What ink system and conditions are used in the application tests?21 Aug 03:41
The application tests (from FOIL's own application-test report, record exp-9076-000S9076 / S 9076 Batch No 64) use:

Ink system
  • Ink base: "Nitrocellulose Polyurethane" (role verbatim: ink base)
  • Colourant systems: "Violet 23" and "Violet 27" (role verbatim: colourant system); the record's samples list also contains a "Carbon Black N 330" system
  • Reference standard: "BYK 9076 / Finalux 108", listed as "reference standard for both ink systems" — this is the vendor/reference standard, not FOIL's measured data
  • Aim, verbatim: "Application test of S 9076 Batch No 64 vs BYK 9076 in ink systems (Violet 23, Violet 27) in Nitrocellulose Polyurethane ink base"

Conditions (verbatim, identical for both colourant systems)
  • Re-solubility tested in "Ethyl Acetate + Toluene (50:50)"
  • Viscosity: "B4 Cup @26°C"
  • Gloss: "@ 60°"
  • Also measured per system: Grinding (µm), Colour Shade, Transparency, Color Strength (%), Adhesion (Tape Test), Separation, Settling

Caveats
  • This record is marked STUB — it is an unlinked sample, not a confirmed experiment.
  • The two merged fragments contain conflicting measured values (e.g. Violet 23 Colour Strength "98-99" and Gloss 55.6 in one narrative vs "96-97" and 63.6 in the structured rows; Violet 27 Gloss "8.9" vs "8.5"; Re-solubility "2 vs 4" vs "1 vs 3"/"3 vs 3"). I report both as-is; the source is a single hand-typed/converted report, so values may be transcription-derived.
  • Only failed application-test reports exist in this drop ("#64 not ok", "#SAW 08020626 not ok"); absence of other reports does not mean other samples passed.
