Room temperature curing high temperature resistant 800°C anti-corrosion coating EK-D05
EK-D05 uses room-temperature-curing polysilazane as a film-forming agent, with titanium dioxide, phosphates, and inorganic silica fume as fillers. The coating can withstand temperatures exceeding 600°C, exhibits high hardness, is dense and waterproof, and is resistant to acid, salt spray, and aging.
EK-D05 Introduction:
EK-D05 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 lustrous appearance.
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, room-temperature curing product. The mixed coating should be used within 6 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 not exceeding 50µm. Otherwise, coating performance may be compromised.
Standard Application Procedure：
Surface Cleaning → Roughening → Cleaning and Blowing → EK-D05 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 300 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, the surface should be dry for 1 hour, the touch should be dry for more than 2 hours, and the actual drying time should be more than 24 hours. It can also be cured quickly by heating (keeping warm at 180℃ for 20 minutes).
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.
