Dry film lubricant is applied using a spray gun or air brush in multiple thin, uniform coats.
Step-by-step Application Process
The application of dry film lubricant involves a specific process to ensure optimal performance and adhesion:
- Preparation: Ensure the surface is clean and free from any contaminants before application. This might include degreasing or other surface prep techniques.
- Spray Application:
- Use a spray gun or air brush to apply the lubricant.
- Apply several thin, uniform coats rather than a single thick coat. This allows for better drying and adhesion.
- Drying Between Coats:
- Allow each coat to dry completely before applying the next.
- Air Drying:
- After the final coat, allow all parts to air dry at room temperature for at least 30 minutes before the curing cycle.
- Curing:
- Once air-dried, the parts may undergo a curing process according to the lubricant's specifications. (Note: This step isn't part of the application process itself, but a critical step in the process).
Why Multiple Thin Coats?
Applying multiple thin coats is crucial for several reasons:
- Even Coverage: It helps ensure uniform coverage over the entire surface.
- Proper Adhesion: Thin layers adhere better to the substrate, reducing the risk of peeling or flaking.
- Drying Time: Thin coats dry quicker, reducing total application time and preventing runs or drips.
- Performance: Uniform coating enhances the performance and lifespan of the lubricant.
Equipment
The most common tools for applying dry film lubricant are:
- Spray Gun: Ideal for larger surfaces. Provides a controlled and even spray pattern.
- Air Brush: Suitable for smaller, more intricate parts, offering finer control.
In summary, applying dry film lubricant correctly is important to achieve its intended performance. Utilizing a spray gun or air brush to apply multiple thin layers, allowing each to dry, and ensuring adequate air drying time before curing, ensures a good result.
