Scope and dosage of aluminum ester coupling agent

Aluminum ester coupling agents are suitable for surface activation modification of various inorganic fillers (such as calcium carbonate, wollastonite powder, talc powder, kaolin, bentonite, gypsum powder, alumina, etc.), inorganic flame retardants (such as magnesium hydroxide, aluminum hydroxide, zinc borate, antimony trioxide, etc.), and pigments (such as iron oxide red, lithopone, 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 adhesives.

consumption

The dosage of aluminum ester coupling agent is generally about 0.5-2.5% of the filler, and the recommended dosage is 1%. The finer the particle size and larger the surface area of the pigment filler, the greater the amount of coupling agent used
