What is Tesa 6703?
Tesa 6703 is a high-performance double-sided acrylic foam tape, featuring a gray viscoelastic acrylic foam core that acts simultaneously as adhesive and backing material. Its high thickness of 1100µm offers superior cushioning, filling, and stress distribution, while the acrylic adhesive ensures strong adhesion, temperature resistance, and environmental durability. Tesa 6703 is engineered to securely bond a variety of materials, including metals, plastics, and composites, even under high temperature conditions or in environments that demand strong mechanical stress resistance.
Composition and Structure
- Base Material: Acrylic foam, providing elasticity, cushioning, and stress absorption
- Adhesive Type: Acrylic adhesive for high initial tack and long-term bonding strength
- Total Thickness: 1100µm (1.1mm), offering enhanced gap-filling and cushioning
- Color: Gray, allowing discreet and aesthetic bonding, especially on metal and neutral-tone surfaces
- Temperature Resistance:
- Long-term: Up to 80°C, maintaining stable adhesion in everyday environments
- Short-term: Up to 120°C, tolerating temporary high temperature spikes
- Adhesion Strength: High viscosity for strong and durable bonding on a variety of surfaces including metals, plastics, and composites
Key Properties
- High bonding strength: Provides durable adhesion for heavy and critical components
- Thick acrylic foam (1.1mm): Offers excellent cushioning, filling, and impact absorption
- Good temperature resistance: Maintains bonding strength in environments up to 80°C (long-term) and 120°C (short-term)
- Viscoelastic foam structure: Absorbs and redistributes shear and tensile forces for long-lasting bonds
- Strong shear resistance: Prevents bonded parts from sliding or detaching under mechanical stress
- Aesthetic gray color: Blends well with metallic and neutral-colored materials for hidden bonding
- Flexible and conformable: Adapts to uneven or irregular surfaces
Applications of Tesa 6703
