Usage
Ultra-high temperature specialty lubricants: Exhibit excellent thermal stability, radiation resistance, and extremely low vapor pressure. Widely used as ultra-high temperature lubricants, vacuum pump oils, and damping fluids in aerospace, nuclear industry, and vacuum environments.
Electronic connector protectants: Used on the surfaces of precious metal electronic connectors and tactile switches. Forms an ultra-thin protective film to prevent contact surface wear, oxidation, and arc burns, significantly extending connector life.
Optics and instrumentation: Its high refractive index and radiation resistance also make it suitable as a coupling agent or coating for special optical instruments.
Packing
25kg/drum, or customized into smaller packaging sizes based on customer requirements.
Storage
Store in a cool, dry, and well-ventilated warehouse. It possesses extreme chemical stability and resistance to degradation; however, containers must be kept tightly sealed to protect against moisture and cross-contamination.
