Primary Chemistry:
Halocarbon® MT-3I is a premium-quality polychlorotrifluoroethylene (PCTFE) grease thickened with a high-molecular-weight polytetrafluoroethylene (PTFE) powder to achieve medium viscosity.
Halocarbon® MT-3I is a specialty fluorinated grease formulated from polychlorotrifluoroethylene (PCTFE) and engineered for demanding lubrication and sealing applications where chemical resistance, thermal stability, and material compatibility are critical. Thickened with a high molecular weight polytetrafluoroethylene (PTFE) powder and enhanced with anti-rust additive, this grease has a moderate viscosity of 300 cSt at 40°C. It maintains consistent film strength and lubrication across a wide temperature range. Halocarbon® MT-3I is especially recommended for thread lubrication and sealant application and helps to prevent galling.
Thermal stress and fluid degradation in high-temperature conditions
High volatility of traditional fluids such as hydrocarbons, silicones, etc.
Poor safety properties of other lubricants and fluids containing hazardous ingredients
Poor material compatibility of fluids with plastics, polymers, metals, or elastomers
Reduced operational efficiency from the chemical breakdown of fluids
Rust or corrosion of equipment parts
Breakdown of lubricants and fluids in reactive chemical systems
Hazardous reactions in oxygen, chlorine, or other reactive gases
Seizing galling, or threaded connections, from improper lubrication
Thread lubrication
Sealant applications
