Thin layer of heavy anti-corrosion coating EK-D12

EK-D12 Introduction:

EK-D12 is a heavy-duty corrosion-resistant coating that is resistant to high and low temperatures and hydrofluoric acid. It is a one-component, semi-permanent, and novel corrosion-resistant coating.

Compared to traditional coatings, it offers many unique properties, including heavy-duty corrosion protection, high and low temperature resistance, wear resistance, impact resistance, and insulation (the film exhibits insulating properties). Its main chain segment utilizes a fluorosilicone polymer, partially end-capped with isocyanate NCO reactive groups, and also coated with reactive groups.

During use, the presence of oxygen in the air releases the reactive groups, allowing them to form stronger chemical bonds with the polar surface of the protected material, self-extending and cross-linking, thereby forming an interpenetrating polymer network (PIN).

Due to its low viscosity in the initial low molecular weight phase, it can penetrate the protected material and fill surface pits, achieving a strong bond between the anti-corrosion material and the protected material, ultimately forming an airtight, dense surface layer. This effectively prevents oxygen and moisture from reaching the protected surface, thereby achieving its corrosion protection goal.

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 caking. It is recommended that the coating be applied in one coat, with a dry film thickness not exceeding 200µm. Otherwise, coating performance may be compromised.

Standard Application Procedure：

Surface Cleaning → Roughening → Cleaning and Blowing → EK-D12 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: Curing time is closely related to thickness, curing temperature, and air speed. For a given thickness and air speed, the approximate relationship between surface-drying time and temperature is as follows:
At room temperature and humidity (20±15°C, 65±20% relative humidity), without the addition of a curing agent, the corresponding surface-drying time is approximately 6 hours; at 30°C, approximately 5 hours.
At 40°C, approximately 4 hours.
At 50°C, approximately 3 hours.
(Note: When the surface-drying time is less than 3 hours, the risk of poor quality increases. Additionally, the gradient of the heating curve should be carefully considered; applying high temperatures directly after application can affect coating quality.)

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.
