IOTA 3108 RTV Phenyl Silicone Gum, also known as α,ω Dihydroxy-Polydimethyl Diphenyl Siloxane or Phenyl Silicone Rubber Gum, is a versatile and high-performance material. Its molecular formula is represented as (CH3)2SiOH[(C6H5)2SiO]m[(CH3)2SiO]nOH. This colorless transparent oily liquid exhibits unique properties that make it suitable for a wide range of applications.

Technically, IOTA 3108 RTV Phenyl Silicone Gum is soluble in toluene, xylene, chlorinated hydrocarbons, and other organic solvents. It has a viscosity range of 2000-100000 mPa·s at 25°C and a phenyl content that can vary between 2.5-60.0 mol%. Additionally, its volatile content is limited to ≤ 5.0% when tested at 150°C for 2 hours.

In terms of applications, this product stands out due to its excellent electrical properties, weather resistance, ozone resistance, and low-temperature resistance. It also demonstrates remarkable radiation resistance, ablative resistance, and self-extinguishing capabilities. As such, IOTA 3108 RTV Phenyl Silicone Gum is ideal for use as a potting material for various electrical components. Furthermore, it can be utilized as impregnated impression and release materials, as well as a component in binders. Its versatility extends to bonding aircraft thermal insulation materials, spacecraft thermal insulation products, engine thermal insulation supplies, and nuclear power radiation protection coatings. For parts requiring cold and burn resistance, heat aging resistance, and radiation resistance, such as seals, pads, pipes, and bars, IOTA 3108 RTV Phenyl Silicone Gum is an excellent choice. Even at temperatures as low as -120°C, it retains its elasticity. When augmented with heat-resistant additives, it becomes suitable for special purposes such as ablative putty, coatings, and encapsulations.
