What is Tesa 7043?
Tesa 7043 is a high-performance double-sided acrylic foam tape designed for versatile bonding applications, especially where impact absorption, high adhesion, and thermal expansion tolerance are required. With a total thickness of 640μm and available in gray and white, Tesa 7043 delivers bubble-free bonding with strong viscoelastic properties that fill gaps and compensate for material movement. It is ideal for applications that require durable, stress-resistant, and aesthetically invisible bonds.
Composition and Structure
- Base Material: Acrylic foam core with viscoelastic properties for stress absorption and gap filling
- Adhesive Type: Pure acrylic adhesive, offering strong, durable, and temperature-resistant adhesion
- Total Thickness: 640μm (0.64mm), providing medium cushioning and adaptability for uneven surfaces
- Color: Available in gray and white, suitable for applications with specific color requirements
- Elongation at Break: 710%, allowing adaptation to material expansion, contraction, and deformation without tape failure
- Temperature Resistance:
- Short-term: Up to 200°C, tolerating temporary exposure to high temperatures
- Long-term: Up to 110°C, ensuring stable performance in continuous high-temperature environments
- Adhesion Strength: Excellent bonding strength, including on “difficult-to-bond” surfaces like powder-coated metals and plastics
- Appearance: Enables bubble-free bonding, forming invisible bonds for decorative applications
Key Properties
- Medium thickness (640μm): Provides cushioning, gap-filling, and shock-absorbing properties
- High adhesion to difficult surfaces: Effectively bonds powder-coated metals, plastics, and glass
- Excellent dynamic stress absorption: Reduces stress concentration and enhances bond durability
- Viscoelastic core: Adapts to thermal expansion/contraction, preventing bond failure over time
- Bubble-free application: Smooth and even bonding without trapped air
- High elongation at break (710%): Adapts to material deformation and movement
- Strong temperature resistance:
- Short-term: up to 200°C for temporary high-heat exposure
- Long-term: up to 110°C for sustained use in elevated temperatures
- Durable and weather-resistant: Maintains bond strength in challenging environments
- Aesthetic (gray/white): Suitable for visible bonding applications requiring a clean appearance
Applications of Tesa 7043
- Decorative Parts Bonding:
- Fixation of refrigerator glass door panels, dishwasher cover decorations, and window pane trims
- Attaching decorative strips, panels, and moldings in appliances and furniture
- Glass Bonding:
- Secure bonding between glass-to-glass and glass-to-metal for applications like partition walls, glass doors, and architectural panels
- Rib Fixing and Structural Reinforcement:
- Fixing ribs and support elements in appliances such as stainless steel range hoods and flues, creating invisible structural bonds
- Bonding Powder-Coated and Plastic Surfaces:
- Reliable adhesion to powder-coated metals and plastics, often challenging for conventional adhesives
