Various Substrates for Powder Coating

Substrates

Aluminium,steel,zinc alloys,copper and galvanized steel are common metals on which powder coatings are applied.  In a number of cases where normal service conditions apply, satisfactory properties can be obtained on thoroughly cleaned metal.

Aluminium

For aluminium and its alloys,performance can be upgraded using a proprietary chromate conversion coating, even though the clean surfaces are easily coated and adhesion is excellent

Steel

For iron/steel surfaces maximum corrosion and salt spray resistance are given by a zinc phosphate conversion coating.

Zinc alloys

With all zinc based substrates such as Zintec, Mazac and Galvanised Steel a suitable phosphate coating is recommended.
