Brush or roller coating is only recommended for pre-coating and small area coating , but the specified dry film thickness must be achieved.
Dilution ratio: 0-5%
Thinner / Cleaning Agent 603 Epoxy Thinner
It is recommended to add an appropriate amount of diluent after the paint base and curing agent components are evenly mixed.
Avoid adding excessive amounts of thinner, as this will reduce sag resistance and extend curing time.
Drying time and time between recoating (1)
Substrate temperature | Dry time | Working time | Fully cured | Recoating interval (2) | |
Shortest | longest | ||||
10 ℃ | 1 hour | 5 hours | 10 days | 4 hours | No restrictions |
23 ℃ | 30 minutes | 3 hours | 5 days | 3 hours | No restrictions |
30 ℃ | 20 minutes | 2 hours | 4 days | 2 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. The adhesion of subsequent coatings is best when the previous coating is completely cured. If the coating is exposed for a long time, the surface must be roughened before recoating to ensure adhesion between the coatings.
Surface treatment
According to SSPC-SP1 , all grease on the steel surface should be removed with solvent; welding residue on the surface should be removed and welds and sharp edges should be polished by appropriate methods; sandblasting should be performed to Sa2.5 level ( ISO 8501:1 ). After the steel surface is sandblasted to the specified requirements, it should be painted immediately.
Repairing the corroded parts must first be polished to St3 level with electric tools or sandblasted to Sa2 level 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 shall not be lower than 5 °C and at least 3 °C higher than the air dew point temperature, and the relative humidity shall not exceed 85% (the temperature and relative humidity shall 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, appropriate ventilation equipment must be provided to ensure the cure of the paint film.
After the base material and curing agent are mixed, the temperature must be higher than 15 ℃, otherwise a diluent should be added to achieve the required viscosity for construction.
