This depends on the specific formulation and the target solids content. Compared to commonly used polysiloxane resins from Wacker, Evonik, Dows, Quark is very cost-competitive.

Phosphate types and calcium ion-exchanged silicas are suitable, which can effectively improve anti-corrosion performance. Conventionally, these anti-corrosive pigments are often added to the primer.

Yes, SH-217 epoxy-modified polysiloxane will be the recommended material for flooring coatings. This coating system offers short curing time, can be applied at low temperatures and high humidity. Besides, it exhibits good abrasion resistance, and excellent resistance to acids and alkalis.

For example, SH-217 (primer-topcoat-in-one) over MIO, the pull-off adhesion exceeds 8 MPa.

If polysiloxane coatings are recoated with the same coating system, the recoatability of polysiloxane is good.

Both fluorocarbon and polysiloxane have excellent weather resistance when apply in protective topcoat. But the biggest drawback of fluorocarbon is its environmental persistence. It has high fluoro content, and doesn't meet PFAS policy requirements. Quark's polysiloxane resin offers high solids/low viscosity, low VOC, is free of isocyanate, has outstanding weatherability, is safe and eco-friendly, it is the ideal selection to formulate solvent-free or high-solids coatings.
