S80

Nozzle

unchanged — set by the host product (≈1.3–1.5 mm for thin clear acrylic/PU lacquers, 1.7–2.0 mm for high-solids primers and gloss enamels)recommended

Pressure · air

per host product; e.g. ATL50 G: 2.0–2.2 bar inlet with trigger pulled, ≤0.7 bar at the caprecommended

Spray viscosity

thin the host product to ~18–22 s DIN4 / VZ-4 at 20 °C, staying inside the % its datasheet allowsrecommended

Flash-off

allow roughly 25–50 % longer between passes/coats than with S50recommended

On verticals lay lighter passes with S80 — slow solvent runs. The film stays open longer, so it picks up more dust in a dirty booth. In return: less dry spray and better flow-out on gloss.

Pressure · air

per host product, typically 2.5–3.5 bar at the gunrecommended

Nozzle and pressure follow the host product. S80 helps against dry overspray at high atomising pressure.

Nozzle

per host product, typically 09–11 thou (0.23–0.28 mm) tips for 2K lacquers, 11–13 thou (0.28–0.33 mm) for enamels/primersrecommended

Pressure · fluid

per host product, typically 40–80 bar fluid, 1–2 bar atomising airrecommended

Pressure · air

1–2 barrecommended

On a warm production line S80 extends flow-out.

Nozzle

per host product, typically 11–13 thou (0.28–0.33 mm)recommended

Pressure · fluid

per host product, typically 100–150 barrecommended

The official coffin schedule runs PTL500 + C200 70 % + S80 40 % through airless on a robot.
