Product Introduction
Hydrophobic ultra-fine silica powder is produced by in-situ surface modification of the powder using special imported additives and processes based on the chemical properties of different matrix materials. 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.
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.
Application Reference
Silicone rubber (mold glue, handle glue, button glue and other copper-clad laminates, electronic potting glue, epoxy resin castables, plastic sealing materials, packaging materials, electronic components, high-performance adhesive agents, powder coatings, super-hard wear-resistant coatings, functional insulating coatings, anti-corrosion coatings, special paint inks, high heat-resistant resins and various functional polymer products.
Instructions for use
Individual use should be based on the product Select according to the performance requirements. 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 a dense filling in the polymer system at an appropriate ratio. 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 to shear dispersion.
After ultrafine silicon crystal powder is increased 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 the composite material. Hydrophobic micro silicon crystal The interface compatibility between the powder and the polymer is good, and the surface coating layer can produce a bonding reaction with the groups of the base resin, reducing the viscosity of the blend, eliminating interface stress concentration, and improving the mechanical properties of the composite material. Different models of hydrophobic products Due to different surface groups, the applicability of the resin 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 The product should be stored in a cool, dry and ventilated place to prevent ground moisture. 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 dry it if necessary. Bake (℃) before use. After use, sealing and moisture-proof measures should be taken. It is recommended to use it after unpacking
