RAL 6029 Top quality customized professional colorful polyester
powder coating paint
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
