Genuine tesa 4962 Double-Sided Non-Woven Tape | Heavy-Mass High-Tack Acrylic Tape - STK
STK supplies Genuine tesa 4962 Double-Sided Tape, a premium industrial-grade 160μm (6.3-mil) heavy-mass non-woven tissue tape engineered specifically for critical high-tack heavy-mass substrate lamination and textured surface bonding. Featuring an exceptionally thick, high-tack modified acrylic adhesive system deeply impregnated into a highly conformable non-woven carrier, tesa 4962 bridges the interface on difficult, uneven, and low surface energy (LSE) materials where standard thin tapes experience contact starvation.
The defining technological edge of tesa 4962 is its heavy coating weight wet-out capability. By deploying an increased mass of aggressive acrylic polymer per square meter, the adhesive acts as a microscopic fluid cushion under pressure. It flows smoothly into the micro-cavities of porous timbers, fibrous acoustic felts, and textured interior trim components, establishing an unyielding mechanical interlock that transforms unreliable heterogeneous interfaces into permanent structural joints.
Features
For automotive trim assembly supervisors, high-volume foam fabricators, and industrial leather laminating specialists, tesa 4962 provides a zero-failure bond line that completely eliminates post-assembly lifting:
• Heavy Coating Weight Wet-Out:
Packed with an aggressive, thick acrylic layer designed to deeply wet-out and fill highly porous, fibrous, or textured profiles. It maximizes true microscopic surface contact area instantly upon application.
• Fierce Initial Edge-Grab:
Establishes an immediate, high-tack mechanical bond upon touch. It completely eliminates edge-lifting and spring-back delamination on highly warped or stressed injection molded plastics.
• Multi-Material Interior Bonding:
Flawlessly bridges heterogeneous bonds between low-density open-cell foams, acoustic felt fabrics, heavy split leathers, and rigid ABS or polypropylene (PP) dashboards.
• Excellent Temperature & Aging Resistance:
The specialized cross-linked acrylic formulation resists degradation from environmental heat cycles up to short-term peaks of +200°C (+392°F), maintaining high shear resistance inside enclosed, sun-baked vehicle cabins.

Applications
Automotive Interior Trim & Headlining: Mounting acoustic insulating felts, overhead textile liners, leather door-panel inserts, and complex plastic brackets inside passenger car and heavy truck cabins.
Heavy-Duty Foam & Gasket Fabrication: Permanent lamination of open-cell polyurethane (PU) foams, polyethylene (PE) foam sheets, and EPDM rubber sheets onto metal enclosures or plastic device housings.
Premium Leather Goods & Fabric Composite: Pre-positioning and permanent structural bonding of heavy split leathers, synthetic textiles, and decorative fabrics during high-end furniture and luggage manufacturing.
Point-of-Purchase (POP) Display Assemblies: Securing heavy cardboard corrugated structures, molded plastic display parts, and textured wooden promotional frames where instant holding power is required.
STK Custom Supply Power: Precision Custom Slitting & High-Volume Log Distribution
Processing a heavy-mass non-woven tape requires advanced converting equipment to prevent adhesive squeeze-out and ensure perfectly crisp roll edges. STK directly optimizes your manufacturing pipeline:
Micro-Precision Roll Slitting
Because tesa 4962 features a high-mass adhesive coat, poor slitting can cause severe edge-oozing and roll blocking. STK utilizes specialized chilled-blade lathe slitters to convert master logs into exact narrow or wide widths (e.g., 12mm, 19mm, 25mm, 50mm) with flawlessly straight roll faces.
Custom Die-Cut Component Gaskets
tilizing our advanced flatbed die-cutting presses, STK converts tesa 4962 into highly accurate pre-cut foam backings, multi-cavity perimeter frames, and mounting dots delivered on clean release liners with extended pull-tabs to speed up manual line workers.
