Main Uses

  1、KH-580 mercaptosilane coupling agent has sulfhydryl functional groups. As a metal surface antirust agent, KH-580 mercaptosilane coupling agent has special efficacy. It can enhance the corrosion resistance, oxidation resistance and adhesion with macromolecule such as resin when it is used to treat gold, silver, copper and other metal surfaces.
  2、In rubber industry, inorganic fillers such as silica, carbon black, glass fiber and mica are often used to improve the mechanical properties and wear resistance of rubber.
  3、It can be used in shrink-proof finishing of textiles.
