Construction parameters
- Recommended film thickness: 60-80um
- Theoretical dosage: about 115g/m² (based on 35um dry film, excluding loss).
- Suggested number of coats: 2~3 coats
- Storage temperature：-10~40℃
- Construction temperature：5～40℃
- Trial period: 6h
- Construction method: Brushing, air spraying, rolling can be used.
- Painting interval ：
Substrate temperature ℃ 5-10 15-20 25-30
Shorter interval h48, 24, 12
Longer interval not more than 7 days. - The temperature of the substrate must be higher than the dew point of more than 3 ℃, when the temperature of the substrate is lower than 5 ℃, the paint film is not cured, and should not be constructed.
Painting construction
- After opening the barrel of component A, it must be stirred well, and then pour group B into component A under stirring according to the proportioning requirements, mix well and leave it to mature 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.
