Properties of Powders
Architectural Polyester Pearlescent Powder Coatings
For maximum protection it is essential to pretreat architectural components prior to the application of Thermaset Limited Architectural Polyester Matt Pearlescent 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.
Thermaset Limited Architectural Polyester Matt Pearlescent Powder Coatings can be applied by manual or automatic electrostatic spray equipment, an even dry film thickness of 60 - 70 microns is recommended. Only one batch and one spray run should be used for components that will be visible simultaneously after assembly.
Generally good resistance to acids, alkalis and oil at normal temperatures.
