Electrostatic thermoset polyester powder coating ,RAL 1001 beige color powder coat
Powder coating may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware and automobile and bicycle parts.
Pretreatment:
It is essential to ensure that the surface to be coated is free from dust or rust or scale and also oil, etc. Chemical pre-treatment of the substrate is essential to increase the long term corrosion resistance.
Application:
Suitable for application by proprietary manual or automatic discharge equipment and triboelectric charging guns.
Solvent & Chemical Resistance:
Good resistance to acids, alkalis and solvents at room temperature. May be attacked by dilute nitric acid, ketones and trichloroethylene. Refer to information sheet ‘Chemical Resistance of Powder’.
Exterior Durability:
Some chalking will occur after six months but protective qualities are unimpaired providing adequate pre-treatment is used.
Health & Safety:
Use in accordance with the Code of Safe Practice published by the Paintmakers Association of Great Britain, “Application of Powder Coatings Electrostatic Spraying”. Copies are available on request. To prevent inhalation of airborne powder, face masks capable of removing respirable dust should be worn. Skin contact should be avoided and any deposited powder removed with soapy water. Some powders, mainly bright red and yellow shades, contain lead chrome and cadmium pigments.

Powder Coating Processes:
Powder coating processes vary by the type of material being applied; however, they can generally be divided into four functions:
- Preparation of the surface
- Application of the powder
- Heating of the part
- Curing of the coating
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
