Composed of epoxy resin, red lead, fillers, amines, curing agents, etc. This paint has excellent rust prevention performance, good wettability on metal surfaces, good mechanical strength after film formation, strong adhesion, rapid drying of the paint film, water resistance, and moisture resistance.
Design purpose
Suitable for steel surfaces that require strong rust resistance, such as wet (dry) gas cabinets, various storage tanks, underwater steel structures, underground pipelines, offshore mine steel structures, and industrial plant equipment and facilities.

surface treatment
The surface of the steel should be rust and oil removed, free from dust and water. Generally, a small amount of rust is allowed on the steel surface, but there should be no loose oxide skin; Special requirements for rust removal to meet the Swedish rust removal standard Sa2.5 level, or manual and power tool rust removal to reach St3 level. The surface must be free of rust, grease, water stains, and floating ash.
Construction conditions: The two component paint must be thoroughly mixed, prepared according to the specified quality ratio, and left to stand for 30 minutes for construction.
Environmental temperature: -5 ℃ -+40 ℃
Relative humidity:<85%. The surface of the object should be dry, and if there is water, the paint film is prone to blistering.
Construction should not be carried out under strong winds, heavy rain, snow, or foggy weather. In hot summer, construction should be avoided under strong sunlight.
Rear supporting coatings: C17 high chlorinated polyethylene iron red anti-corrosion primer, C181 chlorinated rubber iron red anti-corrosion primer, C18 chlorinated rubber anti-corrosion topcoat.
Packaging specifications: 20 kilograms in an 18 liter container for component A, and 4 kilograms in a 5 liter container for component B (when using, weigh the corresponding component A according to the ratio).
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
After a stage of storage, the coating will produce partial precipitation or layering. Therefore, before preparing the coating, the paint material (component A) should be stirred evenly, and then component B should be added and stirred according to the ratio.
Apply the prepared coating after it has been cured and left stationary for 30 minutes.
If the next coat is equipped with a high chloride coating, the coating only needs to be surface dried before proceeding with the next coat of paint.
The paint film contains red lead and should not be used in sealed cabins that require pyrotechnic correction to prevent lead poisoning.
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.
