It is prepared from hydroxyl containing resin, polyisocyanate prepolymer, pigments and fillers, additives, solvents, etc., and packaged in two components: A and B. The paint film is resistant to various crude oil products such as crude oil, aviation kerosene, 40 # engine oil, 120 # gasoline, kerosene, diesel, benzene, etc., and has no impact on the quality of the oil (gum ≤ 7mg/100mg). The paint film has excellent anti-corrosion performance and physical and mechanical properties.

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.
Front matching coating: C0417 two component polyurethane iron red rust resistant paint
Suggested number of coats: 2-3 coats, with a dry film of 70-100 μ M.
Packaging specifications: 18 kilograms in a 20 liter container for component A, and 4.5 kilograms in a 5 liter container for component B.
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.
After coating, the paint film of this product can fully cure at room temperature for seven days before being delivered for use.
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.
