Dissolubility: dissoluble in isopropanol, methylbenzene, xylene, white oil, DOP and other organic solvents, can’t dissolute
in water, but can emulsify in water
Third, main applications
1、 composite materials
When dealing with fillers like calcium carbonate and argil it can improve the impact strength and fluidity of composite materials.
Filling with carbon black can enhance the conductivity of composite materials and the applicable resins include
semi-rigid and rigid polymers like PVC、PP、nylon.
2、 coatings
When used in coating industry it can improve the dispersion and anti-settling of inorganic fillers (for example:white carbon black) in polymers.
It also can increase the filling amount in coatings and the ability of watertightness, fire prevention and corrosion prevention.
3、 coupling
Not only can this product apply to the coupling between inorganic fillers and organic resins, but also the coupling among
different polarities of organic resins.
