Additional Information

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 Architectural Polyester Powder Coating.


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.

Storage & Shelf Life

24 months when stored in cool (below 25° C) dry conditions. Open boxes must be resealed.
