Abstract
A curable resin composition of use in water-based paints comprises a water-based product obtained by dispersing or dissolving in water a vinyl polymer (II) containing tertiary amino groups, acidic groups, or both tertiary amino and acidic groups which has been either partially or completely neutralized by an acidic or basic compound, an epoxy and hydrolyzable silyl groups-containing compound (B), and a composition further containing a hydrolyzable silyl and/or silanol groups-containing compound (F).
Claims17
A curable resin composition for use in water based paints comprising:
- a water based product (E) obtained by dispersing or dissolving in water, an acidic vinyl polymer (III) which has been partially or completely neutralized by a basic compound,
- a compound (B) containing both epoxy and hydrolysable silyl functionalities, and
- a compound (F) containing a hydrolysable silyl functionality and/or a silanol functionality, but excluding the compound (B), compound (F) being a compound or a mixture of compounds selected from the group consisting of silicate compounds, trifunctional silane compounds, difunctional silane compounds, linear and cyclic polysiloxanes containing silanol functionality, and linear and cyclic polysiloxanes containing alkoxysilyl functionality, the linear and cyclic polysiloxanes containing alkoxysilyl functionality being obtained by carrying out a partial hydrolysis condensation on at least one of the compounds selected from the group consisting of the difunctional and trifunctional silane compounds and silicate compounds.
