Powder Coating Primers
Powder coatings are extremely durable, exceptionally resistant to corrosion, and able to withstand exposure to harsh UV rays. Even so, in some circumstances a dual layer is required to achieve optimal corrosion resistance and meet specific appearance requirements. In these cases, you can use a primer base coat for corrosion resistance and a topcoat to improve the aesthetic appearance.
We offer the following primer options for any circumstance in which a layering system is preferred.
End user testing is required when applying topcoats, either liquid or powder, to cured primer films. Intercoat adhesion can be influenced by degree of cure, overcuring, and curing method. If you have any questions, please contact us here or call 800-533-9067

7520-70138 TruZinc™ Zinc Rich Primer
TruZinc™ Primer is manufactured using a unique process that allows a significantly greater amount of zinc during the extrusion process. The increase in the zinc content dramatically increases protection of the substrate against corrosion. This primer can be used a as single coat system or as a primer in a multi-coat system. As a coating based on epoxy technology, TruZinc™ Primer does not have good gloss retention when exposed to sunlight. If appearance stability is required on coated materials an exterior durable topcoat is required.

Benefits:
- Increased protection of substrate against corrosion
- Can be used as a single coat system or as a primer in a multi-coat system

7820-71737 MIL Spec Primer 53022
The MIL Spec Primer 53022 is a gloss epoxy primer formulated to meet the Federal Standards of MIL-PRF-53022, MIL-32348 CARC powder primer, Type 1, Class 1, Grey 26622, and is on the Qualified Products Database. MIL Spec Primer Grey’s high adhesion strength and low permeability make it an excellent performer as a barrier primer in a primer-topcoat system. However, the unique qualities of a higher level of chemical resistance and a good balance of physical and corrosion resistance properties allow it to be used as a single coat interior system. Testing is recommended with each application to determine the variables that influence the coating system’s performance. Such variables include substrate and pretreatment characteristics, primer and topcoat film thickness, and end use environments.

Benefits:
- Good balance of physical and corrosion resistance properties
- Can be used as a one-coat interior system
- Excellent adhesion and low permeability
