Abstract
A shelf-stable water-borne dispersion or solution that cures rapidly and at low temperatures when coated onto a substrate can be prepared with an aqueous-based solution or stable aqueous dispersion of a polymer having a backbone containing pendant silanol groups which are sufficiently neutralized to inhibit silanol condensation.
Claims20
A latent crosslinking composition comprising a shelf-stable aqueous-based solution or dispersion of a polymer having a carbon-containing backbone attached to silanol groups which are sufficiently neutralized to inhibit silanol condensation.
A latent crosslinking composition comprising a shelf-stable aqueous-based solution or dispersion of a polymer having a backbone that contains silanetriol groups which are sufficiently neutralized to inhibit silanetriol condensation, which silanetriol groups are connected to the backbone through a secondary amine, an ether, or a sulfide group.
A latent curative comprising a stable aqueous dispersion of a polymer containing partially neutralized silanetriol groups prepared by reacting at a pH greater than 7, an alkali metal salt of 3-aminopropylsilanetriol or N-(2-aminoethyl)-3-aminopropylsilanetriol and an electrophilic polymer that contains pendant oxirane groups or pendant benzyl halide groups.
