What it is and why choose it

Epifanes PU Speedcoat is a professional, two-component acrylic polyurethane topcoat designed for high-quality spray applications on GRP, steel, aluminium and plywood. It delivers an extreme high gloss finish with excellent flow, fast overcoating times and long-term gloss retention. Once fully cured, the coating is scratch and weather resistant and can be polished for an even deeper, high-end appearance.

Main features

• Two-component, chemically drying acrylic polyol system.
• Extreme high gloss finish with outstanding flow and levelling.
• Dedicated to spray application with very short overcoating times.
• Durable surface: scratch resistant and weather resistant.
• Suitable for interior and exterior use with the correct priming system.
• Polishable after full cure for enhanced depth and gloss.
• Available in Epifanes colours, maritime-related colours and RAL colours (on request).

Drying and recoat times (at 35 µm dry film thickness, 65% R.H.)

• 15°C:
  • Dust dry: 1.5 hours.
  • Recoatable: 2 hours.
  • Sandable: 30 hours.
  • Pot life after mixing: 4 hours.
• 20°C:
  • Dust dry: 1 hour.
  • Recoatable: 1 hour.
  • Sandable: 24 hours.
  • Pot life after mixing: 3 hours.
• 25°C:

  • Pot life after mixing: 1.5 hours.

The indicated times depend on film thickness, ventilation and object geometry. Higher wet film thicknesses, limited ventilation and horizontal parts can extend drying times. Polishing is possible after 1 week at 20°C (7 days according to application guidelines).

Substrate and application conditions

• Suitable substrates: Well cured, cleaned, degreased and sanded intact two-component paint systems. For new systems, build up with Epifanes Epoxy Primers and Epifanes Poly-urethane Primer.
• Field of use: Spray application only on GRP, steel, aluminium and plywood for interior and exterior use in combination with the correct priming system.
• Application methods: Conventional air spray, HVLP and RP spray guns. Airless spray is not advised. Best results are achieved with an RP gun.
• Application temperature: Minimum 15°C, maximum 30°C.
• Relative humidity: Minimum 50%, maximum 75%.
• Application notes:
  • Apply evenly and avoid excessive wet film build to prevent curtains and drying problems.
  • Avoid large temperature differences between product, substrate and working area.
  • Wet-on-wet application is possible once solvents have evaporated (recoat with itself after 60–90 minutes at 20°C).
  • If a subsequent coat is applied after 48 hours (20°C), sanding is required.
  • When polishing or when extra gloss and depth are desired, one or more coats of Epifanes PU Speedcoat Clear Gloss can be applied over Epifanes PU Speedcoat Colour.

Spray parameters

• Air / HVLP spray:
  • Thinning: 15–20%.
  • Nozzle: 1.2–1.6 mm.
  • Pressure: 2.5–3.5 bar.
  • Viscosity: 17–20 seconds DIN-cup 4 mm.
• RP spray:
  • Thinning: 15–20%.
  • Nozzle: 1.1–1.3 mm.
  • Pressure: 2.2–2.5 bar.
  • Viscosity: 17–20 seconds DIN-cup 4 mm.
• Application remarks:
  • Airless spray is not advised.
  • With pressure-feed paint containers, pot life may be shortened due to temperature increase in the container.
  • Check filter housing and filters for contamination before spraying.

Applications and use cases

• High-gloss finishing coat on properly primed GRP, steel, aluminium and plywood structures.
• Interior and exterior spray finishing where fast overcoating and long-lasting gloss are required.
• Systems built over Epifanes Epoxy Primers and Epifanes Poly-urethane Primer on new constructions.
• Projects where polishing after curing is planned to obtain a mirror-like finish.

FAQ

1. Can Epifanes PU Speedcoat be applied by brush or roller?

No. This product is solely designed for spray application and is not suited for brush or roller application.

2. On which substrates can I use this product?

It is suitable for use on GRP, steel, aluminium and plywood, always in combination with the correct priming system and on well-cured, degreased and sanded two-component paint systems.

3. How many coats are recommended?

A minimum of three coats is recommended, achieving a total dry film thickness of approximately 90–120 µm.

4. When can I recoat wet-on-wet?

Epifanes PU Speedcoat Colour can be recoated with itself wet-on-wet after approximately 60–90 minutes at 20°C, once the solvents have evaporated.
