What happens when nitrocellulose paint is exposed to a coat of engine oil?

• A. It remains unaffected and dries clear
• B. It will soften after a few minutes
• C. It turns into a powdery residue
• D. It becomes impossible to remove

Answer: (B)

When nitrocellulose paint is exposed to engine oil, it will soften after a few minutes. Nitrocellulose paint is known for its fast drying properties, but it is also sensitive to certain substances, including oils. The chemical composition of nitrocellulose makes it susceptible to the effects of oils, leading to a breakdown of its structure. When engine oil comes into contact with the paint, it disrupts the film's integrity and causes it to lose its adhesion and rigidity, resulting in softening. This characteristic is important for maintenance and repair work on aircraft, as using oil-based products or failing to protect painted surfaces from oil can lead to undesirable effects. Proper handling is essential to prevent damage to the aesthetic and protective qualities of nitrocellulose finishes.
