CFC3

CFC3 Stain binder for UV systems

Stain binder for UV finishing lines. It is added to CPS pigment stain together with the slow thinner S90 — presumably to lock the stain onto the wood so the UV filler and sealer that follow don't wash it out or pick it up (purpose inferred from the recipe; Technocolor does not describe it). In the official schedule for flat panels veneered in anegre (UV) it is used as CPS 100 % : CFC3 200 % : S90 200 %, the mixed stain at 60–80 g/m², 5 min flash at 20–25 °C, then the UV filler VTS20011. No product page on t-color.ru, not listed at t-colormarket.ru (code search returns nothing), no TDS found.

Mixing matrix

  • CPSAdditive
    % by weight: 50 %schedule% by volume: 50 %schedule

    Staining anegre veneer in the UV schedule: CPS pigment stain carries the colour.

    Ready mix is ~20 % CPS, 40 % CFC3, 40 % S90. Apply 60–80 g/m².

  • S90Thinner
    % by weight: 100 %schedule% by volume: 100 %schedule

    S90 is a low-evaporation thinner which the Technocolor catalog assigns to stains on open-pored timber (anegre is one). The official CPS page also lists S90 among its thinners (S10/S12/S90).

    This schedule names only S90; S10/S12 (allowed for CPS on its product page) are not offered here.

  • CFC3Additive
    % by weight: 200 %schedule% by volume: 200 %schedule

    As written in the schedule: 200 parts CFC3 and 200 parts S90 per 100 parts CPS.

    Same recipe as the two lines above, expressed on the stain as base.

Percentages are per 100 parts of component A.

Stir the CPS before measuring — the pigment settles. The schedule does not say whether % is by weight or volume; weighing is easier and more repeatable. Spray an even coat without runs — patches with excess binder will show under the UV sealer.

Don'ts
  • Don't put the UV filler on before the stain has flashed — trapped S90 under the UV layer means bubbles and poor adhesion.
  • Don't eyeball the ratio: too little binder and the next coat smears the stain, too much and you get haze and poor adhesion of the UV sealer.

Storage

Safety: No data. Treat as solvent-borne (the mix with S90 certainly is): spray booth with extraction, respirator with A-type filter, keep away from ignition sources.
