| Material Description | KED-D001 water-based heavy-duty anti-corrosion primer is composed of inorganic graft modified water-based epoxy resin, special curing agent, ammonium sulfonate chelating agent, inorganic anti-corrosion rock flakes, etc. It is water-based and environmentally friendly, replacing epoxy zinc rich primer, inorganic zinc rich primer, and galvanized metal primer with high cost-effectiveness, heavy anti-corrosion, and long-lasting properties. It has better performance than solvent based epoxy zinc rich primer. |
| main features | Simple construction, can be sprayed or brushed with multiple construction methods |
| Water based environmental protection, no harmful substances dissolved, no heavy metals |
| Excellent corrosion resistance, film thickness of 100um, salt spray resistance up to 3000 hours. When the film thickness is the same, the salt spray anti-corrosion performance is 6 times that of traditional water-based anti-corrosion coatings and 3 times that of standard epoxy zinc rich primers |
| Easy to use, the AB component can be used for up to 5 hours after mixing |
| Quick drying, it can be dried in 20 minutes |
| Can simultaneously replace zinc rich primer and cloud iron intermediate paint, reduce the number of construction passes, improve efficiency, and save labor costs |
| Room temperature curing, no need for baking, saving energy |
| Can reduce the footprint and drying time of steel structures |

| Usage | Metal flooring sandblasting/shot blasting to Sa2.5, it is recommended to use 80-100 mesh diamond sand and ensure surface cleanliness |
| KED-D001 water-based heavy-duty anti-corrosion primer should be accurately measured and mixed thoroughly with a ratio of A: B=7:1, and stirred evenly. It can be sprayed using a regular airless sprayer, or brushed or rolled, with a film thickness of 40-50um each time. After drying, the next layer of spraying can be carried out. It can be dried at room temperature or heated to 40-50 ° C for the next construction process |
