Abstract
Compositions for hardening paint, particularly residual waste water-based paints are described. The compositions comprise at least one water soluble or water dispersible, natural or synthetic polymer and optionally an agent that increases the ionic strength of the paint. Methods of hardening waste water-based paint for environmentally responsible disposal are also described.
Claims19
A composition for hardening water-based paint comprising:
- i) an agent that increases the ionic strength of the water-based paint to be hardened;
- and
- ii) at least one water soluble or water dispersible, natural or synthetic polymer.
A method of hardening water-based paint comprising the steps of:
- (i) providing waste water-based paint;
- (ii) adding a composition comprising:
- (a) an agent that increases the ionic strength of the waste water-based paint;
- and
- (b) at least one water soluble or water dispersible, natural or synthetic polymer;
- and
- (iii) mixing the waste water-based paint and the composition and allowing the resulting paint composition to harden.
A method of hardening water-based paint comprising the steps of:
- (i) providing waste water-based paint;
- (ii) adding at least one water soluble, water dispersible, natural or synthetic polymer;
- (iii) mixing the waste water-based paint and the at least one water soluble, water dispersible, natural or synthetic polymer and allowing the resulting paint composition to harden.
A method of disposing of residual waste water-based paint comprising the steps of:
- (i) hardening residual water-based paint with a composition comprising:
- (a) an agent that increases the ionic strength of the waste water-based paint;
- and
- (b) at least one water soluble or water dispersible, natural or synthetic polymer;
- and
- (ii) disposing of the hardened residual paint.
A method of disposing of residual waste water-based paint comprising of the steps of:
- (i) hardening residual water-based paint with at least one water soluble, water dispersible, natural or synthetic polymer;
- and
- (ii) disposing of the hardened residual paint.
