| Storage stability |
12 months (less than 30℃ environment). Re-test after expiration. If it meets the requirements, it can be used at will. |
| Curing process |
200℃/12min, 180℃/15min (workpiece surface temperature). |
| Pretreatment |
All metal substrates need to be degreased and degreased, iron metals are treated with zinc or iron phosphating and aluminum chromium to improve corrosion resistance. |
| Coating |
- Manual or automatic spraying equipment can be used. To ensure the consistency of the coating, automatic spraying equipment is recommended.
- Unsprayed powder can be recycled through an appropriate recycling system.
- Atomizing air pressure ∽0.5 bar Primary air ∽0.5 bar, spraying voltage 40-90kv.
|
| Damage repair |
Surface treatment: Grinding + air cleaning.
Application: Recoating mode,reduce spraying voltage.
|
| Safety Warning |
- When spraying, do not eat, drink or smoke, and avoid inhalation of dust.
- Wear a suitable breathing mask.
- For more information, please ask the salesperson for the material safety data sheet of the specific product for reference.
