3. Producte acabatview

The Scotch Rubber Mastic Tape 2228 features an ethylene-propylene rubber (EPR) backing coated with a temperature-stable mastic adhesive. This combination provides excellent electrical insulation and moisture sealing properties.

Key Characteristics:

• Self-Fusing: The tape fuses to itself, creating a seamless, void-free insulation and seal.
• Highly Conformable: Its thick construction (65 mil) allows for quick build-up and padding over irregular connections, ensuring a tight seal.
• Aïllament elèctric: Provides primary electrical insulation for cable and wire connections and vibration padding for motor leads rated up to 1000 V.
• Moisture Sealing: Offers superior adhesion and sealing characteristics with copper, aluminum, and various power cable jacket materials.
• Temperature Stable: Designed for applications up to 130 ℃ (266 ℉).
• Resistència ambiental: Resistant to moisture and ultraviolet (UV) exposure, suitable for both indoor and weather-exposed outdoor environments.

4. Configuració i preparació

Proper preparation of the surface and the tape is crucial for optimal performance.

4.1 Eines i materials necessaris:

• 3M Scotch Rubber Mastic Tape 2228
• Clean cloth or solvent for surface cleaning (if necessary)
• Utility knife or scissors (for cutting tape)
• Equips de protecció individual (EPI)

4.2 Preparació de la superfície:

1. Ensure the surface where the tape will be applied is clean, dry, and free from oil, grease, dust, or other contaminants.
2. If necessary, clean the surface with an appropriate solvent and allow it to dry completely.
3. The ambient temperature should be within the recommended application range for best results.

5. Instruccions d'ús (aplicació)

Follow these steps for effective application of the 3M Scotch Rubber Mastic Tape 2228.

1. Desenrotllar i tallar: Unroll a sufficient length of tape from the roll. Cut the desired length using a utility knife or scissors.
2. Remove Liner: Peel back the protective liner from the mastic side of the tape. Work with short sections at a time to prevent the mastic from sticking to itself or other surfaces prematurely.
3. Apply with Tension: Begin applying the tape to the prepared surface. Stretch the tape to approximately 75% of its original width during application. This stretching helps the tape conform and self-fuse effectively.
4. Superposició: For optimal insulation and sealing, overlap each successive wrap by at least 50% of the tape's width. This creates a continuous, void-free layer.
5. Conform to Irregularities: Press the tape firmly into place, especially around irregular shapes or connections, to ensure full contact and eliminate air voids. The conformable nature of the tape allows it to mold around complex geometries.
6. Acabar l'aplicació: Once the desired area is covered, cut the tape and press the end firmly onto the previous layer. The tape will begin to self-fuse, forming a durable, moisture-resistant seal.

6. Manteniment

The 3M Scotch Rubber Mastic Tape 2228 is designed for long-lasting performance with minimal maintenance once applied correctly.

• Emmagatzematge: Store unused tape rolls in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures, to maintain adhesive integrity.
• Inspecció: Periodically inspect applied tape for any signs of damage, degradation, or loss of adhesion, especially in outdoor or harsh environments.
• Reparació/substitució: If damage is observed, remove the affected section and reapply new tape following the operating instructions to ensure continued protection.

7. Solució De Problemes

Most issues with 3M Scotch Rubber Mastic Tape 2228 can be resolved by ensuring proper application techniques.

• Mala adherència:
  • Assegureu-vos que la superfície estigui neta i seca abans de l'aplicació.
  • Verify sufficient tension was applied during wrapping to promote self-fusing.
  • Check if the tape was stored correctly; extreme temperatures can affect adhesive performance.
• Incomplete Seal/Voids:
  • Ensure each wrap overlapped the previous one by at least 50%.
  • Apply firm pressure to conform the tape to all contours and eliminate air pockets.
  • Stretch the tape adequately during application.
• Tape Degradation:
  • While resistant, prolonged exposure to harsh chemicals or extreme conditions beyond specifications may affect longevity.
  • Ensure the tape is suitable for the specific environmental conditions of the application.
