High Adhesion Bonding Tapes
-- Steady & Reliable Manufacturer --
Viscoelastic and Structural Tapes for Permanent, High-Stress Assembly
These tapes are engineered as high-strength, double-sided systems, primarily featuring a thick layer of viscoelastic acrylic foam or a densely cross-linked rubber adhesive applied to a conformable foam or robust film carrier. The formulation is optimized to exhibit exceptionally high initial tack (rapid surface 'grab') and ultimate peel and shear adhesion (typically exceeding $30 \text{ N/25mm}$ peel strength).
The key structural advantage lies in the viscoelastic properties of the foam/adhesive core, which allows the tape to distribute dynamic and static stress loads across the entire bond line. This capability effectively compensates for thermal expansion/contraction differences between dissimilar substrates (e.g., metal to plastic) and significantly dampens vibration and shock. This often allows for the permanent replacement of mechanical fasteners (screws, rivets, liquid adhesives), providing a cleaner aesthetic and faster assembly process.
The thick adhesive structure is highly effective at gap filling, accommodating slight surface irregularities, tolerances, and surface energy differences between various materials. Long-term durability is guaranteed by the high internal strength (cohesion) of the adhesive mass, which resists splitting or internal failure when subjected to sustained static load or cyclical stress in demanding environments like automotive or heavy appliance manufacturing.
Why Choose Us
Key Performance Features and Technical Advantages
- Superior Stress Distribution (Viscoelastic Core): The viscoelastic foam/adhesive core absorbs and redistributes mechanical stress and thermal expansion differentials between dissimilar bonded materials (e.g., metal to plastic), preventing localized high-stress points and premature bond failure.
- High Ultimate Peel and Shear Strength: Engineered to achieve extremely high static and dynamic shear performance (e.g., $>30 \text{ N/25mm}$ peel), allowing the tape to replace mechanical fasteners in many structural, load-bearing, and high-vibration assemblies.
- Vibration and Shock Dampening: The thick, compliant foam structure effectively absorbs dynamic loads, road vibrations, and impact shock, contributing to product longevity and reducing operational noise in appliances and vehicles.
- Excellent Gap Filling Capability: Thicker foam construction compensates for surface irregularities, texture mismatches, and manufacturing tolerances (gaps up to $3 \text{ mm}$), ensuring a continuous bond line and maximum contact area.
- Temperature and UV Resilience (Acrylic): Advanced acrylic adhesive systems maintain their high internal strength (cohesion) and bond strength under prolonged exposure to high heat, cold, and intense UV light, guaranteeing long-term exterior and interior durability.
- Aggressive Initial Tack and Wet-Out: High-tack adhesive quickly flows into microscopic surface pores, ensuring immediate grip upon application, which is crucial for high-speed automated assembly lines and reliable initial handling strength.
Core Features

Frequently Asked Questions
High Adhesion Tape FAQs
- Q: What surface preparation is absolutely required to achieve the strongest ultimate bond strength?
- A: Optimal ultimate bond strength depends on the tape's ability to 'wet out' the substrate completely. Preparation must ensure the surface is clean, dry, and free of contaminants like mold release agents, oils, and dust. For most high-energy surfaces (metals), cleaning with Isopropyl Alcohol (IPA) is sufficient. For Low Surface Energy (LSE) plastics (e.g., PP, PE), the use of a specialized adhesion promoter (primer) is strongly recommended to modify the surface energy and ensure permanent structural grip.
- Q: How long does it take for the high adhesion tape to reach its full ultimate bond strength?
- A: While initial handling strength is immediate (allowing assembly to proceed), the viscoelastic adhesive requires a cross-linking and curing period to achieve its full ultimate static shear and peel strength. This process typically takes 24 hours to 72 hours under standard room temperature conditions ($20^\circ\text{C}$ to $25^\circ\text{C}$). Application at lower temperatures will require a longer cure time.
- Q: What is the tape's ability to handle thermal expansion differences between two bonded materials?
- A: This is a core advantage of our viscoelastic acrylic foam tapes. The foam core acts as a stress-relaxation layer. It absorbs the differential forces generated when two dissimilar materials (e.g., Aluminum and Polycarbonate) expand or contract at different rates due to temperature changes, preventing the adhesive or the substrate itself from failing under concentrated stress.
- Q: Can high adhesion tapes be used in structural applications where the bond is load-bearing?
- A: Yes, when properly specified and applied, these tapes are designed for semi-structural applications, replacing many rivets, spot welds, and screws. They are considered load-bearing, particularly for static and dynamic shear forces in non-critical assemblies (like appliance panels and automotive trim). We provide detailed static and dynamic shear test reports to help engineers determine the tape's suitability for specific load requirements.
