  Typical Properties  

  Application  

PR-903 is a reactive and cross-linked silane coupling agent with sulfhydryl functional groups, which is widely used.

1. As a metal surface rust inhibitor with special effects, used to treat gold, silver, copper and other metal surface, which can improve its corrosion resistance, oxidation resistance and improve its adhesion to polymer materials.

2. It is widely used in filling polymer materials, and can be applied to thermosetting and thermoplastic polymer materials, such as epoxy, phenol sulfonate, polyvinyl chloride, polystyrene, polyinkstone, etc.

3. The effect is particularly good in the rubber industry, which can improve the mechanical properties of rubber, improve wear resistance, reduce permanent deformation, suitable for NR, EPDM, SBR, chloroether rubber, polysulfide rubber, styrene butadiene rubber, nitrile rubber, neoprene rubber and polyurethane rubber, especially suitable for light color products.

The suitable range of inorganic fillers is also very wide, can be used for glass fiber, white carbon black, quartz powder, talc, mica, fly ash clay, clay and other silicon-containing substances.

4. It can be used as a reinforcing agent and crosslinking accelerator for composite materials (such as resin-glass fiber composite materials), coatings, inks, glues and sealing materials.

5. It can be used for anti-shrink finishing of fabric in textile.
