​WACKER AK 500 Silicone Oil

WACKER AK 500 SILICONE FLUID is a low viscosity linear non-reactive polydimethylsiloxane in WACKER® AK series, designed for polyurethane mold release, industrial defoaming and electrical insulation. With high bond energy Si-O structure, it has excellent temperature resistance, low volatility and strong hydrophobicity, excellent fluidity and coatability, outperforming mineral oils.rong hydrophobicity

Features Of WACKER AK 500 Silicone Oil

  1. Low Viscosity & Easy Operation - Low viscosity, excellent fluidity, easy to add and coat, suitable for fine mold release processes

  2. Excellent Chemical Inertness - Non-reactive, resistant to acid, alkali and oxidation, good compatibility with most substrates and organic solvents

  3. Outstanding Wide Temperature & Weather Resistance - Stable at -60℃ to 300℃, resistant to radiation and high-temperature oxidation, not easy to degrade

  4. Low Volatility & Shear Resistance - Extremely low volatility, good shear stability, less loss and long service life during long-term use

Typical Applications Of WACKER AK 500 Silicone Oil

  1. Polyurethane Mold Release - Mold release for polyurethane products, easy peeling without sticking, ensuring smooth product surface

  2. Industrial Defoaming - Defoaming for anhydrous/low-water systems, fast bubble breaking and inhibition, suitable for various industrial scenarios

  3. Electrical Insulation Medium - Insulation for low-voltage electrical components, stable and reliable insulation performance in high and low temperature environments

  4. Textile Smoothing - Fabric smoothing agent, improving fabric hand feel and enhancing fabric water resistance
