Abstract
A curable composition useful in water-based paints comprises a water-based product obtained by dispersing or dissolving in water a vinyl polymer (II) containing tertiary amino and/or acidic groups which have been neutralized by an acidic or basic compound, an epoxy and hydrolysable silyl groups-containing compound (B), and a hydrolysable silyl and/or silanol groups-containing compound (F).
Claims10
A curable resin composition for use in water based paints comprising;
- a water based product (C) obtained by dispersing or dissolving in water, a vinyl polymer (II) containing both tertiary amino and acidic functionalities to which has been added sufficient acidic compound so that the molar ratio of acidic functionalities in the added acidic compound to the tertiary amino functionalities in the vinyl polymer (II) is at least 0.1,
- 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).
A curable resin composition for use in water based paints comprising;
- a water based product (D) obtained by dispersing or dissolving in water, a vinyl polymer (II) containing both tertiary amino and acidic functionalities to which has been added sufficient basic compound so that the molar ratio of basic functionalities in the added basic compound to acidic functionalities in the vinyl polymer (II) is at least 0.1,
- 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).
