5. Instruccions d'ús

5.1. Preparació de la superfície

For optimal adhesion, ensure the surface is clean, dry, and free from dust, grease, oil, or other contaminants. A clean surface will maximize the tape's adhesive properties and ensure a long-lasting bond.

5.2. Aplicació

1. Unroll the desired length of tape.
2. Carefully peel back the release liner (backing paper) from one end of the tape.
3. Align the tape with the seam or area to be sealed.
4. Press the exposed adhesive side firmly onto the surface, gradually peeling back the release liner as you apply the tape.
5. Smooth out any air bubbles or wrinkles using a squeegee or a clean cloth to ensure full contact with the surface.
6. For best results, apply firm, even pressure across the entire length of the tape.

6. Manteniment i emmagatzematge

To maintain the quality and performance of 3M Aluminum Foil Tape 3381:

• Guardeu la cinta en el seu embalatge original en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
• Avoid exposing the adhesive side to dust or contaminants before application.
• Ensure the tape roll is kept clean to prevent debris from sticking to the edges.

7. Solució De Problemes

7.1. Poor Adhesion

If the tape is not adhering properly, consider the following:

• Neteja de la superfície: Re-clean the surface thoroughly to remove any dirt, dust, or oils.
• Temperatura: Ensure the application temperature is within the recommended range (-30°F to 250°F). Extreme cold or heat during application can affect adhesion.
• Pressió: Apply sufficient, firm pressure during application to ensure maximum contact between the adhesive and the surface.

7.2. Tape Tearing During Application

While the tape is designed to be conformable, excessive force or improper handling can cause tearing:

• Manipulació suau: Handle the tape carefully, especially when peeling the release liner.
• Aplicació suau: Apply the tape smoothly and evenly, avoiding sharp tugs or angles.
