ShinEtsu HIVAC-G Silicone Sealant for Ultra-High Vacuum Systems

Basic Properties​

hinEtsu HIVAC-G is a high-vacuum sealing compound with refined silicone base oil and silica powder. Engineered for 10⁻⁶ Torr ultra-high vacuum environments, ideal for sealing, lubrication, and dielectric applications.

Product Description​

HIVAC-G minimizes outgassing via specialized refining, enabling long-term vacuum integrity. Exceptional thermal stability and chemical inertness resist plasma/acidic environments, reducing maintenance frequency.

Characteristics​

Application Scenarios​

emiconductor PVD Seals: Seals O-rings in deposition chambers. Maintains 10⁻⁷ mBar vacuum, implemented in Applied Materials Endura systems.
Particle Accelerators: Lubricates rotary seals in superconducting magnets. Withstands 10k cycles (zero particle release), used in CERN LHC.
Space Optics Assembly: Seals lens interfaces in space telescopes. Passes -80°C~150°C thermal cycling per NASA spec, applied in JWST.
