Mix base and hardener strictly per specified ratio, stir evenly and construct within 60 minutes after reaction standing. 2. Fully remove moisture, grease, sludge, dust, rust and corrosive salt contaminants from substrate surfaces. 3. Avoid construction when temperature below 5°C or relative humidity exceeds 85%RH; fully dry damp surfaces completely before coating. 4. Clean all coating equipment immediately after use. 5. Provide full ventilation during confined tank interior construction. 6. If recoating interval exceeds the specified limit, roughen the existing film surface to boost interlayer adhesion. 7. Long-term sunlight exposure will cause slight yellowing of film, which does not affect coating physical properties. ## Note All datasheet data are internal laboratory test results for construction reference only.
