What is Tesa 58451?
Tesa 58451 is a black, double-sided reactive adhesive film designed for structural bonding applications. It is non-sticky at room temperature and becomes active only when heat and pressure are applied during the assembly process. The adhesive composition offers reliable conductivity and long-term stability, making it ideal for high-performance bonding in confined spaces and thin design structures.
Composition and Structure
- Adhesive system: Phenolic resin and nitrile rubber (heat-activated)
- Structure: Double-sided adhesive film without a carrier
- Liner: 50 μm PET liner
- Color: Black or grey-black
- Thickness: Available in various specifications based on application needs
- Adhesion state: Non-tacky at room temperature; activated under heat and pressure
Key Properties
- Excellent electrical conductivity in xyz directions
- High bonding strength in tight, narrow bonding areas
- Excellent thermal stability and resistance to rebound under heat
- Strong chemical resistance for harsh environments
- Low adhesive bleed for clean bonding surfaces
- Outstanding durability and anti-aging performance
Applications of Tesa 58451
- Metal to plastic bonding in electronic assemblies such as stainless steel to ABS, PC, or PMMA
- Structural fixation of internal electronic components, including keys, display windows, and module housings
- Bonding of decorative metal parts in appliances and automotive interiors
- Panel and part fixation requiring high temperature resistance
- Any application that requires precise, reliable, and conductive bonding
Features & Benefits of Tesa 58451
- Heat activation enables clean, precise application
- Maintains conductivity and adhesion in high-temperature environments
- Resists solvents, moisture, and aging for long-term reliability
- Suitable for bonding dissimilar materials like metal and plastic
- Ideal for compact, high-spec electronic and structural designs
- Ensures strong mechanical and conductive performance
Comparison with Other Adhesive Tapes
- Unlike pressure-sensitive tapes, Tesa 58451 is heat-activated for more secure structural bonding
- Provides stronger resistance to temperature and chemical stress than conventional conductive tapes
- More suitable for permanent bonding between metal and plastic than standard acrylic-based tapes
- Combines conductivity with clean application and long-term stability
