Oleophilic fumed silica hardener and weare

  Product introduction lipophilic nano silica powder is prepared by in-situ surface modification of the powder with special imported additives and nano technology according to the characteristics of different matrix materials
Lipophilic nano silica powder has good interfacial compatibility with the base resin, can be evenly dispersed in the base resin, and closely combines with the polymer system to improve the performance of polymer materials

Product features
1
good interfacial compatibility with resin &mdash& mdash; Anti sedimentation, improve the decline of mechanical properties of composites caused by high filling

2
special surface treatment, powder self flowing &mdash& mdash; It is beneficial to the dispersion under shear, reduce the viscosity of the resin blend and optimize the processability

3
high temperature resistance, low coefficient of thermal expansion &mdash& mdash; Reduce the thermal expansion coefficient and curing shrinkage of the composite, improve the thermal deformation temperature of the polymer and the dimensional stability of the product, ease the internal stress concentration of the composite, and improve the mechanical properties

4
excellent electrical insulation &mdash& mdash; The fluidization purification process reduces the content of impurity ions, makes the composite have good insulation and arc resistance, and reduces the water absorption of the cured product

5
high hardness &mdash& mdash; Improve the hardness, strength and wear resistance of the composite, but pay attention to its wear on the equipment
It is recommended to carefully adjust the equipment operation parameters

6
weather resistance and migration resistance &mdash& mdash; It is inert and will not change or induce metamorphism in the presence of catalyst or multi-component system

Instruction for use
1
  The single use shall be selected according to the performance requirements of the product
The particle size is closely related to the properties of the composite
The smaller the particle size, the better the surface fineness and the better the reinforcement effect
However, the greater the viscosity during blending
Please carefully adjust the formula to balance various properties

2
  Using different particle size hybrid filling, dense filling can be formed in the polymer system at an appropriate proportion
The reasonable composite system can avoid the settlement or floating of filler, and reduce the viscosity of the resin blend with the same amount of filler, which is beneficial to shear dispersion

3
  After ultra-fine silicon powder, it is easy to agglomerate due to the increase of specific surface area and poor compatibility with polymer, so it is difficult to disperse uniformly, which affects the physical properties of the composites
Hydrophobic micro silicon powder has good interfacial compatibility with polymers
The surface coating can bond with the base resin groups, reduce the viscosity of the blends, eliminate interfacial stress concentration, and improve the mechanical properties of the composites
Due to the different surface groups of different types of hydrophobic products, the applicability of the resin system will be slightly different
It is recommended to carefully evaluate or contact our company

  It is recommended to determine the appropriate addition amount   through experiments;
