For maximum protection it is essential to pretreat components for exterior use prior to the application of MT-800. Aluminium components should receive a full multi-stage chromate conversion coating to clean and condition the substrate. Detailed advice should be sought from the pretreatment supplier. Galvanised steel also requires multi-stage pretreatment using either zinc phosphate or chromate conversion. Degassing of galvanised steel prior to powder application is considered mandatory – follow the procedural advice of the pretreatment supplier. MT-800 products may also be used on other substrates (eg. mild steel fabrications) for internal applications; nevertheless zinc phosphate pretreatment is regarded as essential.
Los polvos MT-800 AM se pueden aplicar mediante equipos de pulverización electrostática manuales o automáticos. El polvo no utilizado se puede recuperar con el equipo adecuado y reciclar a través del sistema de recubrimiento.
