WACKER AK 600000 SILICONE FLUID is a high-viscosity linear silicone fluid in Wacker’s AK series, designed for polyurethane release, heavy damping, high-temperature sealing, material thickening and surface care polishing. With high bond energy Si–O framework, it has excellent thermal stability, strong hydrophobicity and great shear stability, superior to organic materials like mineral oils.
High viscosity & uniform film-forming - Extremely high viscosity, good film-forming, no loss in protection, suitable for long-term working conditions
Excellent chemical inertness - Non-reactive, acid-alkali and oxidation resistant, compatible with most non-polar systems
Wide-temperature stability & reliability - Stable work from -40℃ to 300℃, radiation and high-temperature oxidation resistant
Low volatility & outstanding shear resistance - Extremely low volatility, excellent shear stability, stable performance in long-term use
Comprehensive hydrophobic protection - Low surface tension, hydrophobic and anti-stick, with both lubrication and sealing effects
Polyurethane release - Release agent for polyurethane product molding, smooth demolding without affecting product surface gloss
Damping & buffering - Damping and shock absorption of large equipment and precision instruments, stabilizing vibration amplitude
High-temperature sealing - Sealing and gap filling in high-temperature working conditions, improving long-term sealing performance
Surface care & polishing - Surface care and polishing of metal and plastic, enhancing surface smoothness and texture
Material thickening - Thickening of coatings and adhesives, adjusting system rheological properties and improving use effect

Q1: What is the primary function of WACKER AK 600000 Silicone Oil in industrial formulations?
A: WACKER AK 600000 Silicone Oil is a high-viscosity, non-reactive polydimethylsiloxane (PDMS) fluid primarily used as a processing aid and surface modifier. It imparts excellent lubricity, improves substrate wetting, reduces surface tension, and helps suppress foam formation during manufacturing processes.
Q2: Is WACKER AK 600000 Silicone Oil suitable for use in food-contact or pharmaceutical applications?
A: This product is not pre-qualified for direct food-contact or pharmaceutical use. Customers must conduct their own regulatory evaluation and validation to confirm compliance with applicable local, national, or industry-specific requirements before deployment in such sensitive applications.
Q3: How should WACKER AK 600000 Silicone Oil be incorporated into formulations?
A: It is typically added during the late-stage mixing phase to minimize shear degradation and ensure uniform dispersion. Compatibility testing with other formulation components is recommended, as performance may vary depending on polarity, viscosity, and thermal stability of the base system.
Q4: Does WACKER AK 600000 Silicone Oil require special storage or handling conditions?
A: Store in original sealed containers at moderate ambient temperatures, away from direct sunlight and strong oxidizing agents. No special ventilation or personal protective equipment beyond standard industrial hygiene practices is generally required, though good workplace hygiene is always advised.
