Construction process:
- Brushing, spraying or dipping paint, water addition is about 20% ，the viscosity is 25-35 s, do not add water excessively;
- The surface of being painted should be cleaned, do not have oil spots and floating dust, etc;
- When coating, if there is a drying line, the film can be dried below 90℃ in order to speed up the drying, and the leveling time is no less than 15 minutes, the drying time is no less than 25 minutes;
- Before painting the second coat, the first coat should dry out, the time between the first and second coat must be over 24h;
- Do not mix with other products or organic solvents. Wash all tools with water immediately after painting to avoid hardening.
Attention:
- Diluted with water, avoid the pH is acid, when dilute, follow the principle of a small amount several times;
- The leftover paint should be stored separately, maintain pH 7.5-8.5 when reuse; 3. Do not construct when the temperature below 5 ℃ or humidity above 85%.
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.
Standard:Q/CYQ001-2007
