IOTA 231 is a low-viscosity, hydrogen-terminated linear phenyl silicone oil with low molecular weight and controllable reactivity. It can be used not only as a crosslinker but also for the modification of phenyl silicone resins and the preparation of high-performance composites, enhancing heat resistance, hydrophobicity, and mechanical strength of materials.
Low Viscosity (1–10 mm²/s): Good flowability, easy mixing and impregnation.
Controllable Reactivity: Si-H bonds can undergo hydrosilylation with alkenyl groups under platinum catalysis under mild conditions.
Phenyl Functional Groups: Imparts better thermal stability and UV aging resistance to modified materials.
Good Dilutability and Compatibility: Can be blended with various silicone resins and oils.
