Application


  • Condensation cure one-part and two-part RTV systems are formulated from silanol terminated polymers with molecular weights ranging from 15,000 to 150,000. One-part systems are the most widely used. One-part systems are crosslinked with moisture-sensitive multi-functional silanes in a two stage reaction. In the first stage, after compounding with fillers, the silanol is reacted with an excess of multi-functional silane. The silanol is in essence displaced by the silane.


  • The reactivity of silanol fluids is utilized in applications other than RTV’s. Low viscosity silanol fluids are employed as filler treatments and structure control additives in silicone rubber compounding. Intermediate viscosity, 1000-10,000 cSt. fluids can be applied to textiles as durable fabric softeners. High viscosity silanol terminated fluids form the matrix component in tackifiers and pressure sensitive adhesives.


Packing and Storage


  • SiSiB® PF1070-10000 silanol terminated polydimethylsiloxane silicone based polymer is supplied in 190Kg steel drum or 950Kg IBC container.


  • In the original unopened packaging, SiSiB® PF1070-10000 OH polymer has a shelf life of 18 months in a dry and cool place.
