ABSTRACT:
Solvent-free hot melt compositions for use as sealants, adhesives, caulking compounds or the like are produced by intimately blending elastomeric polymers with tackifying resins and plasticizers to obtain products having a hardness at room temperature of at least about 5 on the Shore A Durometer scale while being sufficiently soft at temperatures of about 50.degree.F or higher to permit them to be easily extruded or otherwise applied. Adhesion promoters, lubricants, fillers and the like are preferably added to the composition to improve the properties thereof. The products are characterized by their stability over a wide range of temperatures, their resistance to oxidation and weathering, and their low moisture vapor transmission properites.
