    摘要: Upon grinding a back of a substrate, a protecting tape made of a material soluble to IPA (isopropanol), for example, a vinyl acetate thermoplastic adhesive is appended on the surface of a pattern-formed layer of a wafer, grinding the back, dipping the wafer in a cleaning vessel containing IPA, and dissolving and removing the protecting tape from the wafer, thereby giving no damages to the wafer, and reducing the number of operation steps.

    摘要: An adhesive composition containing a polyvinyl alcohol-stabilized butadiene polymer latex and a methylene donor compound. The butadiene polymer latex is prepared by an emulsion polymerization in the presence of polyvinyl alcohol. The adhesive composition may also contain other optional ingredients such as a supplemental polymeric film-forming component, a nitroso compound crosslinker, a maleimide compound crosslinker, a vulcanizing agent, and an acid-scavenging compound. The polyvinyl alcohol-stabilized butadiene polymer latex and methylene donor compound combine to provide a tightly crosslinked, robust film which provides for excellent adhesion and environmental resistance.

    摘要: Heat-vulcanizable adhesives for the bonding of solids, the adhesive contains polybutadiene or a polybutadiene mixture and/or copolymers of butadiene with ethylenically unsaturated monomers and other vulcanizable components, and at least 0.5% by weight (based on the weight of vulcanizable components) of a metal salt as a hardening catalyst. The adhesive is particularly useful in vehicle assembly. The adhesive in less than 5 hours exposure to air forms a protective skin which imparts washer resistance to the adhesive.
