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
