Usage recommendations:
, interior wall coating:
Add nano-titanium dioxide which is % by weight of the emulsion into the color paste raw material, stir it at high speed, then sand it into a sand mill to make the color paste. . Then add the color paste into the paint tank, add the emulsion, and stir to make interior wall latex paint.
, Exterior wall coating:
Nano-titanium dioxide is mixed with other raw materials according to the ratio of emulsion weight % and sanded to prepare pigments. Then, the pigment and the emulsion are thoroughly mixed in an emulsifier, and the paint is mixed to prepare an exterior wall paint.
Performance test of the finished paint:
Use an electric paint film adhesion tester to measure the adhesion of the paint: Nano-titanium dioxide has a great influence on the adhesion of the paint. Nano-titanium dioxide is the film-forming agent of the paint. It is an important raw material because it has excess surface free energy and good dispersion, which makes the bonding force between the substrate and the ground material strong and uniform during film formation.
Use a putty flexibility tester to measure the flexibility of the coating: When % of nano-titanium dioxide is added, the coating has the best flexibility. After surface treatment of nano-titanium dioxide, a good interface is formed between the surface and the matrix. A bonded, flexible interface layer that imparts flexibility and stress transfer capabilities to the substrate, thereby increasing the flexibility of the coating.
Use a paint film impactor to measure the impact resistance of coatings: Nano-titanium dioxide can improve the impact resistance of coatings to the highest level. Nano-titanium dioxide after surface treatment reduces agglomeration and is conducive to interfacial adhesion, thereby improving the strength of polymer coatings.
Use non-metallic materials manually and aging test equipment to measure the anti-aging performance of the coating. Conditions: aging time, aging light temperature ℃. The anti-aging properties of nano-titanium dioxide have been greatly improved.
Adding % nano-titanium dioxide, the various properties of interior and exterior wall coatings are significantly improved:
Adhesion: from grade to grade
Flexibility: from improvement to
Impact resistance: From increased to
Anti-aging time: from increased to
