Room temperature thin layer anti-rust coating EK-D11

EK-D11 Introduction:

EK-D11 uses a room-temperature-curing epoxy-modified polysilazane as a film-forming agent, along with pigments, zinc phosphate, and inorganic silica fume as fillers. Compared to traditional heavy-duty anti-corrosion coatings, it boasts ease of application, one-step film formation, and a lightweight, thin coating.
The coating withstands temperatures exceeding 200°C for extended periods, exhibiting high hardness, a dense surface, waterproofing, anti-rusting properties, acid and salt spray corrosion resistance, and weather and aging resistance. As a novel organic-inorganic hybrid high-temperature anti-corrosion 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 glossy appearance. Furthermore, the cured film-forming agent covalently bonds to the substrate, significantly enhancing the coating’s mechanical strength and adhesion.

Applicable substrates:

1. Boiler components, pipes, valves, heat exchangers, radiators, and steel structure equipment in the chemical industry;
2. Anti-corrosion and anti-rust coating for indoor and outdoor projects such as railway bridges, marine engineering, oil pipelines, metallurgical and chemical facilities, and various steel structures;
3. Anti-corrosion and anti-rust zinc coating for various welds and bolts, as well as for metallurgical and chemical iron bridge railings, greenhouses, and outdoor iron railings;
4. Small appliances and kitchenware (fire covers, rice cookers), etc.

Applicable temperature:

The maximum temperature resistance is 400°C and it can be used for a long time at 300°C.
Depending on the temperature resistance of different substrates, the temperature resistance of the coating will vary accordingly, and it is resistant to cold and hot shocks .
(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 of no more than 60µm. Otherwise, coating performance may be compromised.

Standard Application Procedure：

Surface Cleaning → Roughening → Cleaning and Blowing → EK-D11 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 150℃ 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.
