TMC-705 is a \u003cstrong\u003esingle-component (pentaphenyl trimethyl trisiloxane) clear fluid\u003c\/strong\u003e that is chemically equivalent to \u003cstrong\u003eDow Corning® DC-705\u003c\/strong\u003e. This methylphenyl silicone fluid is designed to provide superior resistance to oxidation, heat, and chemicals while enabling prolonged and stable operation in demanding vacuum pump environments.\u003c\/p\u003e\n\u003cp\u003eTMC-705 Diffusion Pump Fluid is specifically formulated for \u003cstrong\u003ehigh-vacuum oil diffusion pump applications\u003c\/strong\u003e. Its resistance to oxidation, heat, and chemical exposure helps maintain reliable performance during operation. The fluid does not crack under heat or when exposed to intake gas, unlike petroleum and fatty acid ester pump oils. It also does not emit oxidation gas or produce acid, tar, pitch, or other substances when the vacuum is broken during heating, making it suitable for prolonged and stable vacuum pump operation.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cp\u003eThe TMC-705 Diffusion Pump Fluid offers the following product features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSuperior oxidation, heat, and chemical resistance.\u003c\/li\u003e\n\u003cli\u003eDoes not crack under heat or when exposed to intake gas, unlike petroleum and fatty acid ester pump oils.\u003c\/li\u003e\n\u003cli\u003eDoes not emit oxidation gas.\u003c\/li\u003e\n\u003cli\u003eDoes not produce acid, tar, pitch, or other substances when the vacuum is broken during heating.\u003c\/li\u003e\n\u003cli\u003eEnables prolonged and stable operation of vacuum pumps.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cp\u003eTMC-705 is intended for:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-vacuum oil diffusion pump applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIt is used in vacuum pump applications where prolonged and stable operation is required.\u003c\/p\u003e\n\u003ch2\u003eMaterial Compatibility\u003c\/h2\u003e\n\u003cp\u003eTMC-705 is compatible with most materials.
