  • Storage-stable, moisture curable mixtures containing mercapto-terminated liquid oligomer, liquid polymer or liquid monomer, liquid oligomer and liquid polymer, with sodium chromate
    Patent number: 4110295
    Abstract: A process for preparing a mixture capable of hardening when exposed to atmospheric moisture, but stable when stored in the absence of moisture, comprises mixing a liquid monomer, oligomer and polymer, liquid oligomer or liquid polymer having at least one terminal mercapto group with a latent hardener comprised of a paste containing anhydrous Na.sub.2 CrO.sub.4 and a water-soluble solvent, such as dimethyl formamide, dimethyl sulfoxide, methanol, ethanol, glycol, glycerine or dioxane. The resulting mixture is useful as a caulking compound.
