High temperature resistant 1000°C anti-corrosion nano ceramic coating EK-D03
EK-D03 uses polysilazane as a film-forming agent, with titanium dioxide, phosphate, and inorganic silica powder as fillers. The coating can withstand temperatures up to 600°C without yellowing, boasts high hardness, is dense and waterproof, and is resistant to acid, salt spray, and aging.
EK-D03 Introduction:
EK-D03 As organic-inorganic hybrid high-temperature-resistant coating, this product incorporates a variety of composite materials, including high-temperature molecular materials, anti-rust fillers, ultrafine powders, and organic polymer dispersions.
After curing, the particles are tightly packed with the resin, resulting in a high-gloss finish.
The raw materials are primarily ionic compounds, which form covalent bonds with the substrate upon curing, chemically bonding and significantly enhancing the coating’s mechanical strength.
Applicable substrates:
1. Electric heaters, boiler components, pipes, valves, heat exchangers, radiators.
2. High-temperature devices and sensor components.
3. Metallurgical equipment surfaces, automotive brake pads, mold surfaces, and casting equipment surfaces.
4. Electric heating elements, tanks, and boxes.
5. Small appliances, kitchenware (fire covers, rice cookers), etc.
6. Chemical and metallurgical high-temperature components.
Applicable temperature:
The maximum temperature resistance is 800°C, and it can be used for extended periods at temperatures up to 600°C.
It is resistant to flames and high-temperature airflow.
Depending on the substrate’s heat resistance, the coating’s heat resistance will vary. It also resists thermal shock and cold shock .
(Note: Different substrates may have different product specifications).

Special Note:
This product is a two-component, heat-curing product. Please use the mixed coating within 12 hours. During extended application periods, tools should be cleaned to prevent them from caking. It is recommended that the coating be applied in one coat, with a dry film thickness of no more than 30µm. Otherwise, coating performance may be compromised.
Standard Application Procedure：
Surface Cleaning → Roughening → Cleaning and Blowing → EK-D03 Treatment → Curing
Process Description:
1. Roughening: Before coating, polish or sandblast the substrate surface to remove rust, dust, and dirt adhering to the surface. Roughening significantly affects the coating quality. Ideally, Sa2.5 and St3 grades should be free of scale (GB/T 30790.4-2014), so please pay close attention.
2. Cleaning: Use a dedicated cleaning agent or degreasing agent to remove any remaining oil, dust, and other contaminants on the roughened surface.
3. Substrate Drying: Before coating, ensure the substrate surface is dry and clean.
4. Paint Mixing: This product has two components. Take an appropriate amount of paint according to the ratio and stir thoroughly to mix evenly. Filter through 150 mesh for later use.
5. Paint Application: Laboratory spraying with a 1.0-caliber spray gun provides optimal appearance and uniformity. The cured coating exhibits a certain degree of hydrophobicity and oleophobicity, so re-application is not recommended.
6. Curing: After spraying, allow the surface to dry for 10 minutes, then heat-cure at 180°C for 60 minutes (for coatings below 400°C), or heat-cure at 250°C for 60 minutes (for coatings above 400°C).
Product Storage:
1. Storage must comply with national regulations. The storage environment should be dry, cool, well-ventilated, and away from heat and ignition sources. The packaging container must be kept tightly closed and carefully stored.
2. The storage temperature should be maintained between 5°C and 30°C. The shelf life is 6 months.
3. Opened but unused paint must be sealed and stored.
4. Mixed but unused paint cannot be recycled and must be disposed of in accordance with local regulations.
5. Products that have exceeded their expiration date may only be used after passing testing.
