Room temperature curing insulation voltage-resistant coating EK-D06
EK-D06 is suitable for insulation, voltage resistance, weather resistance and aging resistance protective coatings on battery compartments, energy storage cabinets, transformers and charging piles.
EK-D06 Introduction:
EK-D06 uses polysilazane as a film-forming material and can be cured at room temperature or by heat. Its dielectric strength is ≥105V/mm and it can withstand long-term use in environments of 400-500°C without cracking, peeling, or discoloration.
Its pencil hardness is ≥5H, and it exhibits excellent properties such as abrasion resistance, waterproofing, salt spray corrosion resistance, and aging resistance.
After curing, it forms a covalent bond with the substrate, significantly enhancing the coating’s mechanical strength through chemical bonding.
Applicable substrates:
1. Various insulation facilities, electric motors, electrolysis, flooring, energy storage, batteries, electric furnaces.
2. Electromagnetic induction, aerospace equipment, military equipment, high-tech equipment.
3. Electric heating equipment, power equipment, substations, converter stations, electrical equipment.
4. Heating facilities, photovoltaic facilities, thermal energy equipment, etc.
Applicable temperature:
The coating has a maximum temperature tolerance of 800°C and can be used for extended periods at temperatures between 400-500°C.
It is also resistant to short-term exposure to flames or high-temperature airflow.
The coating’s heat resistance will vary depending on the substrate’s heat resistance.
(Note: Different substrates may have different product specifications).

Special Note:
This product is a two-component, self-curing product. Please use the mixed coating within 4 hours. During extended application periods, tools should be cleaned to prevent them from caking. Repeated spraying intervals of 5-8 minutes are recommended, with each application maintaining a minimum thickness of 40µm.
Standard Application Procedure：
Surface Cleaning → Roughening → Cleaning and Blowing → EK-D06 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 180 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 30 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.
