Coating method:
High pressure airless spraying or air spraying.
Direction for use:
- Stirred uniformly before use, in general case, do not need mix with other materials, if the viscosity is high and difficult to construct, added a small amount of water properly, stirred well before construct;
- The coating material should be degreasing, derusting, decontaminating and other treatments in accordance with national standards or industry standards before coating;
- Maintain pH 7.5-8.5;
- Do not construct when high humidity or rainy days.
Storage and transportation:
Storage time: 6 months. Store in a cool well-ventilated place, avoid sunlight, and 5℃-35℃; Avoid cold, sun exposure and rain when transporting.
