Physical Properties

Product Application Range

Surface activation and modification for various inorganic fillers (such as calcium carbonate, wollastonite powder, talcum powder, starch, kaolin, bentonite, steatite powder, gypsum powder, fly ash, palygorskite, aluminum oxide, etc.), inorganic flame retardants (such as magnesium hydroxide, aluminum hydroxide, zinc borate, antimony trioxide, etc.), and pigments (such as ferric oxide red, zinc white, titanium dioxide, zinc oxide, lithopone, etc.). The modified fillers, flame retardants, and pigments are suitable for composite products such as plastics, rubber, coatings, inks, laminates, and adhesives.

Features and Application Effects

Inorganically modified powders treated with an aluminum acetate coupling agent offer stable quality, light color, non-toxicity, minimal taste, and synergistic thermal stability and lubricity with resins. They have a broad application range, require no diluents, are easy to use, and are cost-effective.

2. Various inorganic powders treated with an aluminum acetate coupling agent for activation and modification, as their surface undergoes chemical or physicochemical reactions, form an organic molecular layer, changing from hydrophilic to organophilic. Practice has proven that when the surface of inorganic powders is modified with an aluminum acetate coupling agent for use in composite products, the coupling agent's hydrophilic end and organophilic end can separately react with the surface of inorganic fillers and organic resins, enhancing the interfacial compatibility between inorganic powders and organic resins. Therefore, modifying with an aluminum acetate coupling agent not only improves the processing performance of plastic products filled with inorganic powders but also significantly enhances the physical and mechanical properties of the products, reducing water absorption and oil absorption, and ensuring uniform dispersion of the fillers. For some low-filled plastic products, the filler content can generally be increased significantly (doubling or more than doubling the original content), improving processing performance (reducing melt viscosity and wear on molds), improving product quality, lowering production costs, and thus offering substantial economic benefits.

3. In the grinding process of pigment and ink, directly adding measured coupling agents can significantly improve the dispersibility of the pigment (filler), shorten the grinding time, enhance fineness and brightness, and reduce viscosity.
