- Electrical tools descaling to St3 grade.
Pre-course package
- Directly painted on the steel surface whose rust removal quality reaches Sa2.5 grade.
After matching
- Polyurethane mica paint, polyurethane paint, acrylic polyurethane top coat, fluorocarbon top coat.
Construction parameters
- Recommended film thickness: 60-80um
- Theoretical dosage: about 115g/m² (based on 35um dry film, excluding loss).
- Suggested number of painting passes: 2~3 passes
- Storage temperature：-10~40℃
- Construction temperature: 5~40℃
- Trial period: 6h
- Construction method: Brushing, air spraying, rolling can be.
- Painting interval ：
Substrate temperature ℃ 5-10 15-20 25-30
Shorter interval h48 24 12
Longer interval not more than 7 days. - The substrate temperature must be higher than the dew point of more than 3 ℃, when the substrate temperature is lower than 5 ℃, the paint film is not cured, should not be constructed.
Painting construction
- After opening the barrel of component A, it must be stirred well, then pour component B into component A under stirring according to the proportioning requirements, mix well, leave it to stand still and cook for 30mins, then add appropriate amount of thinner and adjust it to the construction viscosity.
- Diluent: special diluent for polyurethane series.
- Airless spraying: Dilution amount is 0-5% (by weight ratio of paint), nozzle calibre is 0.4mm-0.5mm, spraying pressure is 20MPa-25MPa (200kg/cm²-250kg/cm²).
- Air spraying: Dilution amount is 10-15% (by weight ratio of paint), nozzle calibre is 1.5mm-2.0mm, spraying pressure is 0.3MPa-0.4MPa (3kg/cm²-4kg/cm²).
- Roller coating: Dilution amount is 5-10% (in terms of paint weight ratio).
Precautions
- In the high temperature season construction, easy to dry spray, in order to avoid dry spray can be adjusted with thinner until not dry spray.
- This product should be used by professional painting operators according to the instructions on the product package or this manual.
- All coating and use of this product must be carried out in accordance with all relevant health, safety and environmental regulations and standards.
- If you are in doubt as to whether this product should be used, please contact our technical service department for details.
