Solvents and Alcohol

Solvents play a vital role in aircraft maintenance by facilitating the cleaning, degreasing, and preparation of surfaces for repairs or coatings. Commonly used solvents include isopropyl alcohol, acetone, mineral spirits, methyl ethyl ketone (MEK), toluene, methanol, and naphtha, each selected for its specific properties and compatibility with aircraft materials. Isopropyl alcohol is widely used for cleaning avionics and sensitive components due to its rapid evaporation and non-corrosive nature. Acetone and MEK are effective in removing adhesives and tough residues, while mineral spirits and naphtha are often employed for degreasing and general-purpose cleaning. Toluene and methanol find niche applications but require careful handling due to their toxicity and flammability. The use of these solvents is governed by strict safety protocols to protect personnel, ensure material compatibility, and minimize environmental impact, underscoring their importance in maintaining aircraft performance and reliability.
