SUBSTRATES AND PRE-TREATMENT
In order to obtain optimal anti-corrosion properties, it is
recommended to apply a chemical pretreatment
prior to powder coating application.
- Ferrous metals(cold rolled steel, cast iron etc.): Iron or zinc
phosphatation
- Zinc surfaces(galvanized steel, zinc alloy) : Chromatation or zinc
phosphatation
- Aluminum alloys : Chromatation
STORAGE
- Under dry conditions ,good ventilation at a temperature not
exceeding 30 C,humidity < 60%.
- Storage period recommended should not exceed 12 months,in case
exceeding 12 months without affecting their free flowing
properties, the powder will still have optimal characteristics.
- Should be protected from excessive heat,humidity,water and
contamination with foreign materials such as powder, dust, dirt,
etc.
- Any leftover powder should be kept in an appropriate area that is
cool and dry. Do not expose to the air too long as the powder
properties may deteriorate with the moisture
