Application


  • SiSiB® PC2640 can improve reinforcing properties of silicone fillers that contain hydroxyl groups.


  • SiSiB® PC2640 can improve physical and mechanical properties of vulcanizates. It can improve tensile strength, tearing strength and abrasive resistance and reduce compression set of vulcanizates. In addition, it can reduce the viscosity and improve the processability of silicone rubber products.


Packing and Storage


  • SiSiB® PC2640 organo silane is supplied in 200Kg steel drum or 1000Kg IBC container.


  • In the unopened original container SiSiB® PC2640 has a shelf life of one year in a dry and cool place.
