Fluorinated solvents play a vital role in aerospace and automotive manufacturing, providing the precision cleaning, defluxing, and surface preparation required for critical components where failure is not an option. From cleaning oxygen systems and hydraulic components to preparing surfaces for bonding and coating, fluorinated solvents deliver the performance, safety, and reliability that these demanding industries require.

The Aerospace and Automotive Cleaning Challenge

Aerospace and automotive applications require solvents that can:

• Clean Critical Components: Including oxygen systems, hydraulic systems, and fuel systems

• Ensure Safety: Non-flammable and compatible with sensitive materials

• Provide Precision: Remove contaminants at the microscopic level

• Meet Specifications: Comply with aerospace and automotive standards

• Be Environmentally Responsible: Low GWP and zero ODP

Key Aerospace Applications

Oxygen System Cleaning
HFC-43-10mee is used for oxygen system cleaning, where its non-flammability, low toxicity, and material compatibility are essential. Its blends are used for precision cleaning, defluxing flip chips and printed wiring boards, and oxygen system cleaning .

Precision Component Cleaning
ASAHIKLIN™ AE-3000 is used for precision cleaning of metals, alloys, composites, and plastics in aerospace applications, as well as for drying after cleaning with hydrocarbons or alcohols .

Avionics and Electronics Cleaning
Fluorinated solvents are used for cleaning avionics and electronic components, where residue-free drying and material compatibility are critical.

Key Automotive Applications

Electronic Component Cleaning
Fluorinated solvents are used to clean electronic components, including ECUs, sensors, and connectors.

Precision Component Degreasing
Fluorinated solvents effectively remove oils, greases, and waxes from precision automotive components.

Surface Preparation
Fluorinated solvents prepare surfaces for bonding, coating, and painting by removing contaminants.
