Abstract:
A highly water resistant coating is described for use as a temporary protective or tinting finish for a wide variety of personal items, including one's vehicle and tires. The film forming polymer of the coating is desirable as it can be applied with polar solvent(s) but then upon evaporation of a solubilizing additive becomes water resistant or water proof. Thereafter if a similar solubilizing additive is used in a polar solvent(s), the coating can be removed without damaging the surface of the substrate.
Abstract:
The present invention is directed a rheology control additive for solvent based coating and ink formulations comprising an overbased carboxylate or sulfonate in combination with a hydrocarbyl succinic anhydride based dispersant. The combination of dispersant with carboxylate or sulfonate offe rs proportionately less viscosity decrease at elevated temperatures and control of viscosity under various shear rates.
