Properties of Powders

Post Forming Powder Coatings
Application

Thermaset Limited Post-forming Powder Coatings can be applied by manual or automatic electrostatic spray equipment. Even dry film thickness is recommended.

  • Polyester Coatings: 60 - 70 microns is suggested
  • Epoxy Polyester Coatings: 60 microns is suggested
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 Post-forming 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.

Exterior Durability

Polyester Coatings:
After 12 months exposure, minimal loss of gloss or colour change. No film breakdown or loss of protection.

Epoxy Polyester Coatings:
Not designed for long term exterior exposure. Some chalking and loss of gloss can be expected after 3-6 months continuous outdoor exposure.

Chemical Resistance

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