| Résumé : |
Although pure-acryilc based coatings already exhibit a good exterior durability, there is still a need to further enhance their performance to move our industry towards improved sustainability by creating even longer lasting coatings. A new family of pure acrylic binders has been designed to adsorb onto TiO2 pigment in order to not only boost the hiding performance by better spacing the pigment, but also to help create a more homogeneous network in the final coating. The more optimal distribution of the mineral phase in the organic matrix allows for a final coating with superior performance, in particular : an excellent chalk resistance, excellent efflorescence resistance and improved gloss and color retention. The paint formulator can now develop coatings with further improved durability, reduced TiO2 level which results in formulation cost savings and better environmental profile since TiO2 is often a main negative contributor to a paint product's carbon footprint over the cradle-to-grave lifecycle. |
