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.
