|
| Interval time for recoating | One dish per day (20 ℃) |
| Supporting coatings | Epoxy, chlorinated rubber, polyurethane, acrylic and other topcoats |
| Substrate temperature | 3 ° C above dew point |
| instructions | 1. The steel plate substrate should be treated with oil and rust removal, preferably sand or shot blasting, to meet the Swedish standard Sa2.5 or St2.5 level |
| 2. The components A and B should be strictly mixed according to the prescribed ratio, and appropriate diluents should be added to adjust to the appropriate construction viscosity. It is recommended to adjust the construction viscosity for 20-25 seconds (25 ℃), stir thoroughly, and filter with a 60-80 mesh sieve. Let it stand for 10-15 minutes before construction |
| 3. After mixing two components, they should be used up within the specified time (4 hours at 30 ℃ and 6 hours at 20 ℃) |
| 4. For special areas such as corners, welds, cutting, and inadequate spraying, 1-2 coats of this coating should be applied before spraying, followed by extensive spraying to ensure the thickness of the paint film in each area |
| 5. Ensure the required thickness of the anti-corrosion paint film. If the thickness requirement cannot be met, three or four coats of spraying are required. Because sufficient thickness of rust proof paint film is the guarantee for rust and corrosion prevention of steel structures |
| coating method | Spray coating (recommended spray pressure 0.4-0.5 megapascals), roller coating, brush coating |
| thinner | Epoxy diluent |
| Storage period | Sealed storage in a cool and dry place, with a shelf life of 12 months. If it exceeds the shelf life and passes inspection, it can still be used |
