ADVANTAGE OF OUR PRODUCTS IN PAINTS:
Higher degree of whiteness and hiding power of the paint once applied (when dry). Greater development of the degree of whiteness of the white pigments used.
Cost reduction in the formula, especially when titanium dioxide is substituted. Up to 20%-30% in weight of the white pigments used can be substituted.
Increased stability of the paint during storage over long periods. It acts as an anti-settling agent and a regulatory agent of the viscosity and of the pH.
Gives exterior paints good weathering properties and reduces its tendency to dirt pick-up.
