ThermaPrime PBP 110 technical data
Epoxy Powder Coating Barrier Primer
Thermasets’ Thermaprime PBP 110 TLE-C540-M is Grey RAL 7035 but a similar powder coating can be matched to customer supplied samples or to many of the RAL and BS colour ranges.
Approx 3%
Approx 1.8
Suitable for electrostatic spray
- 10 minutes @ 180°C peak metal temperature
For maximum adhesion the substrate must be thoroughly cleaned of grease, rust etc. by shot blasting, solvent or chemical degreasing. For maximum protection it is essential to pretreat the substrate prior to the application of Thermaset Limited Thermaprime PBP 110 Epoxy Powder Coating Barrier Primer.
Recommended substrate preparation is by solvent or chemical degreasing followed by grit blasting to minimum SA 2.5, Rz 35-65μm, Ra 6-10 μm and/or degreasing and zinc phosphating.
If using chemical pretreatments, follow advice from the pretreatment chemical supplier.
Thermaset Limited Thermaprime PBP 110 Epoxy Powder Coating Barrier Primer TLE-C540-M can be applied by manual or automatic electrostatic spray equipment, an even dry film thickness of 60 - 100 microns is recommended.
Not suitable for exterior exposure. For exterior applications Thermaprime PBP 110 Epoxy Powder Coating Barrier Primer TLE-C540-M should be over-coated within 2-3 weeks with a suitable exterior grade coating such as an architectural grade polyester powder coating or polyurethane wet paint top coat.
Generally good resistance to acids, alkalis and oil at normal temperatures.
Thermaset Limited Thermaprime PBP 110 Epoxy Powder Coating Barrier Primer TLE-C540-M is suitable for use on items covered by Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2012 (Directive 11/65/EU, ROHS 2). Product contains none (or less than the maximum allowed amount) of the following restricted chemicals: Lead, Mercury, Cadmium, Hexavalent Chromium or their compounds, Poly-brominated biphenyl (PBB) or Poly-brominated diphenyl ether (PDBE) flame retardants, Bis(2-ethylhexyl) phthalate (DEHP), Benzyl butyl phthalate (BBP), Dibutyl phthalate (DBP), Diisobutyl phthalate (DIBP).

ThermaPrime PPC 120
Anticorrosive Powder Coating Primer
Zinc-free epoxy-polyester powder coating primer designed for improved corrosion protection of mild steel. It contains advanced anticorrosive pigments which have a passivating effect on the steel substrate. If penetrating damage is done to the coating, the Thermaprime PPC 120 system will considerably limit the spread of corrosion.

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.

Approximately 5%
1.5 g/cm3
Suitable for electrostatic spray
- Partial cure 5 minutes @ 180°C metal temperature
- Full cure 10 minutes @ 180°C metal temperature or longer to suit topcoat
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.
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.
