| Silicone OH Polymer (Base Polymer) |
| 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. | ||
| Low viscosity fluids (SiSiB® OF0025, PF1070, 25cSt. – 750cSt.) Middle viscosity fluids (SiSiB® PF1070, 1000cSt. - 10000cSt.) High viscosity fluids (SiSiB® PF1070, 20000cSt. - 150000cSt.) |

| SiSiB® PF1071 | ALKOXY TERMINATED SILICONE POLYMER | -- |
| 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. | ||
