Product Uses

Main Performance Indicators

Substrate Treatment

1. Substrates need to be treated by grinding, sandblasting, shot blasting, etc.
2. For concrete, the loose part on the surface needs to be removed to expose the solid substrate. There should be no moisture or standing water. Special repair putty is used to fill the holes, and the corresponding primer is applied.
3. For steel substrates, sandblast or shot blast to Sa2.5 grade, remove dust, and then apply the corresponding primer.
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 compactness of the coating.
