4. Configuració i preparació

Proper surface preparation is crucial for optimal performance of the Permatex PermaShield sealant. Follow these steps to ensure a clean and ready surface for application.

Materials necessaris:

• Permatex 85420 PermaShield Fuel Resistant Gasket Dressing & Sealant
• Clean cloths or rags
• Appropriate solvent (e.g., brake cleaner, acetone) for degreasing (ensure compatibility with surfaces)
• Guants de seguretat i protecció ocular

Passos de preparació:

1. Ensure all surfaces to be sealed are clean, dry, and completely free of any paint, dirt, grease, or old gasket material. Use a suitable solvent to thoroughly clean the surfaces if necessary, then allow them to dry completely.
2. Carefully pierce the top of the sealant tube using the back of the cap.

5. Operating and Application Instructions

Follow these instructions for effective application of the Permatex PermaShield sealant.

Procediment de sol·licitud:

1. Apply a thin, even film or bead of the PermaShield product to both mating surfaces that will form the gasket seal.
2. Allow the applied film to dry simply, which permits the solvent to completely evaporate. This step is crucial for the sealant to achieve its optimal tacky state.
3. Once the solvent has evaporated and the sealant is tacky, assemble the components.
4. Tighten the assembly to the manufacturer's specified torque settings.
5. Re-check the torque after approximately 10 minutes to ensure proper seating and sealing.
