PTS52
PTS52 Thixotropic high-solids PU primer (sealer)
Two-pack polyurethane thixotropic primer/sealer with high solids (52 ± 1 % in part A). Dries fast, holds on verticals without sagging and sands easily. Built for spraying and electrostatic application on assembled pieces - chairs, cots, vertical surfaces in solid wood and MDF. Cured with PC20 or PC25 (50 % by weight), thinned with S50 or S70 (20-25 % by weight). Interior use.
- vertical surfaces
- children's cots
- chairs in various wood species
- assembled furniture
- solid wood and MDF, interior only
- tables (dealer tag)

Mixing matrix
- PC20Hardener% by weight: 50 %official% by volume: 55 %official
Default. 100 base + 50 PC20 by weight; mix on scales.
Official 50 % w/w / 55 % v/v. Dealer lists 50 / 50 (volume column looks copied from weight). Density check supports 55 % by volume. Mix by weight.
- PC25Hardener% by weight: 50 %official% by volume: 55 %official
When you want faster drying/hardness build (cold shop, quick turnaround to sanding) or slightly less yellowing.
Same ratio as PC20 (official 'PC20/PC25 50 %'). PC25 is the 'universal' aromatic hardener (dealer), the fastest/hardest end of the catalog chart; expect pot life a bit under 4 h.
- S50Thinner% by weight: 20–25 %official% by volume: 25–30 %official
Default thinner: medium evaporation, verticals, chairs, electrostatic work at 18-25 °C.
Dealer: 20-25 % by weight and by volume (volume likely copied). Catalog: S50 = medium evaporation, good cutting power, for PU and acrylic primers. Doesn't change cure time.
- S70Thinner% by weight: 20–25 %official% by volume: 25–30 %official
Slow: hot shop (above ~25 °C), large flat panels, force-drying - gives the primer time to level and avoids dry spray.
Catalog: S70 = slow evaporation, medium cutting power. More flow time, but more dust pick-up and sag risk on verticals. Doesn't change cure time.

Thixotropic primer levels poorly on flats: lay table tops a bit wetter and go to 25 % thinner (S70 when hot) if you get orange peel. Keep 20 % on verticals and chairs.

Methods page: electrostatic is the most economical method and is used mostly on chairs, table legs and cots - exactly PTS52's market. Ground the workpiece; wood below ~8-10 % MC conducts poorly - use a conductive primer if needed.
Process and compatibility
- Substrate preparation
- P150-P180 (schedule for beech chairs: K60, K80 pads), dust off, MC 8-10 %recommended
- Sanding
- P240-P320 after 3-4 h at 20 °Crecommended
- Temperature and humidity
- 18-25 °C, RH 50-70 %recommended
- Don'ts
- Don't eyeball by volume - official and dealer volume figures disagree; mix on scales.
- Don't thin past 25 %: you lose the thixotropy and it will sag on verticals.
- Don't use the mix beyond 4 h at 20 °C - less with PC25 or in the heat.
- Don't leave the hardener can open - PC20/PC25 react with moisture.
- Don't lay more than ~150 g/m² per pass: pinholes in the pores and shrink-back.
- Don't sand while the paper still gums up.
- Not for exterior use.
Storage
- Shelf life
- ~12 months (typical, unconfirmed)recommended
- Storage temperature
- 5–25 °Crecommended
Safety: Flammable. Hardener contains isocyanates - spray only in a ventilated booth with an A2P2 respirator (or supplied air), gloves and goggles. Keep away from ignition sources.
