According to Hendrik Ahrens, R & D manager for coatings in the Functional Chemical Division of Clariant Produkte (Deutschland) GmbH, dispersing agents
overcome compatibility constraint experiences with the three major coating components--pigments, resins, and solvents.
Two different approaches have been tested: a "classical" approach which involves the introduction of the dispersing agent
during the melt mixing, and an "innovative" approach, consisting in the immobilization, either covalent or non-covalent, of phPOSS molecules onto CNTs surface.
It was also observed that dispersing agent
facilitated the formation of CSH gel.
Asia-Pacific dominates the dispersing agent
market, followed by Europe and North America.
alumina in saline water) without having to employ an additional dispersing agent
, the waste liquid can simply be recirculated back through the device and used again and again.
Washington, June 15 (ANI): Scientists have discovered new properties of graphene oxide, which could see the material being used as a dispersing agent
for insoluble materials, like carbon nanotubes.
The reaction scheme for the various steps as described above for synthesizing a representative dispersing agent
, DA 87, is depicted in Fig.
An anionic dispersing agent
is added to the graphite dispersion.
The surprising thing about this work is that the dispersing agent
can simply be the natural organic matter in the water," comments Mason B.
To prevent pipelines from becoming blocked by hydroxides, IFP has also developed a new dispersing agent
, called Emulfip 102b, which has proved cost-efficient and environmentally-friendly.
The sand is then pretreated for five minutes with water and a dispersing agent
in a high-speed mechanical stirrer to loosen the clay before performing the clay wash.
To achieve good pigment stabilization, the dispersing agent
must be able to adsorb onto the surface of the pigment.
