Application


  • SiSiB® HF2030 can be used as a reactive intermediate to make ABA organo-modified silicones via hydrosilations. Functional groups normally attached in this way include allyl terminated polyethylene or polypropylene glycols, amines, and epoxies.


  • SiSiB® HF2030 can be used as chain extender and crosslinker for addition cure liquid silicone rubber. It is used in conjunction with crosslinking hydrides to increase elongation and tear strength and lower durometer.


  • SiSiB® HF2030 can be used for water repellent treatment of textiles.


Packing and Storage



  • In the original unopened packaging, SiSiB® HF2030 has a shelf life of one year in a dry and cool place.
