C111 Pigment Carbon Black

C111 (printed as C111B/P on the pigment TDS) is a channel-process pigment carbon black. Suffix B is beaded / granular; suffix P is powder. Channel grades sit in a different process family from furnace pigment rows such as P1550. CAS No. 1333-86-4 · H.S. Code 2803000000 · general chemical grade.

C111 channel-black specifications

Taken from the C111B/P row of the DLcarb pigment carbon black TDS (printed 3 August 2025):

Technical specifications (TDS)
DLcarb Industry Co., Ltd
Product	Pigment carbon black	Grade	C111B/P
No.	Item	Unit	Specification
1	Oil absorption	ml/100g	100±10
2	Iodine / surface area (channel)*	g/kg	200±20
3	Heating loss	%	≤1.5
4	Ash content	%	≤0.5
5	Tinting strength	%	≥130
6	pH	-	2.5±1
7	45 μm sieve residue	ppm	≤50

*TDS footnote: for channel-process grades, this column reports specific surface area rather than iodine absorption. The unit printed in the table header remains g/kg; we keep that as published and do not convert it to m²/g.

Note: figures above are TDS specification ranges for reference. Delivery specifications follow the technical agreement we confirm with you. Please validate the grade in your own formulation and process. Safety information sits in the SDS (EU REACH), not in the TDS table.

Coatings and ink systems marked for C111

The application map marks C111B/P for:

• Water-based paints, water-based inks, water-based coatings and water-based color pastes
• Solvent-based paints, solvent-based inks, solvent-based coatings and solvent-based color pastes
• Powder coatings

It does not mark C111 for plastics, masterbatch, rubber, silicone, wire, cable or sponge. Those uses belong to other columns — P1550, for example, is checked for plastics, masterbatch, sponge, sealants and epoxy systems, but not for solvent-based coatings or powder coatings. See also how to select pigment carbon black and coatings and inks: dispersion and jetness.

Why the iodine column is labelled differently

On furnace pigment rows the second numeric column is iodine absorption. On channel rows the TDS footnote redirects that column to specific surface area. For C111 the printed figure is 200±20. Combined with oil absorption 100±10 ml/100g, tinting strength ≥130% and pH 2.5±1, that is the channel-grade fingerprint on this sheet — distinctly more acidic than furnace rows such as P1550 (pH 7~9).

Alongside the TDS we publish an EU REACH SDS for carbon black (CAS 1333-86-4) and three SGS reports dated 26 June 2026 on a submitted carbon black sample: REACH Candidate List SVHC screening (253 substances, results ≤0.1% w/w, plus one potential SVHC also ≤0.1% w/w); EU RoHS Directive (EU) 2015/863 amending Annex II to 2011/65/EU (Pass); and halogen testing to IEC 62321-3-2:2020 (fluorine, chlorine, bromine and iodine reported ND on that sample; MDL 20 mg/kg for F and 50 mg/kg for Cl, Br and I). Those reports describe the submitted sample — they are not a substitute for the grade TDS or a lot COA. C111B/P is not named as its own model number on the SDS service summary; the SDS is the carbon-black document for this chemistry. Ask us if a customer file needs that stated explicitly.

The TDS storage note is the same across these sheets: keep the material in a cool, dry, well-ventilated warehouse; protect it from moisture; guard against dust inhalation and skin contact; store it apart from strong oxidants and do not mix-store. For classification and safe handling, follow the SDS rather than the short TDS footnote. MOQ and Incoterms are not published here.
