CAS 185045-85-6 is a self-developed, high-performance azeotropic mixture designed as a direct functional replacement for 3M Novec 71IPA. This clear, colorless fluid consists of a proprietary hydrofluoroether (HFE) combined with isopropanol (IPA). It is engineered for precision cleaning where surface tension and wetting are critical. CAS 185045-85-6 provides excellent solvency for light oils and ionic contaminants while maintaining the safety and environmental benefits of fluorinated solvents. It is non-flammable and stable in vapor degreasing applications.

• Direct Replacement for Novec 71IPA: Perfectly matched for existing vapor degreasing processes requiring a mild, alcohol-enhanced fluorinated solvent.

• Enhanced Cleaning Power: The integrated IPA component effectively removes fingerprints, light oils, and polar contaminants that pure HFEs cannot.

• Non-Flammable & Stable: The azeotropic composition ensures the fluid maintains a constant boiling point and remains non-flammable during use and storage.

• Zero ODP & Low GWP: Environmentally sustainable formula that complies with global phase-down regulations for ozone-depleting and high-GWP substances.

• Ultra-Low Surface Tension: Ensures deep penetration into tight spaces and complex geometries for thorough cleaning and spot-free drying.

• Self-Developed Quality: Chemfine controls the synthesis process to guarantee ultra-low non-volatile residue (NVR), critical for aerospace and medical electronics.

Precision Electronic Cleaning

Ideal for removing light fluxes, ionic residues, and handling soils from printed circuit boards (PCBs) and electronic assemblies.

Optical Component Cleaning

Used for degreasing and cleaning lenses, mirrors, and fiber optic connectors without leaving residue or damaging delicate coatings.

Medical Device Manufacturing

Provides safe, effective cleaning for surgical instruments and medical electronic hardware where biocompatibility and cleanliness are paramount.

Vapor Degreasing & Drying

Optimized for use in vapor degreasing equipment as a rinsing and drying agent, providing a spot-free finish on metal and plastic parts.

Aerosol Solvent

Can be formulated into aerosol cleaners for "on-the-spot" precision cleaning and maintenance of electrical equipment.

Standard industrial packaging options for CAS 185045-85-6 include:

• 20kg or 25kg specialized high-purity HDPE or fluorinated pails.

• 250kg UN-certified internally coated steel drums.

• ISO Tanks for bulk international maritime logistics.

• All containers are hermetically sealed and nitrogen-blanketed to preserve azeotropic integrity and moisture-free status.

CAS 185045-85-6 should be stored in a cool, dry, and well-ventilated warehouse. Keep containers tightly sealed to prevent evaporation of the azeotropic components. While non-flammable, store away from extreme heat and direct sunlight. Keep away from strong acids and strong bases. Properly stored, it has a shelf life of 24 months.
