AQUEOUS MULTIPHASE DISPERSIONS FOR MULTICOLOUR COATINGS

Aqueous multiphase dispersions for multicolour coatings are produced by a process essentially comprising the steps of: - providing one or more emulsion paints; - adding at least one linear colloid capable of being insolubilised by borate ions and at least one hydrophilic inorganic clay to said paint...

Beschreibung
Zusammenfassung:	Aqueous multiphase dispersions for multicolour coatings are produced by a process essentially comprising the steps of: - providing one or more emulsion paints; - adding at least one linear colloid capable of being insolubilised by borate ions and at least one hydrophilic inorganic clay to said paints to form base paints; - providing an aqueous medium containing at least one hydrophilic inorganic clay; - adding said base paints into said aqueous medium; - adding borate ions to said aqueous medium; - adding at least one emulsified binder to said medium; each of the emulsion paints having a different colour. It is preferred to use galactomannoglycans as colloid (most preferably guar gum) and synthetic clays (most preferably of the smectite or hectorite types).
