Dulux  Powder Coatings offer a range of stock powder coating primers for the purpose of improving product finishing for aesthetic and / or functional purposes. Dulux  can also design a primer for a particular end application where desired.
The range of stock primers include:
SU Primer (Sealer Undercoat) – is designed for very porous substrates such as galvanised metals or sand castings. This primer is used commonly on galvanised fences and fittings before a top coat is applied, to provide optimal film appearance and improved moisture resistance from sea spray.
UC Primer (UnderCoat) – is designed for general metal castings that need some assistance with pin hole resistance, as in the case of alloy wheel castings or balustrade fittings.
The UC primer also assists with preparing perforated or sharp edge metals that need additional film build to reduce risk of under creep corrosion. The advantage of the UC primer is the wider choice of top coats which can be applied, including various wet paints.
Zincshield® Primer – Zincshield is designed to provide additional corrosion inhibition on abrasively blasted steel products. The Zinc component provides sacrificial opportunities to the steel whilst the epoxy resin system provides improved chemical resistance and coating adhesion.
For more information refer to Zincshield.®  Brochure.

Zincshield® is a high zinc containing primer specifically formulated and designed for powder coating applications.

Zincshield® may be used with confidence on steel substrates as it protects steel from corrosion whilst providing a sound substrate for powder coating.

Zincshield® is excellent for use where corrosion inhibition is required.

Zincshield® is partially cured on the metal surface and then the desired top coat finish is applied. This two coat system is then co-baked to a full cure to ensure maximum polymer interaction and excellent intercoat adhesion.

Alternatively, Zincshield® can be fully cured to act as a single functional coating where UV stability is not a requirement.
