surface treatment
表面処理品タイトル

Although treatment using a coupling agent was the most effective way to solidify the interface between the filler and matrix resin, aggregation caused by treatment has been a big problem.
Admatechs has developed a revolutionary surface treatment process, enabling uniform surface treatment with minimal aggregation.

This series includes ADMAFINE silica and alumina surface modified using a microscopic special silicon compound.
Since fluidity, dispersibility, and cohesive property of particles are improved, compounds can be obtained with minimal variation in the batch when these particles are blended in resin.
Although the size of coarse particles removed is smaller than the conventional ADMAFINE, there is no increase in total cost owing to high fluidity and low cohesive property.


[Base ADMAFINE silica]
  Average particle size: 0.25, 0.5, 1.0, 1.5, and 2.0μm
  Coarse particle removal size: 3, 5, 24, and 45μm
  Purity: High-purity and regular

[Base ADMAFINE alumina]
  Average particle size: Approx. 0.7, 10, and 20μm
  Coarse particle removal size: 45μm
  Purity: High-purity and regular
