WACKER AK 5 Silicone Oil

WACKER AK 5 SILICONE FLUID is an ultra-low viscosity linear silicone fluid in Wacker’s AK series, designed for precision instrument lubrication, industrial rapid defoaming, low-voltage insulation, cosmetic texture improvement and textile smoothing. With high bond energy Si–O framework, it has wide temperature stability, strong hydrophobicity and low volatility, excellent fluidity and dispersibility.

Features Of WACKER AK 5 Silicone Oil

  1. Ultra-low viscosity & easy dispersion - Extremely fluid, easy to add and mix, suitable for fine formula processing

  2. Chemically inert & stable - Non-reactive, acid-alkali and oxidation resistant, compatible with most substrates and solvents

  3. Excellent wide-temperature resistance - Stable work from -60℃ to 300℃, radiation resistant and not easy to thermally degrade

  4. Low volatility & shear durability - Extremely low volatility, good shear stability, minimal loss in long-term use

  5. Superior surface performance - Low surface tension, hydrophobic and anti-stick, with both lubrication and smoothing effects

Typical Applications Of WACKER AK 5 Silicone Oil

  1. Precision lubrication - Lubrication of small precision instruments and electronic components, reducing friction loss

  2. Industrial defoaming - Rapid bubble breaking in anhydrous/low-water systems, suitable for chemical and pharmaceutical scenarios

  3. Low-voltage insulation - Insulation of low-voltage electrical components, stable performance in high and low temperature environments

  4. Cosmetic addition - Improve skin feel, enhance product smoothness and freshness

  5. Textile finishing - Fabric smoothing and anti-sticking finishing, improving hand feel and wearing performance
