Why Prime?

A primer is applied to ensure a good adhesion between the surface of the parts and the powder coating. The primer is diluted to the desired strength before being evenly applied using a hand spray system, the primer is a dry in place substance and is not removed from the parts.

Zinc Shield

It is a high Zinc containing primer specifically designed for Powder Coating applications. Zincshield may be used with confidence for improved corrosion resistance and durability and can also be used as a functional topcoat where appropriate. PT Powdercoaters and Sandblasting Services recommend the use of this over any sandblasted substrate.


Provides a barrier coating for improved corrosion resistance and is ideally suited to non-ferrous metals such as aluminium, zinc castings, hot dipped galvanized and other zinc coated substrates.

  • Very good adhesion
  • Very good corrosion protection
  • Very good surface hardness
  • No solvents or emissions
  • Good chemical resistance
  • Hard wearing/serviceable finish
