Santechnol®PF6P-6107 OHPolymer is a silanol-terminatedpolydimethylsiloxane (OH-PDMS) with a viscosity range fromapproximately 750 to 20,000,000 cP at 25°C. It functions as a basepolymer for condensationcure RTV silicone systems. Its terminal silanolgroups provide reactive sites for crosslinking with multifunctionalalkoxy, acetoxy or oximino silanes, enabling formulation of both one-partand two-part moisture-curing silicone sealants.
