A VOC-free, dispersing agent
for water-based systems with benchmark performance in inorganic pigments, Dispex Ultra PX 4575 offers improved color development and lower viscosities in pigment concentrates containing transparent iron oxides and other inorganic pigments.
It is worth pointing out that an appropriate dispersing agent
needs to act on the surface of the powders that make up the compound, and to disperse on them in order to reduce the electric charge values, etc.
The disadvantage of solution-coating polymer powders is that a low-viscosity solvent is required to disperse the tubes, and, if water is used as the low-viscosity solvent, a dispersing agent
likely will be present in the final composite.
A general composition of given dispersing agent
The sample is prepared exactly as described for the autoclay method as far as drying, weighing into a tall-form 1000 ml beaker, and washing the sample with a high-speed mechanical stirrer and a dispersing agent
for five minutes.
The alkoxy-modified silsesquioxane compounds contain an alkoxysilane group that participates in an alkoxysilane-silica reaction as a silica dispersing agent
in rubber, with the release of zero to about 0.
In some beakers, the scientists added a dispersing agent
5% and better color characteristics were found when poly (ethylene glycol) was used as a dispersing agent
Polymeric dispersing agent
was first molten at 120 [degrees] C for 3 min, then the rotors were stopped, carbon black placed in the chute, a ram inserted with a 3 kg weight on top of it, and the rotors started again.
The wetting and dispersing agent
segment is expected to grow at a greater pace followed by the rheology modifiers and antifoaming agent segment.
BSI 189 is a low odor, zero VOC, greener alternative dispersing agent
for water-based systems approved under FDA (21 CFR) 176.
A process for preparing the organosilane masterbatch by mixing the rubber, filler, organosilane and dispersing agent
in an internal mixer or kneader, extruding and cutting into pieces.
