Abstract
An aqueous dispersed pigmented tinting concentrate particularly useful for tinting aqueous latex paints or non-aqueous solvent paints, the tinting concentrate comprising a low molecular weight polyethylene glycol polyether vehicle having a number average molecular weight between about 200 and 700 in conjunction with at least about 2% by weight non-ionic alkyl polyglycoside surfactant based on the total weight of pigment in the tinting composition.
Claims29
An aqueous dispersed pigment concentrate tinting composition for tinting paint products, where the tinting composition contains tinting pigments and an organic vehicle for the tinting pigments, the improvement comprising:
- the organic vehicle consisting of a linear polyethylene glycol polyether having a number average molecular weight between about 190 and 700, where the vehicle is essentially free of volatile organic compounds, and where the aqueous dispersed pigment tinting composition contains at least about 2% of non-ionic alkyl glycoside surfactant based on the total weight of pigment, where the PVC (pigment-volume-content) of the tinting composition is between about 20% and 70%.
An aqueous dispersed pigment tinting composition for tinting paint products where the composition contains tinting pigments and an organic vehicle for the tinting pigments, the improvement comprising:
- the organic vehicle consisting of a polyethylene glycol polyether having a number average molecular weight between about 200 and 600, where the vehicle is essentially free of volatile organic compounds, and where the aqueous dispersed pigment tinting composition contains at least about 2% of non-ionic alkyl polyglycoside surfactant based on the total weight of pigment, where the PVC (pigment-volume-content) is between about 20% and 45%.
