Powder coating primers and multi-layer systems

A primer is one part of the coating system, not a stand-alone performance guarantee. The substrate, pretreatment, primer, topcoat and cure of each layer must work together.

Define the complete system

Multi-layer specifications are used when the project calls for a defined base coat and topcoat rather than a single powder layer. The correct route depends on the metal, its condition, the preparation process, the exposure and the selected topcoat.

Substrate type, fabrication and surface condition.
Pretreatment process and quality controls.
Primer and topcoat compatibility.
Application sequence, target film build and coverage.
Curing conditions for each layer and the complete system.
End use, exposure and the test or specification to be met.
