Abstract
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 inch2, said pores being uniformly distributed to form a flow path through the adhesive.
