Basic Properties
Tough film;
Good mechanical strength;
Excellent low-temperature application performance;
Excellent water resistance;
Good corrosion protection.
Recommended Uses
Can be used as an intermediate Coating for chlorinated rubber anti-corrosion systems on steel structures in moderately to severely corrosive environments (including immersion zones).
Surface Preparation
All surfaces must be clean, dry, and free of dirt. Surfaces must be assessed and prepared in accordance with ISO 8504.
Cleanliness: Sandblasted to Sa 2 1/2 (ISO 8501-1:1988).
Painted Surfaces
Clean, dry, and intact compatible primer.
Application Conditions
The substrate temperature should be at least 3°C above the air dew point. Temperature and relative humidity should be measured near the substrate. Good ventilation is usually required in confined areas to ensure proper drying.
Recommended Applications
Primer: Highly chlorosulfonated polyethylene primer
Intermediate: Highly chlorosulfonated polyethylene micaceous iron intermediate
Topcoat: Highly chlorosulfonated polyethylene Topcoat or modified one-component acrylic Topcoat
Storage
Must be stored in accordance with national regulations. The recommended storage temperature is 15-25°C. The storage environment should be dry, cool, well-ventilated, and away from heat and ignition sources. The container must be kept tightly closed. At 25°C, the product has a shelf life of at least 12 months.
Packaging
25 kg/drum.
