D3-A

What it is. D3-A is a water-based super-conductive carbon black hyperdispersant: official category field 'Conductive Dispersant' (English category name 'Conductive Dispersant'), official one-liner 'Water-based system conductive, eco-friendly super-conductive' (English counterpart sentence 'Water-based conductive system'), mechanism field 'Chemical dispersion (water-based system conductive)'—its function is defined by dispersion in water-based systems of super-conductive carbon black, with adsorption and coating as well. Official overview sentence verbatim: 'D3-A hyperdispersant is improved by our company on the basis of D3, a water-based hyperdispersant and adsorbent developed specifically for immersion of electronic products with super-conductive carbon black. It is a low-molecular-weight solution compounded from a hyperdispersant for carbon nanotubes and non-ionic R900 hyperdispersant plus D3 in precise proportions under low temperature and low pressure conditions. It has excellent molecular weight and a fairly narrow molecular weight distribution, and has very good dispersibility and conductive effect for the distribution of super-conductive carbon black in aqueous solution.'

Name and spelling. Handbook layer: page title 'D3-A Super-conductive Carbon Black Dedicated Hyperdispersant', table of contents line 'D3-A: Water-based Super-conductive Carbon Black Hyperdispersant', company introduction list sentence 'Water-based Conductive Carbon Black Hyperdispersant: D3-A'. Official full name 'Water-based Super-conductive Carbon Black Hyperdispersant D3-A', English name 'Aqueous Conductive Dispersant D3-A', Traditional Chinese name 'Water-based Super-conductive Carbon Black Hyperdispersant D3-A'; official website list title (Chinese) 'Super-conductive Carbon Black Dedicated Hyperdispersant', (English) 'Hyperdispersant for super-conductive carbon black'. Detail page layer: main title 'Super-conductive Carbon Black Dedicated Hyperdispersant', subtitle 'Ether polymer · Dedicated to immersion of super-conductive electronic products · Water-based hyperdispersant and adsorbent', header 'TECHNICAL DATA SHEET · TDS-D3-A · REV 2026-09 · CN', navigation label 'Super-conductive carbon black · TDS'. (Data source: product handbook / official product data)

Attribution and coordinates. Handbook layer: listed within the hyperdispersant series section of the product catalog (adjacent rows in the catalog: above 'R1848: Special Encapsulation-Type Hyperdispersant', below 'NMTG-3278: Carbon Nanotube Hyperdispersant'). Official layer: series attribution is the hyperdispersant series (list position 9, preceded by R1848, followed by NMTG-3278); application domains are registered in two layers—coatings and inks domain and special function domain; industry-side mapping is the organic-inorganic powder category. (Data source: product handbook / official product data)

What it is not. It is not the plastic conductive carbon black direction R1618 in the same category; not the carbon nanotube direction NMTG-3278 in the same category; not the conductive leather antistatic direction DD550 adjacent in the 'D'-starting numbering (category 'antistatic agent'); not a masterbatch / resin / filler itself; except for the explicitly recorded R810 immersion-type combined use, the materials do not write it as a replacement, upgrade, or derivative relationship for any model. (Data source: product handbook / official product data)

Data boundaries. The materials give the overview sentence, advantages paragraph, main ingredients, five performance indicators, uses, recommended dosage, and packaging; they do not list storage conditions, shelf life, transport, usage method, processing temperature window, safety notes, disclaimers, or test methods; the values below are values recorded in the materials, not performance commitments. (Data source: product handbook / official product data)

Composition. The handbook 'Main ingredients' verbatim 'ether polymer', and the official ingredient field is from the same source with the same value—specific grade, polymerization structure, and compounding ratio are not given in the materials and are not presumed. (Data source: product handbook / official product data)

Advantages paragraph (verbatim transcription). Full paragraph verbatim: 'D3-A hyperdispersant is a water-soluble high-efficiency hyperdispersant, with low dosage, and has very good dispersibility, adsorption, and conductive effect for super-conductive carbon black. For example, when producing super-conductive carbon black ultrafine powders, the finer the powder, the more likely it is to agglomerate, seriously affecting product quality, and when dissolved in water, it is prone to not dispersing, sedimentation, and similar phenomena. However, adding D3-A hyperdispersant can quickly disperse super-conductive carbon black in aqueous solution, and form a coating layer on the surface of super-conductive carbon black powder, and does not affect conductive performance.' Five key points: water-soluble and high-efficiency, low dosage; combines dispersion, adsorption, and conductive effects; directly addresses the agglomeration and sedimentation dilemma of ultrafine powders; rapidly disperses after addition; coating does not affect conductivity. All are qualitative statements. (Data source: product handbook)

Compounding lineage (overview sentence and detail page lineage layer). The overview sentence (quoted above) already records the source path: D3 base + hyperdispersant for carbon nanotubes compounded with non-ionic R900 hyperdispersant, made into a low-molecular-weight solution under low temperature and low pressure. Detail page 'SEC.01 / LINEAGE' block title 'Core Overview and Compounding Lineage': three nodes 'Hyperdispersant for carbon nanotubes / Non-ionic R900 hyperdispersant / D3 base' → 'Low-temperature low-pressure compounding · precise ratio' → 'D3-A · low-molecular-weight solution'. Reading: the lineage diagram is a graphical expression of the overview sentence, not a feed formula; the ratio is not given in the materials and is not presumed. (Data source: product handbook / official product data)

Detail page mechanism layer (page-based presentation). 'SEC.02 / SEDIMENTATION TEST' block title 'Dispersion · Coating · Conduction Triple Verification', block note verbatim 'Switch mode: without D3-A, carbon dots settle and clump; after addition, they suspend uniformly, a pale yellow coating ring forms, and the cyan conductive pathway remains connected.'; three-step cards: 'DISPERSE / Rapid dispersion' (the aqueous-phase challenge of super-conductive carbon black: poor dispersion, easy sedimentation; rapid dispersion after addition), 'COAT / Surface coating' (high-efficiency coating layer on powder surface: prevents sedimentation, no agglomeration), 'CONDUCT / Conduction unaffected' (dispersion and conduction achieved together: does not affect its conductive performance). Reading: the switch demo and pathway animation are interface presentations, not measured data, and are not cited as indicators. (Data source: official product data)

Effect boundaries. The overview, advantages paragraph, and mechanism field are all directional statements: no resistivity, no quantified dispersion efficiency value, no comparative data. This page does not extrapolate or make commitments. (Data source: product handbook / official product data)

[Key physicochemical indicators] five items verbatim (primary basis) (Data source: product handbook)

Reading note. ① The five items are transcribed verbatim by layer; do not merge wording differences between layers ('0.95g/ml' ↔ '0.95 g/ml'; '2.9-3.4' ↔ '2.9 – 3.4'; '53-81mPas' ↔ '53 – 81 mPa·s'; appearance written continuously ↔ written separately with three punctuation marks); ② this grade has no other physicochemical items such as solids content, do not fill the position by borrowing from other grades; ③ each of the five items has only one set of values, no multiple values coexist; ④ the appearance wording is transcribed verbatim from the source sentence (handled according to the original). (Data source: product handbook / official product data)

Conclusion first: two dosage lines coexist (each denominator is stated separately) ⇒ present both lines, do not choose only one, do not convert across lines. Layer-by-layer verification as follows. (Data source: product handbook / official product data)

Three points must be made clear. First, the two lines are parallel, not a single value—the objects and denominators are both different (superconductive silicon-carbon tube ↔ total formula weight; immersion-type superconducting electronic products ↔ total liquid amount), and the ranges are also different (1-2% ↔ 5-8%) ⇒ present both lines, do not choose only one, do not convert across lines. Second, the denominators are both stated: the official data layer simultaneously records the original text of both lines, and the two detail-page entries correspond one-to-one with the two lines. Third, this grade has no thickness-dosage direction clause—wording such as 'add more when thinner / add less when thinner' is absent from the source; do not write it, do not apply direction from other grades. (Data source: product handbook / official product data)

Demand-side note. The sample form example sentence on the detail page is verbatim: 'For example: superconductive carbon black does not disperse in water and settles on standing; would like to request a sample to test dispersion and encapsulation effect at 1%…'—1% falls within the 1-2% range and is a page example (not a recommended value, not a commitment); in practice, request the accompanying technical documents by item number and conduct a small-scale trial. (Data source: official product data)

Object system. Objects = superconductive carbon black (ultrafine powder and aqueous dispersion system) and immersion-type superconducting electronic products; the source [Application] sentence is verbatim: 'D3-A hyperdispersant has a certain electrical conductivity, can make superconductive carbon black distribute evenly and does not affect the conductivity of superconductive carbon black. Mainly used for superconducting electronic products.' The usage form is an aqueous system (low-molecular solution). (Data source: product handbook / official product data)

Detail page application layer

Section title 'SEC.04 / DOSAGE', heading 'Applications and recommended dosage'; the two application lines correspond one-to-one with the two handbook lines; the form has four checkbox items: 'superconductive silicon-carbon tube / immersion-type superconducting electronic products / superconductive carbon black aqueous dispersion / other superconducting electronic materials'. (Data source: official product data)

Official domain coordinates

Application domain is registered at two layers—coatings and inks domain and special function domain; the industry-side mapping is the organic/inorganic powder category. (Data source: official product data)

Boundaries

D3-A governs the aqueous-system dispersion of superconductive carbon black (including adsorption and encapsulation for immersion-type superconducting electronic products), and is not the same as plastic conductive carbon black (R1618), carbon nanotubes (NMTG-3278), water-based carbon black ('water-based carbon black dedicated dispersant R400'), or dye dispersion (R780). On the masterbatch side: no corresponding entry for this grade, nor an 'internal use'-type mapping, is seen—write 'no correspondence'; do not infer. (Data source: product handbook / official product data)

Field issues & application examples (as recorded in the source material)

Conclusion first. The items most likely to be associated by number are R1618 / NMTG-3278 (three parallel lines in the same category 'conductive hyperdispersant'); next is DD550, adjacent by initial 'D'; then there is the base name 'D3' appearing in the overview sentence (not an independently registered grade). Each is independent, not written as a parent-child code or substitution relationship — values are not copied between them. (Data source: product handbook / official product data)

Reading note: the comparison only explains each item's source positioning and applicable target; values for different grades must not be applied interchangeably; identification is based on the official full name and category field. (Data source: product handbook / official product data)

The following points come item by item from source records; items not listed in the source are not drafted on this page.

The data on this page come from two types of sources and can be traced item by item:

• Two types of factual sources: product handbook (main volume / edited version / hyperdispersant series special volume, mutually corroborating text) and official product data (product fields, series catalog and application-domain data, detail page copy), with sources noted alongside the text and traceable item by item.
• Section 6 cross-reading: name, category, composition, mechanism, recorded values, and dosage system are taken item by item from each item's own page records; values for different grades are not written into each other's paragraphs.
• All values on this page are source-recorded values; for actual production, please confirm by small-scale trial in combination with your own formulation, carbon black system, and processing conditions.

Not covered by the source material (not written on this page — to be added later)

• Dosage two lines juxtaposed: the handbook layer's two lines (1-2% based on total formulation weight / 5-8% based on total liquid amount) coexist, with denominators stated separately ⇒ both lines are presented side by side, not choosing one over the other; it is recommended that the source side supplement the applicability notes for the two lines.
• Storage clause missing: the four sources and the detail page layer have no storage clause ⇒ not drafted; it is recommended that the source side review and supplement the record.
• Wording in the advantages paragraph: the character romanized as 'rong' in the phrase romanized as 'dang rong yu shui shi' is as in the source, transcribed verbatim, not changed on its behalf.
• Compounded composition terms: 'D3', 'hyperdispersant for carbon nanotubes', and 'nonionic R900 hyperdispersant' are descriptive terms for compounded composition in the overview sentence — transcribed verbatim, not expanded into independent product relationships, and not used as a basis for calculation.
• R810 compatibility value: 'R810 (dosage 2%)' is a compatibility-use value recorded in the source, not a component of this grade's dosage; this page transcribes it verbatim and does not expand it into an independent product relationship.
• Page interactions are not used as indicators: the immersion toggle demonstration and conductive path animation are interface presentations ⇒ not cited as indicators; the two-state reading text issue has been logged, and this page does not cite its wording.
• Similar-looking number note: R1618 / NMTG-3278 (three lines in the same category); DD550 (adjacent number starting with 'D'); 'D3' (base name, not a grade) — for search and selection, the official full name and category field shall prevail.
