Silicone fluids / Silicone spray

High thermal resistance

WACKER silicone fluids are crystal-clear liquids that range in viscosity from 0.65 to roughly 1,000,000 mm2/s and have unique properties that stem from their molecular structure. The high-quality silicone fluids are polydimethylsiloxanes (PDMS) consisting of alternating silicon and oxygen atoms with their remaining valences satisified with methyl groups (-CH3).

The AK silicone fluids are notable for their high thermal resistance over a wide range of temperatures from -60 to +200 °C. They are also used as process auxiliaries for diluting RTV-2 silicones to reduce the viscosity of non-crosslinked RTV-2 silicones while simultaneously reducing the Shore hardness.
Silicone Spray AK is a universally-applicable release agents and lubricant for industry, model building and moldmaking, it is odorless and CFC-free. In pure, undiluted form, it is a high performance raw material exhibiting a wide range of properties. Easily recognizable as a crystal-clear, hydrophobic silicone film, with very good release and lubricity properties and a thermal stability up to approx. +180 °C.
