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.
Os pós MT-800 AM podem ser aplicados por equipamentos de pulverização eletrostática manual ou automática. O pó não utilizado pode ser recuperado com o equipamento adequado e reciclado no sistema de revestimento.
