Where do the AV 43.2 / amine 30.1 targets come from?21 Aug 03:31
I have everything needed. Here's the answer.
Where the AV 43.2 / amine 30.1 targets come from
The 43.2 (acid value) / 30.1 (amine value) pair is FOIL's internal reference standard for the product they call "9076" — not from the BYK vendor TDS. In every R&D review comparison table (LBN-21, 23, 24, 27…) it appears as the fixed "9076" standard column (Acid Value mg OH/g = 43.2, Amine value mgKOH/g = 30.1), and it is echoed verbatim as the target headers in the ELN summary sheet (
Two important cautions:
1. These are targets/reference values, not measured data — they are the spec the batches are judged against.
2. They are NOT the BYK-9076 vendor TDS. The public TDS gives *different* typical values: Amine value 44 mg KOH/g, Acid value 38 mg KOH/g. So the 43.2/30.1 pair should be labeled as FOIL's internal "9076" standard, while 44/38 are the vendor BYK-9076 reference.
3. There is a separate, third spec: ppt slide 5's "P-9076" design target (Acid 40, Sap 45, Amine 31, OH 35, Iodine 4.15, LOD 12%, P 0.75%), which differs again from both.
Gap note: No record in this drop states an explicit *origin/derivation* for 43.2/30.1 (e.g. a spec sheet or a measurement of a specific standard batch) — the provenance is their repeated, consistent appearance as the "9076" reference column and ELN target headers. The records do not name which physical batch produced those numbers.

aminev - 30.1, av - 43.2) and in each lab batch report's "Critical Parameters / Reference" rows. So the numbers trace back to the "9076" reference/standard column in the R&D review deck and the Old ELN SummaryReport (2) summary table, which the inventory confirms match each other exactly.Two important cautions:
