PPS01
PPS01 Fire-retardant white PU primer
Two-pack white polyurethane primer with fire-retardant additives for timber structures indoors. Fast drying, high solids (71 %), sands easily. When heated, the fire-retardant components break down and release a non-combustible gas that starves the fire of oxygen and slows flame spread. As the PPS01 primer + PPL01 enamel system it rates Group I fire-retardant efficiency to GOST R 53292-2009 (cl. 6.1). No official t-color.ru page - data from t-colormarket.ru and the Technocolor catalogues.
- fire protection / improved fire resistance of interior timber structures
- primer under the white fire-retardant enamel PPL01 (pigmented system, Group I)
- public interiors needing certified fire protection: wall panelling, doors, cladding, stairs

PC60 is non-yellowing; under white enamel that doesn't matter for a primer. The fire certification was most likely run on PC20 - confirm with Technocolor before swapping.

Spray, 150 g/m². 1.8-2.0 mm tip; a 1.5 mm won't atomise it well - if that's all you have, thin to 30 % S50 and accept less build per pass. 15-20 cm, 50 % overlap. Stir the base thoroughly before mixing.
Conventional spray

Technocolor just says 'spray'. Transfer only up to 40 % (methods page) - mix more than you think.

Not listed by Technocolor. High transfer, easy to hit 150 g/m² in one pass; watch for sags on verticals.
Brush
- Why ru
- Дилер и оба каталога указывают только распыление.
Not recommended: Technocolor specifies spray only; a brush won't lay an even 150 g/m², which the fire rating depends on. Touch-up only.
Process and compatibility
- Substrate preparation
- Wood/MDF at 8-12 % MC, sanded P150-P180 (solid) or P180-P220 (MDF), de-dusted. No oil, wax or old finish - the fire rating assumes application to bare wood.recommended
- Goes over
- bare wood (interior timber structures) / bare MDF / wood boards
- Goes under
- PPL01
- Sanding
- 280–320 grit Precommended
- Don'ts
- don't eyeball the hardener - 50 % by weight
- don't use the mix past 3-4 h
- don't sand before full dry (8 h)
- don't skimp - below 150 g/m² per layer the fire rating isn't guaranteed
- don't topcoat with ordinary (non-fire-retardant) enamels if you need the certified system
- not for exterior use - interiors only
Storage
