SILZ-HT23 is a high-temperature anti-corrosion nano-ceramic coating formulated with polysilazane as the primary film-forming binder. It is compounded with functional inorganic fillers including mica powder, titanium dioxide, phosphates, and inorganic silicon powders. After curing, the coating forms a dense, hard, and waterproof ceramic-like layer with excellent resistance to acids, salt spray, aging, and harsh environments.
The cured coating is capable of continuous long-term service at temperatures up to 600 °C, providing reliable protection for metal substrates exposed to severe thermal and corrosive conditions.
SILZ-HT23 is a novel organic–inorganic hybrid high-temperature coating system composed of high-temperature polymer materials, anti-corrosion pigments, ultrafine functional powders, and polymer dispersion technology. After curing, the fillers are densely packed within the polysilazane matrix, resulting in a coating with uniform appearance, moderate gloss, and no obvious macroscopic defects.
The formulation primarily utilizes ionic compounds that form covalent bonds with the substrate during curing, significantly enhancing mechanical strength and adhesion. Acid- and alkali-resistant raw materials ensure excellent chemical stability, while lamellar and rod-like filler structures improve UV resistance and crack resistance, enabling effective resistance to environmental degradation.
