Aluminate coupling agent can improve the affinity and binding force between inorganic filler and organic polymer, thus producing anti-sedimentation effect and improving the bonding strength. Compared with other coupling agents (such as titanate, borate, etc.), the inorganic powder activated by aluminate coupling agent not only has stable quality, but also has light color, non-toxic, small taste and synergistic thermal stability and lubricity for PVC. It has a wide range of applications, no need for diluent, easy to use and low price.

• ● It is suitable for surface activation modification of various inorganic fillers (such as calcium carbonate, wollastonite powder, talcum powder, kaolin, bentonite, gypsum powder, alumina, etc.), inorganic flame retardants (such as magnesium hydroxide, aluminium hydroxide, zinc borate, antimony trioxide, etc.) and pigments (such as iron oxide red, zinc barium white, titanium dioxide, zinc oxide, lithopone, etc.).
• ● Modified fillers, flame retardants and pigments can be applied to composite products such as plastics, rubber, coatings, inks, laminates and binders.
