Hydroxy Silicone Oil 500cst CAS 70131-67-8 Medium Viscosity Crosslinker for Condensation RTV
Hydroxy Silicone Oil 500cst CAS 70131-67-8 is medium viscosity hydroxyl-terminated polydimethylsiloxane (OH-terminated PDMS).
With reactive terminal hydroxyl groups, it can undergo polycondensation reaction with various silane crosslinkers in the presence of catalyst. It serves as the fundamental base polymer for manufacturing single-component and two-component condensation type RTV silicone sealants, adhesives and coating materials.
Hydroxy Silicone Oil 100cst CAS 70131-67-8 Low Viscosity Structure Control Agent for HTV Rubber
Hydroxy Silicone Oil 100cst CAS 70131-67-8 is low viscosity hydroxyl-terminated polydimethylsiloxane (OH-terminated PDMS).
It can react with silanol groups on the surface of silica filler to restrain the hydrogen-bond structure between silica and silicone polymer. It significantly prevents the structuring phenomenon of HTV silicone rubber, enhances rubber plasticity and processing fluidity. It is an ideal structure control agent for high temperature vulcanized silicone rubber.
Hydroxy Silicone Oil 50cst CAS 70131-67-8 Low Viscosity OH Terminated PDMS for Silicone Resin
Hydroxy Silicone Oil 50cst CAS 70131-67-8 is low viscosity hydroxyl-terminated polydimethylsiloxane (OH-terminated PDMS).
It has high hydroxyl content, excellent chemical reactivity and narrow molecular weight distribution. It can carry out polycondensation reaction with silane monomers under proper catalytic conditions. It serves as a critical reactive raw material for the synthesis of methyl silicone resin, methyl phenyl silicone resin and other modified silicone resins.
