What are the application precautions for high-temperature and corrosion-resistant coatings?

Most people might think that paints and coatings are just for decorative purposes, but that's not the case. Modern building materials require high performance, thus there are various types of materials with fire-resistant, anti-corrosive, waterproof, and thermal insulation properties, such as high-temperature resistant anti-corrosive coatings, which possess excellent anti-corrosive characteristics and are now used in many fields. Next, let's explore the application precautions for high-temperature resistant anti-corrosive coatings with the editor.

Before application, the surface of the anti-corrosion material must be strictly treated, removing rust, oil, and other contaminants. For surfaces requiring welding for steel corrosion protection, there should be no weld spatter or sharp edges. The surface treatment should be completed within 12 hours to prevent secondary contamination.

2. The temperature should be between 5-35 degrees Celsius, with a relative humidity not exceeding 75%, or the coated surface temperature should be no more than 3 degrees above the dew point. If construction is carried out in the presence of rain, fog, snow, or dust, the product will be significantly affected.

We recommend applying the coatings through methods such as brushing, rolling, and spraying. For different application methods requiring coatings with varying viscosity for high-temperature corrosion resistance, it is essential to have different mixing ratios for various uses to achieve better effects.

4. After applying the high-temperature resistant anti-corrosion coating and allowing it to dry for 24 hours, then apply the second layer of paint. After opening the anti-corrosion coating, seal the drum lid to prevent it from being affected by moisture, alcohol, and water, which can lead to deterioration and impact its usability or render it unsuitable for use.

5. Under normal room temperature and humidity conditions, it is recommended to allow the product to dry for 7-10 minutes after installation before use for optimal performance.

6. High-temperature resistant anti-corrosion coatings are both heavy-duty corrosion protection products and hazardous materials. They should be stored in cool, well-ventilated areas, away from fire and heat sources, and fire precautions must be taken. Particularly, open flames are strictly prohibited on construction sites.

Ensure excellent ventilation at construction sites to prevent intoxication.

These are the application precautions for high-temperature and corrosion-resistant coatings. They primarily concern fundamental aspects such as surface preparation, application temperature and time, coating methods and processes, the sealing and storage of paint, as well as ventilation in the field environment. Among these, many safety operation details require our careful attention and understanding.
