surface treatment
The steel surface has been shot blasted or sandblasted to meet the Swedish rust removal standard Sa2.5 level, or has been derusted by hand and power tools to St3 level. The surface roughness is controlled between 40-80 μ After rust removal on the surface of steel, anti rust primer should be applied within 24 hours to avoid secondary rusting.
Construction conditions
The two component paint must be thoroughly mixed and prepared according to the specified quality ratio. It should be left to stand for 20 minutes before construction.
The substrate temperature is 3 ℃ above the dew point.
Generally, the temperature for polyurethane coating construction should be between 0-35 ℃, and attention should be paid to weather and temperature changes during construction; On rainy, foggy, snowy days, with a relative humidity greater than 85%, and during hot summer weather, construction cannot be carried out under strong direct sunlight.
Rear supporting coatings: C0419 two component polyurethane mica iron intermediate paint, C041 two component polyurethane enamel (outdoor type), CZ041 two component polyurethane topcoat (indoor type), and C0418 two component polyurethane oil resistant topcoat.
Suggested number of coats: 2 coats, with a dry film of 60-70 μ M.
Packaging specifications: 24 kilograms in an 18 liter container for component A, and 3 kilograms in a 3.7 liter container for component B.
Note: The paint film thickness can be modified according to the purpose and location of use, but this will correspondingly change the coating rate, dilution amount, drying time, and repainting interval.
matters needing attention
The optimal application conditions for this coating are temperature 0-35 ℃, relative humidity ≤ 85%, or the surface of the coating should be above the dew point temperature by more than 3 ℃. It cannot be applied under conditions of rain, fog, snow, and large dust.
This coating can be applied by spraying, brushing, roller coating, and other methods. Different construction methods have different requirements for the viscosity of the coating. Special diluents should be used to adjust the viscosity of the coating, and water, banana water, alcohol, gasoline, etc. are strictly prohibited.
Polyurethane coatings belong to the category of "chemical reactive" coatings. Before construction, they must be thoroughly stirred and mixed evenly according to the specified quality ratio. Construction can only be carried out after remaining for 20 minutes at a temperature of 25 ℃ -35 ℃ and maturing. If the temperature is below 25 ℃, the maturation time can be appropriately extended. The cured coating should be used up within 4-8 hours to avoid waste of bonding.
After the use of the coating, the packaging barrel lid must be tightly sealed, otherwise it is prone to deterioration due to the effects of moisture, alcohol, and water.
security
Please pay attention to the safety precautions on the packaging label. In addition, safety regulations stipulated by relevant national or local governments should also be followed. Avoid long-term inhalation of solvent vapors or paint mist, and do not come into contact with skin or eyes. When working in narrow or poorly ventilated areas, strong ventilation must be provided, and even if the ventilation conditions are good, protective equipment should be worn.
