The silanol (-OH) terminated silicone polymer is the basis for the formulation of one-component, moisture curing RTV silicones and two-component, condensation curing RTV silicone compounds. The synthesis of silicone polymer is a multistep process beginning with elemental silicon.
SiSiB® PF1070 OH polymer are polydimethylsiloxanes with terminal silanol groups used as base polymers in condensation curing silicone elastomers. SiSiB® PF1070 OH polymer is available in differen viscosity levels.
SiSiB® PF1071 Polymer are Alkoxy functionalized silicone polymers, It can be formulated with the typical additives for condensation-type silicones (tin catalysts, silane-based adhesion promoters, plasticizers etc.). The amount of methoxy silane crosslinkers can be reduced to a great extent in this process as the polymer already carries the corresponding methoxy silane groups.
