Avoid adding excessive thinner, otherwise it will reduce its anti-sagging and gloss of the coating.
Drying time and time between recoating (1)
Substrate temperature | Dry time | Working time | Recoating interval (2) | |
Shortest | longest | |||
10 ℃ | 4 hours | 8 hours | 24 hours | No restrictions |
23 ℃ | 2 hours | 6 hours | 18 hours | No restrictions |
30 ℃ | 1 hour | 4 hours | 12 hours | No restrictions |
(1)The data is for reference only. The actual drying time and recoating interval depend on factors such as paint dry film thickness, ventilation, humidity and previous paint.
(2)The surface must be dry and free of dirt before recoating. Adhesion is best when the previous coating is completely dry before applying the subsequent coating. If the coating is exposed for a long time, the surface must be roughened before recoating to ensure adhesion between the coatings.
Surface treatment
Steel SSPC-SP1 According to the regulations , use solvent to remove all grease on the surface ; remove surface welding residues and grind welds and sharp edges with appropriate methods ; sandblast until Sa2.5 Level ( ISO 8501:1 ). The steel surface should be painted immediately after being sandblasted to the specified requirements .
Repairing the corroded part must first be polished with electric tools until St3 Grade or sandblasting to Sa2 or better
( ISO8501:1 ), the surface must be dry before overcoating and free of loose coatings, salt, grease and other contaminants.
Construction conditions
The surface temperature of the substrate should be at least 3 °C higher than the air dew point temperature, and the relative humidity should not exceed 85% (the temperature and relative humidity should be measured near the substrate).
The surface temperature of the substrate should not exceed 40°C . Otherwise, a suitable spraying method should be selected and appropriate diluent should be added as required to prevent dry spraying. In extreme cases, the dry film thickness of the coating can be appropriately reduced to prevent sagging.
When painting in a confined space, proper ventilation should be provided to ensure the paint film cures. The paint temperature must be above 15 °C, otherwise thinner should be added to achieve the required viscosity for construction.
Recommended Package
The following are typical high-performance coating systems:
