Nasmyth assures product resistance to the elements through our passivation service. Conforming to industry standards, we present a wide choice of specific methods for optimum protection from corrosion; working with differences in acid types, temperatures and additives to promote oxidisation.

Suited for casted and alloyed aluminium, SurTec 650 is a hexavalent chromium free passivation for aluminium suitable for alloyed and casted aluminium. It is a versatile pre-treatment Nasmyth use prior to adhesive applications and laquer services we provide. The layer created is a result of easy immersion giving first-rate corrosion protection.
