Co-Formula Silane Coupling Agent for Surface Modification of Nano-powder

Nano powder has the characteristics of small particle size and large specific surface area, so it has unique small size effect, tunnel effect and surface effect. Therefore, it is favored for its excellent reinforcement, stability and thickening properties, and is widely used in plastics, rubber, coatings and other fields.

Due to the large surface energy of nano-powder, it is easy to agglomerate, which limits its ultra-fine effect, and it is difficult to disperse and infiltrate in the organic phase. Therefore, its surface modification must be carried out to improve its compatibility and bonding force with organic molecules.

Co-Formula silane coupling agent molecules are used to carry out a certain chemical reaction with the surface of the nano-powder, and the coupling agent is uniformly covered on the surface of the nano-powder. Thereby improving the hydrophobicity of nano-powder is a commonly used modification method of nano-powder.
