Scope of application :
suitable for surface activation modification treatment of various ultra-fine and nano-scale inorganic fillers (such as light and heavy calcium carbonate, magnesium hydroxide, alumina, barium sulfate, etc.) or pigments (aluminum silver powder, titanium dioxide), And in organic paints, inks and other products as a dispersant, anti-settling agent directly used.
Usage and dosage:
1. Dry modification treatment: the powder filler is mixed and heated by a high-speed kneader, and then directly or sprayed (better effect) metering coupling agent is added, and the treatment effect is achieved by high-speed stirring; or in the powder This product is added in the grinding and crushing process of the body production process, and the powder is subjected to surface modification treatment by mechanical chemical modification.
2. Integral blending method: In the production process of plastics, rubber and other products, the coupling agent can be added when the filler and the polymer are kneaded, the order of addition should be first filled with filler, coupling agent and a small amount of plasticizer, and then Add other components to form a composite material after molding.
3. Used directly as a dispersant in the production of paints, inks, and pigments.
4. The reference dosage of coupling agent is 0.5-2%, the specific dosage depends on the type of filler and products, production process and quality requirements.
