Abstract
An adhesive composition formed by admixing under melt conditions (a) 50-95% by weight of a moisture cross-linkable silane-grafted polyolefin having a melt viscosity of less than 100,000 cps, and (b) 5-50% by weight of a polyolefin grafted with at least one ethylenically-unsaturated carboxylic acid or anhydride, and derivatives thereof. The grafted polyolefin has a melt viscosity of less than 100,000 cps, and contains a catalyst for moisture cross-linking of the silane-grafted polyolefin of (a). The adhesive may be used to bond a variety of substrates.
