Excellent
properties

  • Excellent mechanical properties
  • Superior heat stability
  • Chemical resistance
  • Tough decorative finish

Specially selected resins

to give the hard durable finish associated with epoxy coating but with superior heat stability and excellent durability.

Typical applications for epoxy polyester powder coatings are those where a tough decorative finish is desirable such as domestic appliances and office furniture. For use requiring ultimate heat stability and outside durability polyester powder should be used.

Substrate Preparation

For maximum adhesion the substrate must be thoroughly cleaned of grease, rust etc. by shot blasting, solvent or chemical degreasing. For maximum protection it is essential to pretreat the substrate prior to the application of Thermaset Limited epoxy-polyester powder coatings.

Aluminium

Aluminium components should receive a full multi-stage chromate conversion coating or similar chrome-free pretreatment to clean and prepare the substrate. Detailed advice should be sought from the pretreatment supplier.

Galvanized steel

Galvanized steel requires multi-stage pretreatment with either zinc phosphate or chromate conversion. Depending on the type of galvanizing, degassing or use of anti bubbling additives may be required. Detailed advice should be sought from the pretreatment supplier.

Ferrous substrates

Ferrous substrates require iron or zinc phosphate pretreatment. Detailed advice should be sought from the pretreatment supplier.

Application

Thermaset Limited epoxy-polyester powder coatings can be applied by manual or automatic electrostatic spray equipment, general recommendation is for a film thickness of 60 - 100 microns depending on covering power and colour, with a minimum recommendation of 60 microns.

Coating Properties

Test Panels, 50 microns thickness applied to light weight zinc phosphated steel.

Chemical Resistance

Generally excellent resistance to acids, alkalis and oil at normal temperatures.

Exterior Durability

Not suitable for constant exterior exposure.
