What is Tesa 7808?
Tesa 7808 is a high-quality deep black acrylic foam tape, specifically engineered for permanent bonding applications that require strong adhesion and environmental resistance. Its viscoelastic acrylic foam core effectively compensates for material movements due to thermal expansion and contraction, offering reliable bonds even under extreme temperature variations. The tape’s deep black color allows for concealed bonding, making it highly suitable for decorative exterior components, especially in automotive and construction sectors.
Composition and Structure
- Base Material: Modified acrylic foam core for high flexibility and bonding strength
- Adhesive Type: Modified acrylic adhesive with strong tack and environmental durability
- Total Thickness: 800µm (0.8mm), providing optimal balance between cushioning and strength
- Color: Deep black, allowing for invisible bonding in dark-colored components
- Elongation at Break: 1400%, enabling excellent adaptability to component movement and stress
- Temperature Resistance:
- Long-term: 120°C
- Short-term: 180°C
- Standard Width: 1260mm (customizable upon request)
- Standard Length: 33m (customizable upon request)
Key Properties
- Strong adhesion: Ensures durable bonding on various materials including metals, plastics, and composites
- High cold shock resistance: Maintains adhesion performance even in extremely cold environments
- Viscoelastic foam core: Absorbs and disperses dynamic and static shear forces, preventing stress accumulation
- Excellent elongation (1400%): Adapts to material movements without failure
- Closed-cell foam structure: Provides sealing and waterproofing, ideal for outdoor use
- UV and moisture resistance: Performs well under harsh environmental exposure
- Good gap-filling capability: 0.8mm thickness allows for effective bonding on uneven surfaces
- Deep black aesthetic: Discreet and visually appealing for dark surfaces
Applications of Tesa 7808
- Automotive Industry:
- Permanent bonding of exterior trims, such as body anti-collision strips, decorative strips, spoilers, antennas, B-pillar trims, nameplates
- Compensation for thermal expansion and contraction, ensuring long-term stable adhesion
- Sealing and waterproofing of exterior parts, suitable for high moisture and weather-exposed areas
- Electronics Industry:
- Bonding and fixation of internal components requiring shock absorption, waterproofing, and impact resistance
- Suitable for consumer electronics, automotive electronics, and rugged devices
- Construction Industry:

Comparison with Other Adhesive Tapes
- Thinner (0.8mm) than some heavier-duty tapes (like Tesa 7815), making it suitable for applications requiring less bulk but high strength
- Higher cold shock and thermal expansion compensation than standard double-sided tapes
- Stronger bonding on difficult surfaces (plastics, metals) compared to typical foam or PE tapes
- More UV and moisture resistant than general-purpose acrylic tapes
- Offers better viscoelastic stress relief compared to rigid adhesive tapes
- More aesthetic for dark surfaces than transparent or white tapes
