Acrylic polysiloxane paint is a high-performance, two-component, high-solids hybrid topcoat. It complies with all current VOC regulations, and does not contain heavy metals such as lead and chromium, and does not contain isocyanates. It has excellent weather resistance, yellowing resistance and chalking resistance, which are significantly better than aliphatic polyurethane topcoat. It is widely used in marine engineering platforms, bridges, airports, stadiums and other advanced buildings.
Excellent resistance to weather and ultraviolet radiation;
Excellent resistance to acid, alkali, oil, water and contaminants;
Nontoxic and environmentally friendly;
Good gloss and color retention and high gloss decorative effect (Gloss and color retention is more than 4 times higher than that of Acrylic Polyurethane Topcoat).

Polysiloxane has excellent radiation resistance and chemical resistance, and its anti-nuclear pollution performance is also quite outstanding. Polysiloxane coatings are mainly epoxy polysiloxane coatings and acrylic polysiloxane coatings.
Their difference:
The characteristic of epoxy polysiloxane coating is its excellent corrosion resistance. It combines the properties of epoxy and polysiloxane, with resistance to minerals and organic acids, alkalis, oxidizing chemicals and aggressive solvents. Its overall chemical resistance exceeds that of MDA cured epoxy coatings and amine cured phenolic epoxy coatings.
The acrylic resin modified polysiloxane coating ensures weather resistance and improves its flexibility and recoating performance. The gloss retention of acrylic polysiloxane coatings is significantly better than that of epoxy polysiloxane coatings, especially under long-term exposure to the sun, this difference can be more obvious.
