PPS10
PPS10 White PU primer (economy)
Two-pack white polyurethane primer, economy grade. High solids and good fill at a low price, good adhesion and hiding, resists runs and sags, dries fast, has good hardness, and shows minimal shrink-back over time. Made for high-throughput matt finishing lines - MDF doors and panels under coloured enamels.
- priming MDF furniture doors and panels for coloured PU enamels
- high-throughput matt finishing lines (doors, cabinet fronts, routed parts)
- budget primer where cost matters more than top-end performance

Answers are based on the PPS10 data and the products it mixes with.
Mixing matrix
- PC20Hardener% by weight: 30 %official% by volume: 50 %official
Default option - the only one the dealer lists; in the 2025 catalog.
Fixed ratio - weigh the hardener. PC20 and PC10 are both fast/hard aromatic hardeners (2025 catalog chart); PC20 sits slightly better on the yellowing scale. Pot life 2 h (dealer).
- PC10Hardener% by weight: 40 %official% by volume: 70 %official
Alternative to PC20; in the 2022 catalog it was PPS10's only hardener.
Fixed ratio. Pot life and drying with PC10 are not published - assume about 2 h and don't push it.
- S50Thinner% by weight: 10-20 %official% by volume: 20–40 %official
Always. 10 % for maximum build on a big tip (2.0 mm); 20 % on 1.8 mm, routed profiles and relief.
S50 is the universal normal-evaporation thinner. Don't go past 20 % - the primer loses build and starts to run.
- S80Thinner% by weight: 10–20 (typ. 15) %recommended
Only in the heat (above ~25 °C) or on big flat panels when the primer goes on dry.
Not listed by Technocolor for PPS10. More dust pick-up and more sag risk.

- Gun distance

Officially just 'spray 150 g/m²', gun type not stated. Big tip, fan fully open, 50 % overlap. Don't exceed the recommended film (dealer note).
Conventional spray

Conventional air spray - transfer efficiency up to 40 % (methods page).

Not listed by Technocolor, but it's the normal tool for the 'high-throughput lines' PPS10 is aimed at. 2 h pot life - flush the pump in time.
Airless
- Nozzle
- 0.33–0.38 mmrecommended
- Pressure · fluid
- 120–180 barrecommended
Not listed by Technocolor. High transfer, coarser atomisation - more sanding afterwards.
Process and compatibility
- Substrate preparation
- MDF: sand P180-P220, edges and routed profiles P240, de-dust. Solid wood: P150-P180. Wood moisture 8-12 %.recommended
- Goes over
- bare MDF / bare solid wood
- Goes under
- coloured PU enamels (PPL series, RAL/NCS)
- Sanding
- 280–320 grit Precommended
- Don'ts
- don't eyeball the hardener - 30 % PC20 or 40 % PC10 by weight
- don't mix PC10 and PC20 in one batch - different ratios
- don't use the mix after 2 h
- don't thin past 20 % S50
- don't lay more than 150 g/m² per coat
- don't sand while it still gums the paper
- don't leave it as a finish - it goes under enamel
