Super Strong Double Sided Tape
Super strong double sided tape refers to adhesive tapes exhibiting significantly higher bonding strength than standard double sided tapes. These tapes are engineered for demanding applications requiring a robust and durable hold.
Material
The core material varies based on intended use and performance characteristics, but common compositions include:
- Acrylic Foam: Predominantly used in automotive, signage, and construction. Offers excellent long-term durability, resistance to UV light, temperature fluctuations, and solvents. Often features a viscoelastic core.
- Modified Acrylic: Provides strong adhesion to a wide range of surfaces, including plastics, metals, and painted surfaces. Good for general-purpose heavy-duty bonding.
- Rubber-Based: Offers immediate tack and high initial adhesion, suitable for quick bonding applications. Generally less resistant to environmental factors than acrylic-based tapes.
- PET (Polyethylene Terephthalate) Backed: Provides dimensional stability and increased strength, often used with acrylic or rubber adhesives.
- Non-woven Fabric Backed: Offers conformability and can be used with various adhesives, often used for mounting and general assembly.
Purpose
The primary purpose is to provide a permanent or semi-permanent bonding solution without the need for mechanical fasteners (screws, nails, rivets). It is used in applications where:
- Weight-bearing is required.
- Vibration or shock resistance is necessary.
- A clean aesthetic is desired (avoiding visible fasteners).
- Fastening to dissimilar materials is needed.
- Reduced stress on bonded surfaces is important (compared to rigid fasteners).
Function
The function relies on the adhesive properties of the tape, which are determined by:
- Adhesion: The ability of the adhesive to wet the surface and form a bond.
- Cohesion: The internal strength of the adhesive itself, resisting tearing or splitting.
- Tack: The initial stickiness of the tape.
- Shear Strength: The tape’s resistance to forces applied parallel to the bonded surface.
- Tensile Strength: The tape’s resistance to forces applied perpendicular to the bonded surface.
- Viscoelasticity: (Especially in acrylic foam tapes) The ability to absorb stress and distribute loads over time, improving long-term performance.
Usage Scenarios
- Automotive: Mounting exterior trim, badges, and body panels.
- Construction: Bonding panels, insulation, and signage.
- Signage: Securing signs to walls, windows, and other surfaces.
- Electronics: Mounting components and displays.
- General Assembly: Bonding dissimilar materials in various manufacturing processes.
- Home Improvement: Hanging heavy objects, securing mirrors, and mounting shelves.
- DIY Projects: A wide range of applications requiring a strong and permanent bond.
Common Types
- VHB (Very High Bond) Tape: A trademarked acrylic foam tape by 3M, known for its exceptional bonding strength and durability. Widely used in automotive and construction.
- Mounting Tape: General-purpose acrylic or rubber-based tapes for various mounting applications.
- Industrial Grade Double Sided Tape: Heavy-duty tapes designed for demanding industrial applications, often featuring high shear and tensile strength.
- Removable Double Sided Tape (High Strength): While "super strong" usually implies permanence, some formulations offer high strength and removability, though performance is often a trade-off.
- Foam Tape: Offers cushioning and vibration dampening in addition to bonding strength.
- Cloth Tape: Provides conformability and is often used for bundling and general assembly.
