S101

S101 Retarder (PU thinner, very slow)

Retarder for 2K polyurethane (and acrylic) lacquers and enamels. The dealer names it alongside S100 as an either/or choice: in hot weather add 5–10 % (10–15 % in the ATL200 acrylic) on top of the main thinner to improve flow-out and avoid bubbles and dry spray. No S101 data of its own is published anywhere; everything below not tagged 'dealer' is derived by analogy with S100.

  • Hot-weather retarder for PTL200, PTL202 high-gloss PU lacquers
  • Hot-weather retarder for PPL500 white high-gloss PU enamel
  • Hot-weather retarder for ATL200 acrylic high-gloss lacquer
  • Against bubbles / orange peel on big panels above 25 °C

  • S70 / S80Thinner
    % by weight: 5–10 %dealer

    Hot weather, for better flow-out

    Main thinner (dealer): PTL200 — S80/S70 30–40 % (weight and volume); PPL500 — S80/S70 30–40 %. Official PPL500 page: S70 20–30 % by weight / 30–40 % by volume (hardener AC200 70 % / 90 %). S101 goes on top. S100 can be used instead.

    If S101 isn't available (S100 is the current catalog code)

    (derived) Don't stack S100 and S101 beyond 5–10 % combined (10–15 % for ATL200).

Add after hardener and main thinner, stir, check viscosity in a DIN4/VZ-4 cup. Gun set-up as for the host material. Thinner coats on verticals or it'll sag; keep the booth clean — the film catches dust for longer.

Conventional spray

Nozzle
по паспорту основного материала (1.4–1.6 мм лаки, 1.8–2.0 мм эмаль)recommended

High-pressure guns dry the fan out most in heat — this is where the retarder earns its keep.

Airmix (air-assisted airless)

Nozzle
по паспорту основного материала (лаки 0.009–0.011" / 0.23–0.28 мм; эмаль 0.011–0.013" / 0.28–0.33 мм)recommended

Airmix needs less thinner overall — keep the retarder at the low end (5 %).

Process and compatibility

Goes into
PTL200, PTL202, PPL500, ATL200
Goes with
S70, S80, S100, AC200, PC210, PC72
Temperature and humidity
Use in hot weather (rule of thumb: above ~25 °C). Normally not needed at 18–25 °C.recommended
Don'ts
  • Don't use as the only thinner
  • Don't exceed 10 % (15 % for ATL200) on top of the main thinner
  • Don't recoat early — solvent pop
  • Don't use in a cold shop — drags drying and causes sags

Storage

Packaging
n/a — no listing found
Storage temperature
в плотно закрытой таре, вдали от огня, 5–25 °Crecommended

Safety: Flammable organic solvent blend. Ventilation, A2 organic-vapour respirator, gloves; keep away from sparks and flames. In 2K mixes the hardener adds isocyanate exposure.
