Product characteristics

• Corrosion protection and cathodic protection. Inorganic zinc-rich primers have a high zinc powder content, which gives them excellent corrosion resistance and cathodic protection. According to the principle of electrochemistry, zinc as the anode will preferentially corrode, thus protecting the steel substrate as the cathode from corrosion. This cathodic protection property is particularly important to prevent steel structures from rusting in harsh environments.
• Weather resistance. Inorganic zinc-rich primers have excellent weather resistance and are able to withstand long-term wind erosion, UV exposure, and other natural environmental factors. Even after many years of wind and sun, the paint film will not age and deteriorate, and the thickness will not be thinned. In fact, the longer the exposure time, the densification and cohesion strength of the paint film will gradually increase, thus enhancing its impermeable shielding performance.
• High temperature resistance. Inorganic zinc-rich primer can withstand heat up to 400 ° C for a long time without a top coat.
• Resistance to solvents and salt spray. Inorganic zinc-rich primers are not only resistant to solvents, but also have excellent salt spray resistance. This makes it particularly suitable for use in more corrosive places such as Marine environments and chemical plants.

Technical Requirements

Product use

• Marine engineering. Inorganic zinc-rich primers are widely used in Marine engineering, especially in areas such as ships, offshore platforms and port facilities. Due to the presence of salt spray, humidity and microorganisms in the Marine environment, the requirements for anti-corrosion coatings are very high. The cathodic protection and weather resistance of inorganic zinc-rich primers make them ideal for Marine engineering.
• Petrochemicals. In the petrochemical industry, inorganic zinc-rich primers are used to protect the inner and outer walls of storage tanks, pipes, and equipment. Although there may be some limitations in some acidic environments, inorganic zinc-rich primers still show good application results in the inner walls of most neutral chemicals, solvents and refined oil storage tanks.
• Electric power industry. Applications of inorganic zinc-rich primers in the power industry include chimneys, cooling towers and other steel-framed facilities in power plants. These facilities are often exposed to harsh environments and require a paint that can resist heat, moisture, and chemical corrosion. The high temperature resistance of inorganic zinc-rich primers (long-term heat resistance up to 400 ° C without a topcoat) makes them ideal for these applications.
• Transportation. In the transportation sector, inorganic zinc-rich primers are used for the corrosion protection of Bridges, railroad cars, and automobile chassis. These parts are often exposed to various weather conditions and are susceptible to corrosion. The weather resistance and impermeable shielding properties of inorganic zinc-rich primers ensure the long-term protection of these structures.
• A construction Project. In construction engineering, inorganic zinc-rich primers can be used on the exterior walls and roofs of steel structure buildings. Not only does it provide corrosion protection, it also has fire resistance properties. In addition, the environmental properties of inorganic zinc-rich primers (zero VOC) meet the standards of modern green buildings.
• Machine building. In the field of machine building, inorganic zinc-rich primers are used for the corrosion protection of heavy machinery equipment, mining machinery and agricultural machinery. These devices often operate in harsh working environments and require a paint that can provide lasting protection. The wear and chemical resistance of inorganic zinc-rich primers make them ideal for these applications.

Supporting scheme:

• Inorganic zinc-rich primer + silicone high temperature resistant intermediate paint/epoxy cloud iron intermediate paint/epoxy thick paste intermediate paint + silicone high temperature resistant top paint/acrylic polyurethane top paint/polyurethane top paint/polysiloxane top paint/fluorocarbon top paint/epoxy top paint/alkyd top paint/graphene top paint/chlorinated rubber top paint, etc

Construction notes:

• This product is like most zinc-rich paints, long-term exposure to the paint film will appear zinc salt, must be thoroughly cleaned before applying the next paint, otherwise it will affect the adhesion between layers.
• The temperature of the substrate must be above 3 ° C above the dew point, and when the temperature of the substrate is below 5 ° C, the paint film is not cured and should not be constructed.
• In the high temperature season construction, easy to occur dry spray, in order to avoid dry spray can be adjusted to dry spray until the diluent.
• This product should be used by professional painting operators according to the product packaging or the instructions in this manual.

Steel surface:

• Must thoroughly remove oil, rust, etc., to achieve the rust removal standard Sa2.5, the roughness of 30um-75um; Adopt manual rust removal method, need to reach the rust removal standard St3 level.

Concrete surface:

• The surface of the concrete should be flat, dry, no seepage floating water and water. The base that has been polluted by grease and chemicals can be washed with detergent, lye or solvent, and can also be treated by fire baking, steam blowing, etc., but it must not damage the base.

Precautions

• Products should be stored in a cool and ventilated place to prevent rain, direct sunlight, avoid collision, need to isolate the fire source.
• The construction site is strictly prohibited fireworks, painters should wear glasses, gloves, masks, etc., to avoid skin contact and inhalation of paint mist.
• All work on the coating and use of this product must be done in accordance with various relevant national health, safety and environmental regulations and standards.
• If you have any questions about the use of this product, please contact our technical service department.
