PTS20701
PTS20701 high-molecular (high-solids) clear PU primer / isolating sealer
Two-pack clear polyurethane primer with high solids (57 % in part A), cured with the slow, flexible aromatic hardener PC72. Dries fast and sands well (official site), resists shrink-back (woodonline). For interior finishing of articles in various wood species (t-colormarket, woodonline). Technocolor's special-effects catalog uses it as the first coat — the 'isolator' — under the white PU primer PPS20 in the Craquelure and Soft-touch systems. A sibling of PTS20700 (same 57 % solids, same — typo-ridden — viscosity format, same 3–4 h pot life) but catalysed with PC72 at 30 % instead of PC20 at 50 %.
- clear build/sanding primer on solid wood and veneer, interior
- isolating first coat under white PU primer PPS20 (Craquelure, Soft-touch systems)
- fronts, doors, kitchens, bathrooms (woodonline 'finishing system' tags)

Mixing matrix
- PC72Hardener% by weight: 30 %official% by volume: 35 %official
always; the only hardener listed
Fixed ratio — weigh it (30 %) or measure by volume (35 %). Don't substitute PC20 — that's the PTS20700 recipe; PC72 is slower, more flexible and yellows more.
- S50Thinner% by weight: 20–30 (typ. 25) %official% by volume: 25–40 (typ. 32) %official
always, to working viscosity
S50 is the universal, normal-evaporation thinner. 20 % for maximum build (big tip), 30 % for 1.7 mm HVLP and profiles. Thinner doesn't change cure time.
- S80Thinner% by weight: 20–30 %recommended
heat above ~25 °C, large flat panels — replace part of the S50 (workshop advice)
More dust pick-up and sag risk on verticals; not a Technocolor recommendation.

- Temperature and humidity
- материал, деталь и воздух 18–25 °C, RH 50–70 %recommended
- Don'ts
- Don't mix it up with PTS20700: that one takes PC20 at 50 %, PTS20701 takes PC72 at 30 % (35 % by volume).
- Don't use mix older than 3–4 h.
- Don't sand before 4 h — PC72 is slow and the primer will clog the paper.
- Don't lay more than 150 g/m² per coat (max two coats wet-on-wet) — sink-back and solvent pops.
- Don't leave it as a topcoat or use it under a pale clear finish without a non-yellowing lacquer on top — PC72 yellows the most.
- Don't spray above 75–80 % RH.

Safety: Highly flammable (solvents in the base and in S50). PC72 is an aromatic isocyanate: spray in an extracted booth, wear an A2P2 respirator (air-fed is better), nitrile gloves and eye protection. No sparks; solvent rags in a closed metal bin. (General 2K PU rules — no manufacturer SDS found.)
