The composition consists of epoxy resin, lyacamide resin curing agent, gray mica iron oxide, anti-rust pigments, Auxiliaries and solvents, etc..
The main characteristics of sandblasting steel have excellent adhesion; Excellent adhesion on properly treated galvanized steel and aluminum alloy; Zinc rich primers and zinc sprays of steel have excellent adhesion and closure properties; .. Good weather and corrosion resistance in industrial and chemical atmosphere; The surface has a certain degree of roughness, and it has a good matching performance with epoxy, chlorinated rubber, polyurethane surface paint, and can also be matched with traditional paint such as alkyd, phenolic, etc., and has good interlayer adhesion with the posterior paint film.
Good wear resistance; Good rust resistance and durability; Recognized by China Classification Society
The interlayer adhesion and protective properties of the whole coating are enhanced by using an intermediate coating that can be used as a high-performance rust resistant paint such as epoxy zinc primer and inorganic zinc primer. Can be used for galvanized steel, aluminum alloy surface for primer use: can also be directly painted in sandblasting treatment of steel surface for anti-rust primer use. It is widely used in heavy corrosion prevention systems for ship and land steel structures.

Surface treatment of steel coated with zinc primer: remove all oil, debris and zinc salt; Zinc plated steel: All oil, debris and zinc salts are removed by grinding with pneumatic or electric elastic grinding wheel sheets; If it is used for underwater parts, light sweeping sandblasting must be used for surface treatment; Steel: Sand blasting treatment to 2. Level 5; Covered with workshop primer steel: secondary rust removal at film damage, rust and white rust on zinc primer, removing rust and grinding to St3; Aluminum alloy: Light sweeping sand blasting is used at the bottom of the ship, and sandpaper is used to make hair on the waterline or on land; Old paint film that can be matched: hair the old paint film after removing all oily debris
The temperature of the substrate under construction conditions must be higher than 3 °C above the dew point; When the temperature of the outdoor construction substrate is below 5 °C, please use the winter type 842 epoxy anti-rust paint; Relative humidity not more than 85 %

The drying and curing time of 842 epoxy ferric antirust paint is shortened with increasing temperature. The cure time at different temperatures is as follows:
Temperature 5 °C 10 °C 15 °C 20 °C 30 °C
Dry 4h3h2 .5 h2h1h
Dry 60h48h36h24h16h
Complete cure -- 15d 10d 7D 5D
The temperature can carry out the construction of 842 epoxy ferric rust resistant paint between 5-10 °C, but the curing speed is very slow; When the temperature is below 5 °C, the reaction between epoxy resin and curing agent stops and it is not appropriate to carry out construction. In this case, construction can be carried out in a painting workshop with a temperature above 5 °C. Or use 842(winter type) epoxy cloud iron anti-rust paint; Adequate ventilation is required during the construction and curing of 842 epoxy ferric rust resistant paint; 842 Epoxy cloud iron antirust paint on the surface of the paint film is not powdered or contaminated by other substances, there is generally no limit to the longest coating interval. However, the best interlayer adhesion will be obtained by painting the paint under the paint before the film is completely cured. If the paint film of the 842 epoxy anti-rust paint is painted after a long period of exposure in the atmosphere, special attention should be paid to the cleaning of the paint surface and the removal of the powder layer by grinding to obtain good adhesion; When the paint film, such as 842, is thick, or when the relative humidity is greater than 85 % during painting, the paint film will show a smooth surface. To increase the adhesion between the film layers, sandpaper should be used before the construction of the next paint
