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.
