Yes, Fluid Film can cause smoking after being applied, particularly when applied to hot surfaces like exhaust systems or engine components. The smoking is due to the product’s petroleum-based solvents and lanolin oil vaporizing at elevated temperatures. However, this smoking is generally considered temporary and should dissipate as the volatile components burn off.
Understanding the Chemistry of Fluid Film
Fluid Film is a popular rust inhibitor and lubricant known for its creeping abilities and long-lasting protection. Its unique formulation, largely based on refined lanolin extracted from sheep’s wool, provides a persistent coating that resists water and corrosive elements. However, along with lanolin, Fluid Film also contains petroleum-based solvents. These solvents are crucial for the product’s initial application, allowing it to penetrate tight spaces and evenly coat surfaces. These are also the primary culprits behind the smoking phenomenon.
When Fluid Film is applied to a surface that heats up, particularly above the boiling points of its solvent components, these solvents begin to vaporize. This vaporization process creates visible smoke, which is essentially the airborne form of these volatile organic compounds (VOCs). The intensity and duration of the smoking depend on several factors, including the amount of Fluid Film applied, the temperature of the surface, and the ventilation of the area.
The Smoking Risk: A Detailed Examination
While the smoking itself is often harmless and temporary, understanding the potential risks is vital.
Flash Point Considerations
Fluid Film has a flash point – the lowest temperature at which its vapors can ignite in air. While relatively high compared to some other petroleum-based products, the flash point indicates that Fluid Film vapors are flammable. Therefore, applying Fluid Film near open flames or ignition sources is strictly discouraged.
Respiratory Irritation
The vapors released during the smoking process can also cause respiratory irritation in some individuals. The level of irritation varies depending on individual sensitivity and the concentration of vapors. Adequate ventilation is crucial when applying Fluid Film, especially in enclosed spaces, to minimize the risk of respiratory discomfort. Using a respirator or mask is recommended if you are sensitive to fumes.
Potential Damage to Surfaces
In rare cases, excessive application of Fluid Film onto extremely hot surfaces might lead to a localized build-up of residue that could potentially cause discoloration or a slight change in surface characteristics. However, this is less common and primarily occurs with improper application techniques.
Application Guidelines to Minimize Smoking
To minimize the risk of smoking and other potential issues, follow these application guidelines:
- Apply Sparingly: Avoid excessive application. A thin, even coat is sufficient for effective rust protection.
- Avoid Hot Surfaces: Whenever possible, avoid applying Fluid Film directly to surfaces that are already hot, such as exhaust manifolds or catalytic converters. Allow these components to cool down before application.
- Ventilation is Key: Ensure adequate ventilation during and after application, particularly in enclosed areas. Open windows and doors or use fans to circulate air.
- Test in an Inconspicuous Area: Before applying Fluid Film to the entire surface, test it in a small, hidden area to ensure it doesn’t react negatively with the material.
- Follow Manufacturer Instructions: Always refer to the manufacturer’s instructions and safety data sheet (SDS) for specific guidance on application, safety precautions, and handling procedures.
Frequently Asked Questions (FAQs)
1. How long does the smoking typically last after applying Fluid Film?
The duration of the smoking varies, but it usually lasts from a few minutes to up to an hour, depending on the surface temperature and ventilation. In most cases, the smoking will cease once the volatile solvents have evaporated.
2. Is the smoke from Fluid Film harmful to breathe?
The smoke can cause respiratory irritation in some individuals. It’s recommended to avoid prolonged exposure and ensure adequate ventilation during and after application.
3. Can I use Fluid Film on my car’s exhaust system?
While some people use Fluid Film on their exhaust systems for rust protection, it’s generally not recommended. The high temperatures can cause significant smoking and potential fire hazard. If used, apply very sparingly to a cool exhaust system and monitor closely.
4. What should I do if Fluid Film catches fire?
If Fluid Film catches fire, immediately use a Class B fire extinguisher designed for flammable liquids. Avoid using water, as it can spread the fire. Call emergency services if the fire is uncontrollable.
5. Does the color of Fluid Film affect the likelihood of smoking?
No, the color of Fluid Film (e.g., NAS, Black) does not significantly affect the likelihood or intensity of smoking. The smoking is primarily related to the vaporization of the petroleum-based solvents present in all Fluid Film formulations.
6. Can I dilute Fluid Film to reduce the smoking?
While technically you could dilute Fluid Film with a compatible solvent, it’s not recommended. Diluting the product can compromise its rust-inhibiting properties and overall effectiveness. It’s better to apply it sparingly and ensure proper ventilation.
7. Will the smoking eventually damage my vehicle’s paint or other surfaces?
In most cases, the smoking will not damage vehicle paint or other surfaces. However, excessive application and prolonged exposure to hot surfaces could potentially lead to discoloration or residue build-up. It’s always best to test in an inconspicuous area first.
8. Are there any alternatives to Fluid Film that don’t smoke as much?
Yes, there are alternative rust inhibitors and lubricants that may produce less smoke. Consider products formulated with synthetic oils or those with higher flash points. However, ensure these alternatives are compatible with the intended application and provide the necessary level of corrosion protection.
9. Does colder weather reduce the likelihood of smoking?
Yes, colder weather generally reduces the likelihood and intensity of smoking because the surface temperatures are lower, resulting in less solvent vaporization.
10. Is Fluid Film food-grade? Can I use it on food processing equipment?
No, Fluid Film is not food-grade and should not be used on food processing equipment or surfaces that come into contact with food. Use only lubricants specifically designed and approved for food-grade applications.
11. How should I properly dispose of used Fluid Film cans or rags?
Dispose of used Fluid Film cans and rags in accordance with local regulations for hazardous waste disposal. Contact your local waste management authority for specific instructions. Do not incinerate or puncture cans.
12. What are the long-term effects of using Fluid Film on rubber or plastic components?
While Fluid Film is generally considered safe for use on most rubber and plastic components, prolonged and repeated exposure could potentially cause softening or swelling in some materials. It’s always best to test a small, inconspicuous area first to ensure compatibility. Avoid direct contact with sensitive or critical rubber components.
