Construction instructions
Mixing ratio base material: curing agent = 83 ∶ 17 (weight ratio ) base material: curing agent = 75 ∶ 25 (volume ratio )
Pot life after mixing at 10 °C: 6 Hours, 23 °C: 4 Hours, 30 °C: 3 Hour
Airless spray nozzle pressure : 18-25 MPa
Nozzle aperture : 0.41-0.58 mm
Spraying angle : 40-80 Spend
Dilution ratio: 0-5% (volume ratio)
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: 0-10%
Thinner / Cleaning Agent 603 Epoxy Thinner
It is recommended to add an appropriate amount of diluent after mixing components A and B of the paint evenly.
Avoid adding excessive amounts of thinner, which 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 ( Single component ) | longest ( two components ) | ||||
10 ℃ | 6 hours | 24 hours | 8 days | 18 hours | 24 hours | 14 days |
23 ℃ | 3 hours | 20 hours | 5 days | 15 hours | 20 hours | 10 days |
30 ℃ | 1 hour | 16 hours | 3 days | 12 hours | 16 hours | 7 days |
(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
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 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 confined spaces, adequate ventilation should 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.
Recommended Package
The following are typical high-performance coating systems:TO2.16 Modified epoxy primer 2 × 125μm (dry film thickness ) Subsequent coatings can be epoxy , polyurethane series products or additional coatings as specified .
Store
Must be stored in accordance with national regulations. The storage environment should be dry, cool, well-ventilated, avoid high temperatures and stay away from fire. The packaging container must be kept sealed. The storage validity period is at least 12 months.
