Lipophilic fumed silica hardener and wear-resistant agent

Product type lipophilic fumed silica hardener and wear-resistant agent model
Product introduction lipophilic nano-silica powder is based on the chemical characteristics of different matrix materials, using special imported additives and nano-technology to process the powder The surface is modified in situ. The lipophilic nanosilica powder has better interfacial compatibility with the base resin, can be evenly dispersed in the base resin, and forms a tight combination with the polymer system, comprehensively improving the performance of the polymer material.
Product Features
The resin has good interfacial compatibility and resists agglomeration, which improves the decline in mechanical properties of composite materials caused by high filling.
Special surface treatment, self-flowing powder is beneficial to dispersion under shear, reduces the viscosity of the resin blend, and optimizes processing performance.
High temperature and low thermal expansion coefficient reduce the thermal expansion coefficient and curing molding shrinkage of composite materials, increase the thermal deformation temperature of polymers and product dimensional stability, alleviate the internal stress concentration of composite materials, and improve mechanical properties.
The excellent electrical insulation fluidization purification process greatly reduces the content of impurity ions, giving the composite material good insulation properties and arc resistance, and reducing the water absorption rate of the solidified product.
High strength improves the hardness, strength and wear resistance of composite materials, but attention must be paid to the wear and tear on equipment. It is recommended to carefully adjust the equipment operating parameters.
It has excellent weather resistance and migration resistance and is completely chemically inert. It will not change or induce deterioration in the presence of catalysts or multi-component systems, and will not decompose.

Instructions for use
Single use should be selected according to the performance requirements of the product, the particle size and The properties of composite materials are closely related. 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 with different particle sizes Filling can form dense filling in the polymer system at an appropriate ratio. A reasonable compound system can avoid the settling or floating of the filler, while reducing the viscosity of the resin blend under equal filling, which is beneficial to shear dispersion.
After silicon crystal powder is ultrafine, due to the increase in specific surface area, 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 ground moisture. During transportation, it must be waterproof and pressure-proof.
