Composed of alkyl ester, organic silicone resin, ultrafine zinc powder, special temperature and corrosion resistant pigments, additives, curing agents, etc., both the base and topcoat are packaged in two components, A and B. Has excellent heat resistance, resistance to sudden temperature changes, and can withstand high temperatures of 250 ℃ for a long time; And it has excellent corrosion resistance, chemical atmosphere resistance, weather aging resistance, water resistance, moisture resistance, and electrical insulation. It can self dry and solidify at room temperature, dry quickly, and is convenient for construction.
Design purpose
Used as a marking paint for steel chimneys and metal surfaces that require high temperature resistance.

surface treatment
The surface of new steel must be treated with shot blasting or sandblasting to meet the Swedish rust removal standard Sa2.5 level, with a roughness of 40-70 μ M;
The surface of the maintenance project can be manually and mechanically derusted, meeting the Swedish derusting standard St3 level, with a roughness of up to 40 μ Above m.
Construction conditions: The substrate temperature must be 3 ℃ above the dew point, the relative humidity must be greater than 50%, and the topcoat must be less than 85%.
Packaging specifications
Primer: 30 kilograms in a 20 liter container for component A, 7.5 kilograms in a 10 liter container for component B;
Topcoat: 20 kilograms in a 20 liter container for component A, 0.4 kilograms in a 1 liter container for component B;
matters needing attention
The curing agent should be sealed and stored immediately after use to prevent failure;
When the coating interval between the primer and topcoat is long, the zinc salt must be removed before recoating.
During construction during high temperature seasons, in order to prevent dry spraying of the primer, a certain amount of diluent (not exceeding 30% of the total paint amount) must be added until no dry spraying occurs.
security
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.
