WACKER AK 20000 SILICONE FLUID is a medium viscosity linear non-reactive polydimethylsiloxane in WACKER® AK series, designed for polyurethane release, industrial lubrication and defoaming. With high bond energy Si-O structure, it has excellent temperature resistance, low volatility and strong hydrophobicity, with good fluidity and processability, outperforming mineral oils.
Medium Viscosity & Easy Processing - Moderate viscosity, good fluidity, easy to add and coat, suitable for various processes
Excellent Chemical Stability - Non-reactive, resistant to acid, alkali and oxidation, good compatibility with most substrates
Wide Temperature Resistance Range - Stable at -55℃ to 300℃, resistant to radiation and high-temperature aging
Low Volatility & Shear Resistance - Extremely low volatility, good shear stability, less loss during long-term use
Outstanding Release Effect - Suitable for release of polyurethane and other materials, easy to peel off, no impact on substrate performance
Polyurethane Release - Mold release for polyurethane products, improving demolding efficiency and ensuring smooth surface
Industrial Lubrication - Lubrication for general equipment and precision components, reducing friction loss and extending service life
Defoaming Application - Defoaming in anhydrous/non-polar systems, quickly inhibiting foam and improving product quality
Dielectric Application - Insulation for medium and low voltage electrical equipment, ensuring stable insulation at high and low temperatures
