This specification covers a hot melt adhesive suitable for bonding carpet, cloth, various plastics (excl
2、uding polypropylene and polyethylene) to other plastics, painted metal, or to glass. The adhesive, a 100% solids material, is applied like a conventional hot melt adhesive. After cooling, the adhesive undergoes moisture curing (x-linking) through exposure to moisture in the surrounding area. TABLE 1
