EPOXY POWDER COATINGS

Gives hard durable protective finishes with excellent adhesion and chemical resistance. Epoxy Powder Coating has good electrostatic charging properties and excellent transfer efficiency.

Recommended uses include general industrial components and applications requiring a good all round coating, such as household goods. When long term exterior durability or heat stability is essential a powder from our range of epoxy-polyesters and polyesters should be selected.

Post Forming Powders

Speciality Powders

Application

  • Suitable for application by proprietary manual or automatic corona discharge equipment and triboelectric charging guns.

Pretreatment

  • It is essential to ensure that the surface to be coated is free from dust, rust, scale, oil, etc. Chemical pre-treatment of the substrate is essential to increase the long term corrosion resistance. Further information is given in our publication ‘Application of Powder Coatings’.

Solvent & Chemical Resistance

  • Good resistance to acids, alkalis and solvents at room temperature. May be attacked by ketones. Refer to information sheet ‘Chemical Resistance of Powder’.

Exterior Durability

  • Progressive chalking will occur but protective qualities are unimpaired providing adequate pretreatment and thickness are applied.

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. Further information is given in our Health and Safety Sheet.
