S12
S12 thinner for nitrocellulose (NC) materials and stains
Medium-evaporation thinner. The official page says it is for cutting dyes; the catalog and the dealer specify stains on medium-pored timber. It is also the only thinner listed for NTL20 SM nitro lacquer.
- Cutting CTU, CLT and CIT transparent dyes, 500–1000 % (CIT up to 2000 %)
- Cutting CPS solvent pigment stains, 500–1000 % (concentrates up to 2000 %)
- CTU 100 : CFS1 150–200 : S12 500 mix in the Technocolor schedules
- Thinning NTL20 SM nitro lacquer, 25–40 %

- Why ru
- Морилка, разбавленная растворителем в 5–10 раз, имеет вязкость воды (~10–12 с DIN4) и почти нулевой сухой остаток; сопло HVLP 1,0–1,3 мм при низком давлении на головке даёт тонкий ровный распыл и меньше тумана/отскока — стандарт для морилок-красителей на растворителе. Расход 80–100 г/м² и выдержка 5 мин — из официальных страниц и схем по красителям.
S12 is never sprayed on its own — this is how the stain cut with S12 (500–1000 %) goes on. The mix is basically solvent-thin: small 1.0–1.3 mm tip, wide fan, one even wet pass without puddling in the pores. Profiles can be wiped back with a rag after spraying. This setup is not for NTL20 SM nitro lacquer (120–150 g/m²), which needs a normal lacquer tip.

- Pressure · fluid

- Consumption

- Why ru
- Очень маловязким смесям в airmix нужны только мелкое сопло и низкое давление материала; более крупные сопла/давление заливают поверхность. Типичная настройка для морилок в деревообработке.
For production staining with S12-cut stains; keep fluid pressure at the bottom of the range or it runs on verticals.
Process and compatibility

- Alternatives · Faster
- S10
- Alternatives · Slower
- S90
- Alternatives · Other
- LZC97, water (CTU, CLT only)
- Choosing
- Fine pores (beech, birch, maple) → S10; medium pores (oak, walnut, cherry) → S12; open pores, big panels or hot shop → S90. The slower the thinner, the deeper and more even the dye soaks into the pores, but the longer the wait before priming.catalog
- Temperature and humidity
- stain dried 5 min before priming: 20–25 °C (raised-panel doors PU schedule) / 25–30 °C (mouldings UV schedule)schedule
- Don'ts
- Don't use S12 to thin 2K PU/acrylic materials — those take S13/S30/S31/S50/S70/S80.
- It is not a hardener and does nothing for cure.
- Don't prime over wet stain: at least 5 min at 20–30 °C, longer on open-pored wood.

Safety: Highly flammable liquid. Use in a ventilated spray booth with an organic-vapour (A2) respirator and nitrile gloves. Keep away from ignition sources; solvent rags go in a closed metal bin.
