ThermaPrime PZP 130

Zinc Phosphate Powder Coating Primer

Epoxy powder coating primer containing zinc phosphate. It is designed for improved corrosion protection of mild steel. Recommended for use as an anti-corrosive primer where good quality chemical conversion pre-treatment is recommended or specified but may not be available. It is intended to be over-coated with a suitable product from our range of coatings, depending on the end-use application.

We recommend that the primer should be partially cured prior to application of the topcoat. When the topcoat is cured for a minimum of ten minutes at 180 degrees C metal temperature (longer if specified for the topcoat) the primer will also fully cure.

The substrate must be in a clean, rust-free condition prior to application of the primer. Film thickness of the primer coat should be controlled to assist application of the second coat: trials are recommended to optimise application conditions.

Substrate Preparation

Thermaset Ltd's Thermaprime PZP 130 adheres to most metals and does not require other primers. Articles to be coated must be free from rust, grease, oil and mill scale. Solvent vapour degreasing is usually adequate.

Grit blasting to minimum SA 2.5, Rz 35-65μm, Ra 6 10 μm and phosphate or chromate conversion coatings may be used if even greater corrosion protection is specified. If using chemical pretreatments, follow advice from the pretreatment chemical supplier.

Care should be taken not to contaminate primer surface before over-coating. Should oil contamination by handling without gloves or over-curing of primer have occurred, the primer may need degreasing with a mild detergent and/or slight abrasion with 800 sandpaper. Remove dust by blowing with clean dry air.

Application

Thermaprime PZP 130 should be applied by corona electrostatic spray equipment, with an even dry film thickness of 55 - 65 μm. Tests should be carried out to ensure suitability prior to full-scale application. Please note we strongly advise against the use of pre-treatment over the zinc primer between coats. Subsequent topcoats may require modified application conditions, e.g. lower voltage.

ThermaPrime EEP 140 Extreme Edge

Anticorrosive Primer Powder Coating

This product has been developed to provide a solution to issues where there are extreme levels of premature corrosion at the point of sharp edges on fabrications. Where standard powders naturally flow away from these edges, this innovate product not only maintains all of its anticorrosive properties but it also has the ability to restrict the negative flow away of powder from these edges, allowing the primer to retain its integrity at this problematic area on fabrications. In using EEP 140 it will present a sound base preparation for the topcoat to further enhance coating protection on these edges.
