S90

S90 Slow thinner for dyes/stains

Slow-evaporating thinner for Technocolor solvent-borne dyes and stains. Made for cutting stains on open-pored wood: the slow evaporation improves flow, gives even, gradual drying and reduces runs, bubbles and lap marks. Does not change the dye shade. Use at the ratio given for the material being thinned. Test first when using it with other brands' materials. Per the dealer, the thinned material can be applied by spray gun, brush or wiping.

CTU, CLT, CIT, CPS dyes/stains on open-pored wood — oak, ash, anegre, mahogany
Large panels or a hot shop where S10/S12 flash too fast and leave lap marks
Spray-and-wipe (CPS, CIT) — more time to wipe
UV schedule on anegre: CPS 100 / CFC3 200 / S90 200

Application

HVLP

Nozzle: 1–1.3
Pressure · fluid: gravity cup / low-pressure tank 0.5–1.0 bar
Pressure · air: 1.5–2 bar inlet; ≈0.7 bar at cap
Spray viscosity: < 12 (below the useful range of the DIN4 cup — practically solvent-thin) s DIN4
Consumption: 80–100
Coats: 1 even wet coat; second light pass only to correct colour
Flash-off: ≥5 at 20–25 °C (schedule); with S90 on open pores allow 10–15 before primer
Why ru: Морилка, разбавленная растворителем в 5–20 раз, жидкая как вода (~10–12 с DIN4) с почти нулевым сухим остатком; HVLP-сопло 1,0–1,3 мм при низком давлении на головке даёт тонкое распыление и малый отскок — стандартная практика для морилок на растворителе. Расход — с официальных страниц красителей; межслойная выдержка из UV-схемы (5 мин) увеличена, поскольку S90 — самый медленный разбавитель для красителей (каталог, с. 19).

S90 is never sprayed on its own — this is how a stain cut with S90 goes on. Small 1.0–1.3 mm tip, wide fan, one even wet pass. The slow evaporation lets colour soak into open pores and avoids lap marks on large panels; with CPS and CIT it leaves time to wipe back with a rag after spraying.

Airmix (air-assisted airless)

Nozzle: 0.18–0.23 mm (07–09 thou), fine-finish tip
Pressure · fluid: 5–10
Pressure · air: 1–2
Consumption: 80–100
Why ru: Официальная страница методов: airmix подаёт материал под давлением до 20 бар при распыляющем воздухе 1–2 бар; водоподобной морилке нужна лишь нижняя граница давления материала и малое финишное сопло. Медленный растворитель дольше держит слой мокрым, поэтому на вертикалях растёт риск потёков.

Production staining with S90-cut stains: keep fluid pressure at the bottom of the range — on verticals the slow thinner runs more easily.

Cloth or pad

Consumption: 80–100
Why ru: На официальных страницах CPS/CIT указано «распылить и протереть» при 80–100 г/м²; когда нужна протирка, обычно берут медленный разбавитель — он задерживает испарение.

Spray-and-wipe (CPS, CIT): S90 lengthens the window for wiping and packing colour into the pores — handy on oak, ash, anegre.

Roller

Consumption: 5–15 (CIT) / 10–20 (CPS)
Why ru: Расход при вальцевании — с официальных страниц CIT/CPS; медленный разбавитель, чтобы морилка дольше оставалась открытой на вальцовых машинах, — стандартная практика линий, Technocolor для S90 это отдельно не указывает.

Roller-coating CIT/CPS dyes on flat panels: S90 slows drying on the roller and on the belt.

Brush

The dealer lists brushing. The slow S90 gives time to even out the stain without lap marks; wipe off the excess with a rag.

Process and compatibility

Goes into: CTU, CLT, CIT, CPS
Alternatives · Faster: S10, S12
Alternatives · Other: LZC97 (CLT, CIT), water (CTU, CLT)
Choosing: Fine pores (beech, birch, maple) → S10; medium → S12; open pores (oak, ash, anegre), large panels, shop above ~25 °C → S90. S12 and S90 can be blended to tune the speed. The slower the thinner, the deeper and more even the colour goes into the pores, and the longer you wait before priming.recommended
Temperature and humidity: stain dried 5 min at 20–25 °C before UV fillerschedule
Don'ts: Don't use S90 to thin 2K PU/acrylic materials — those take S30/S31/S50/S70/S80, with S100 as the retarder.
Don't prime over wet stain: S90 dries slower than S10/S12 — allow at least 10–15 min at 20 °C or force-dry.
Don't flood S90-cut stain onto verticals — it will run.
S90 is not a hardener and does nothing for cure.

Storage

Packaging: 1 l,5 l,25 ldealer
Storage temperature: closed original container, cool, away from heat and flamerecommended

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