tesa® ACXplus 74712 Seal Line

The tesa® ACXplus 74712 Seal Line is a deep black acrylic foam tape specifically developed for the permanent mounting of seals, primarily on automotive clearcoats. Its unique composition allows for primerless bonding to low surface energy (LSE) materials, streamlining the application process and enhancing efficiency.

Key Features:

  • Primerless Bonding: Eliminates the need for adhesion promoters on typical PP, PP/EPDM, TPV, or TPE seals, reducing preparation time and improving operational safety.

  • LSE Material Compatibility: Specially formulated adhesives ensure strong adhesion to LSE substrates, providing reliable bonds without primers.

  • Heat-Activatable Adhesive: The non-liner side features a heat-activatable adhesive that bonds securely to door seals upon activation by hot air or near-infrared, enhancing application speed.

  • Viscoelastic Acrylic Foam Core: Offers excellent stress dissipation, accommodating different thermal expansions between bonded parts, and maintaining bond integrity under dynamic and static loads.

  • Temperature Resistance: Maintains performance across a wide temperature range (-40°C to 90°C), suitable for various automotive environments.

  • High Humidity and UV Resistance: Ensures durability and longevity, even under harsh environmental conditions.

Applications:

  • Door Seals: Permanent mounting on automotive clearcoats without the need for primers, simplifying installation and reducing process steps.

  • Window Seals: Secure attachment providing watertight and airtight solutions, enhancing vehicle integrity.

  • Sunroof Seals: Reliable bonding for seals exposed to temperature variations and movements, ensuring consistent performance.

  • Waterbox Seals: Durable sealing solutions for components exposed to moisture, preventing water penetration.
