  • Adhesive composition
    Patent number: 5200458
    Abstract: An adhesive composition can be provided which comprises a vinyl acetate polymer emulsion containing acetoacetylated polyvinyl alcohol as a protective colloid and a calcium silicate alone or the calcium silicate and an isocyanate compounded therein, which can solve the disadvantages observed in the adhesives of systems in which the isocyanates are added to the emulsions like the prior art, and which retains the adhesive strength for a long time, particularly has a little reduction in initial adhesive strength, and is excellent in water resistance (water-resistant adhesion) and also in heat resistance (heat-resistant adhesion) compared to those of the prior-art adhesives.
