Product Applications

Main Performance Indicators

Substrate Treatment

1. The substrate needs to be treated by grinding, sandblasting, shot blasting and other methods.
2. For concrete, the loose part on the surface should be removed to expose the solid substrate. 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, sandblasting or shot blasting to Sa2.5 level is required. 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 more than 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 entering and affecting the density of the coating.
