Our products are widely used in formulation of condensation curing silicone sealants.
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® PF1071 | 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. ALKOXY TERMINATED SILICONE POLYMER |
