENSITIVE ADHESIVE ADDED TO THE REAR SURFACE OF THE MEMBRANE - 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. | 01-28-2016 |
20160002914 | BUILDING MEMBRANE WITH DRAINAGE MATRIX AND HORIZONTAL ADHESIVE PORTIONS - A building wrap membrane comprising a sheet of spunbonded polypropylene fabric member with integral adhesive attachment strips mounted on the front and back of the sheet and a drainage matrix secured to the sheet front surface 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 plurality of expansion joints formed across matrix rows. | 01-07-2016 |
20150024159 | Building membrane with porous pressure sensitive adhesive - A breathable 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 inch | 01-22-2015 |
