Born for "agglomerates easily, hard to disperse"
NMTG-3278 is a super dispersant dedicated to carbon nanotubes (and nano carbon black), developed for the way they agglomerate easily and are hard to disperse.
Making nanoparticles "disperse from one another"
It has outstanding dispersion capability: nanoparticles are given enough force to disperse from one another, so agglomeration is avoided.
Stable · low viscosity · high concentration
It produces stable, low-viscosity and high-concentration carbon nanotube (nano carbon black) dispersion slurries — high nano content and low viscosity at the same time.
Physical and chemical properties (TDS)
Typical factory values; a COA test report accompanies every batch.
Product performance · five channels
All five performance channels are lit.
Ability to prepare nano material dispersion slurries with high nano content and low viscosity.
Effectively prevents nanoparticles from re-agglomerating, improving the storage stability of the nano dispersion slurry.
The nano dispersion slurry has a tight particle-size distribution.
APEO-free, zero VOC — an environmentally friendly product.
Raises high dispersion efficiency.
How to use · incompatibility demo
An anionic body: mixing in a cationic dispersant = charge neutralisation = failure or caking. Switch to view.
How to use
Add the appropriate amount of this nano-material super dispersant to the system, then grind or stir and adjust the system pH so the nano material disperses fully.
Recommended addition
Addition to the final plastic product; compatible with water-based / solvent-based systems.
⚠ Incompatibility warning
Never use together with a cationic dispersant! (Because this product is anionic, mixing them neutralises the charge and causes failure or caking.)

04Recommended dosage window
The documentation provides one statement on the addition of this product, with the denominator written in the sentence:

06How it differs from related grades
NMTG-3278 belongs to the carbon nanotube direction within the "conductive hyperdispersant" category. Three product lines coexist in the same category (plastic carbon black / carbon nanotubes / waterborne superconductive carbon black); select by target. Comparison as follows:
| Model | Data positioning (key points) | Primary target / direction | Dosage (as documented) |
|---|---|---|---|
| NMTG-3278 | Dedicated hyperdispersant for carbon nanotubes (nano carbon black); chemical dispersion (carbon nanotube debundling) | Dispersion of carbon nanotubes and nano carbon black (water / solventborne systems) | 0.5%—1% of the final plastic product |
| R1618 | Conductive carbon black hyperdispersant for plastics; chemical dispersion + conductive pathway construction | Plastic conductive carbon black direction | 0.5-2% by total carbon black weight; 0.5%—2% of the final plastic product |
| D3-A | Waterborne superconductive carbon black hyperdispersant (waterborne dispersion and adsorption) | Superconductive carbon black; immersion-type superconducting electronic products | 1-2% (by total formula weight); 5-8% (by total liquid amount) |
Interpretation note: The three models belong to the same "conductive hyperdispersant" category; their directions and targets are independent. Dosage denominators differ, so values cannot be applied interchangeably. (Data source: product handbook)
