Dongying epoxy zinc rich paint steel structure antirust paint epoxy zinc rich finish
brief introduction
Epoxy zinc rich primer is a high-performance primer for anti-corrosion and rust prevention of steel structures, which has cathodic protection and corrosion inhibition
It is matched with epoxy micaceous iron paint to form a steel structure anti-corrosion paint anti-corrosion coating
Epoxy zinc rich primer is suitable for various environments, including chlorinated rubber paint, acrylic paint, fluorocarbon paint, epoxy finish paint, etc

form
Epoxy zinc rich primer is composed of epoxy resin, antirust pigment, organic solvent and zinc powder
The first component of epoxy zinc rich primer is epoxy resin and supporting products, and the second component is amine resin

characteristic:
Epoxy zinc rich primer has excellent corrosion resistance, strong adhesion, good mechanical properties, high content of zinc powder in the paint film, conductivity and cathodic protection, and excellent water resistance
It can be used as shop pre primer with a film thickness of 15 μ m——25 μ M, which will not affect the welding performance, and can also be used as antirust primer

purpose
Epoxy zinc rich primer is used as a supporting primer for heavy-duty anti-corrosion coating
It is used in mines, derricks, shipbuilding, ports and wharfs, steel structures, bridges, iron towers, oil pipelines, chemical and metallurgical steel structures and chemical equipment
It is the best primer for epoxy intermediate paint and two-component polyurethane topcoat

Construction reference
1
The surface of the coating must be free of oxide skin, rust, oil, etc

2
The substrate temperature of epoxy zinc rich primer must be more than 3 ℃ higher than the dew point
When the substrate temperature is less than 5 ℃, the paint film will not cure, so it is not suitable for construction

3
After the barrel of component A is opened, it must be stirred evenly, and then pour group B into component A according to the proportioning requirements under stirring, fully mix evenly, stand still, and after ripening for 30min, add an appropriate amount of diluent to adjust to the optimal construction viscosity of epoxy zinc rich primer

4
The paint shall be used up within 6h after mixing

5
Brush coating, air spraying and roller coating are acceptable

6
The coating process must be continuously stirred to avoid sedimentation

Painting interval:
Substrate temperature ℃   5-10  15-20  25-30
Minimum interval h  48  24  twelve
The longest interval shall not exceed 7 days
