Product Description

High Performance Tetramethyl Tetraphenyl Trisiloxane CAS 3982-82-9               ZINCA274                             
704 Diffusion Pump Fluid

It is a colorless transparent oily, single-component fluid designed for high vacuum of 10-7torr (untrapped). It performs well in tough, rugged applications and offers quick pump down, even after exposure to air at operating temperatures. ZINCA274 is thermally and chemically stable allowing it to keep pump jets free of tars and hard carbon.
