Hydrophobic ultra-fine silica powder is based on the chemical properties of different matrix materials, using special imported additives and processes to conduct in-situ surface treatment of the powder. Modified. Hydrophobic ultrafine silica powder has better interfacial compatibility with the base material resin, can be evenly dispersed in the base material resin, and forms a tight combination with the polymer system to comprehensively improve the performance of the polymer material.

Instructions for use
Individual use should be based on the performance of the product It is required to make a selection. The particle size is closely related to the performance of the composite material. The smaller the particle size, the better the surface fineness and the more significant the enhancement effect. However, the viscosity will also be greater during blending. Please carefully adjust the formula to balance various properties.
Mixing filling with different particle sizes can form dense filling in the polymer system at appropriate proportions. A reasonable compound system can avoid the settling or floating of the filler, and at the same time reduce the viscosity of the resin blend under equal filling, which is beneficial Shear dispersion.
As the specific surface area increases, it is easy to agglomerate, has poor compatibility with polymers, and is difficult to disperse evenly, affecting the physical properties of composite materials. Interfacial compatibility between hydrophobic micro-silica crystal powder and polymers Good. The surface coating layer can produce a bonding reaction with the groups of the base resin, reduce the viscosity of the blend, eliminate interface stress concentration, and improve the mechanical properties of the composite material. Different models of hydrophobic products have different surface groups in the resin. The applicability of the system will be slightly different. It is recommended to evaluate carefully or contact our company.
It is recommended to determine the optimal addition amount through experiments.
Precautions
This product should be stored in a cool, dry and ventilated place place to prevent moisture on the ground. It should be waterproof and pressure-proof during transportation, and be loaded and unloaded with care during transportation to prevent damage to the packaging. When the relative humidity of the environment exceeds, avoid exposure to the air, and if necessary, bake it (℃) before use. After use, sealing and moisture-proof measures should be taken. It is recommended to use the package after unpacking
