  • Thermally stable hot-melt adhesive composition containing polycarbonate-polydimethylsiloxane block copolymer
    Patent number: 4117027
    Abstract: An adhesive composition is disclosed comprising a silicon block copolymer and a tackifier. The adhesive is capable of forming an unexpectedly strong bond with substrates having low surface energy without having to etch the surface of the substrate. Furthermore, the adhesive has good thermooxidative and electrical properties which latter properties are unaffected by water.
