PPL50 SM
PPL50 SM White thixotropic PU enamel, semi-matt (30 gloss)
Two-pack white polyurethane semi-matt enamel (30 gloss), thixotropic. Excellent hiding, resists runs and sags, good physical and chemical resistance. Made as a topcoat for vertical spraying and for carved, complex-shaped parts.
- Topcoat on vertical surfaces (fronts, doors, panels)
- Carvings and complex-shaped parts
- Furniture fronts and panels in wood and MDF
- Interior use only

Mixing matrix
- PC60Hardener% by weight: 50 %official% by volume: 60 %official
the only listed hardener — always
Fixed ratio, 50 % by weight (2:1) — weigh it. PC60 is aliphatic, yellowing-resistant group, 29 ± 1 % solids.
- S50Thinner% by weight: 20–30 (typ. 25) %official% by volume: 30–35 %official
default — normal evaporation, vertical work
S50: medium evaporation, good solvency; catalog lists it for PU primers, matt lacquers and enamels. Thinner does not change cure time.
- % by weight: 20–30 %catalog
S70 (slow) — catalog alternative. Use it in heat above ~25 °C and on large panels — our recommendation; the catalog gives no conditions.
Official page and dealers list S50 only; S70 appears only in the catalog (S70: slow evaporation, for deep-matt and high-gloss PU/acrylic materials). No % by volume published for S70. Slow thinner lengthens dust time and sag risk; the thixotropy offsets part of that.
- S100Thinner% by weight: 5–10 %recommended
only in heat when the enamel goes on dry

Fan fully open, 50–75 % overlap, 10–13 CFM compressor. On verticals one full wet pass — the thixotropy holds it; don't exceed 150 g/m² per pass. Never sand or polish the final 30-gloss coat — the sheen goes patchy.

Conventional air spray is the universal, most common method (Technocolor methods page), transfer efficiency up to 40 %.

The catalog shows only the orange (spray) icon for PPL50; the turquoise (airmix/airless) icon appears e.g. on PPS50. Technocolor's methods page says airmix suits topcoats better than airless — acceptable as a production method.
Airless
- Nozzle
- 0.28–0.33 mm (= 11–13 thou)recommended
- Pressure · fluid
- 100–150 barrecommended
Not recommended for the topcoat: coarser atomisation, uneven sheen, overbuild.
Process and compatibility
- Substrate preparation
- White PU primer (PPS20/PPS50/PPS50277) sanded P280–P320 (P320–P400 on MDF), de-dusted, free of silicone, oil and wax. Resinous wood and MDF: PTS71 isolator first.recommended
- Sanding
- P320–P400 between coats; never sand or polish the final coat.recommended
- Temperature and humidity
- 18–25 °C, RH 50–70 %. Above 25 °C use S70 instead of S50.recommended
- Don'ts
- No hardener other than PC60
- Weigh the hardener, don't eyeball it
- Don't exceed 150 g/m² per pass
- Don't sand or polish the final 30-gloss coat
- Interior only
- Don't spray mix older than its 4 h pot life
- Stir the base thoroughly before use (dealer)
