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 inch2 to about 4600 per inch 2, said pores being uniformly distributed to form a flow path through the adhesive.
Membrane de polypropylène filée-liée multicouches respirante dotée dun adhésif sensible à la pression recouvert pouvant laisser passer lair et la vapeur dhumidité. Ladhésif est fait dun copolymère comprenant une base dacrylate de butyle, dacrylate de 2-éthylhexyle et dacétate de vinyle, qui est mélangée à un surfactant et émulsifiée pour produire des bulles qui forment des pores lorsque le copolymère prend. Environ de 80 % à 90 % de la taille des pores varie denviron 200 microns à environ 300 microns et la densité poreuse de ladhésif sensible à la pression durci varie denviron 4 200 po2 à environ 4 600 po2. Lesdits pores sont répartis uniformément pour former un tracé découlement à travers ladhésif.
