Abstract
Pressure-sensitive adhesive composition, sheet material coated therewith, and a kit for installing insulation around windows comprising the coated sheet material. The adhesive composition consists essentially of a first component consisting essentially of a tackified, emulsifiable adhesive and a second component consisting essentially of at least one terminally unsaturated vinyl monomer, at least one vinyl-unsaturated, homopolymerizable, emulsifier monomer, and, optionally a small amount of an external emulsifier. The adhesive provides high tack and excellent adhesion at both low temperatures and high temperatures, thus rendering it suitable for outdoor use in areas that encounter extremes of weather.
