Product Applications

Main Performance Indicators

Substrate Treatment

1. The substrate needs to be treated by methods such as grinding, sandblasting, and shot blasting.
2. For concrete, the loose surface part should be removed to expose the solid base layer. There should be no moisture or standing water. Special repair putty should be used to fill the holes, and the corresponding primer should be painted.
3. For steel substrates, they should be sandblasted or shot blasted to Sa2.5 grade. After dust removal, the corresponding primer should be painted.
4. For the construction of other substrates, please consult the Technical Department of Wanhua Energy Conservation Company.

Construction Conditions

1. Ambient temperature range: 5 - 35°C, and the substrate temperature should be 3°C higher than the air dew point temperature.
2. Ambient humidity range: ≤80% RH, and the moisture content of the concrete base surface should be less than 6%.
3. Ventilation conditions: Ensure that there is no strong wind in the construction site to avoid dust affecting the compactness of the coating.
