In general lamination and bonding applications, tapes must not only provide reliable long-term adhesion but also possess excellent processing suitability and environmental adaptability. TESA 68599 is a double-sided transparent tape with a thickness of 300µm, combining high-performance PET backing with modified acrylic adhesive. It is suitable for a variety of materials and complex working conditions, making it the ideal choice for industrial assembly and lamination.
I. Core Product Positioning
TESA 68599 is a high-thickness, universal double-sided tape designed for bonding and lamination processes requiring strong adhesion + excellent workability + environmental resistance. It is suitable for:
✔ Secure bonding on uneven or rough surfaces
✔ Fixation of medium-thick decorative parts, labels, and thin sheets
✔ Intermediate bonding in laminated structures
✔ Long-term adhesion in harsh environments (high temperature, humidity, etc.)

III. Three Key Advantages
- High Adhesion, Multi-Material Compatibility
TESA 68599 uses a modified acrylic adhesive, delivering excellent adhesion to plastics, metals, glass, coated panels, and more. It maintains stable bonding even on rough or slightly uneven surfaces. - Superior Processing Performance
Equipped with a specialized glassine paper release liner, it facilitates die-cutting, waste removal, and automated application, making it ideal for automated assembly, label lamination, and precision die-cutting. - Strong Environmental Resistance
The tape offers outstanding resistance to high temperatures (200°C), humidity, and aging, ensuring reliable adhesion and structural stability even under demanding long-term conditions.
IV. Typical Applications
- Label & Signage Bonding: Secure attachment of nameplates, product labels, acrylic signs, etc.
- Structural Lamination: Intermediate bonding for thin materials (e.g., decorative layers, conductive films).
- Electronic Component Bonding: Mounting of sensors, decorative frames, functional films.
- Industrial Part Fixation: Assembly of plastic components, metal sheets, and composite materials.
- Advertising & Decoration: Quick mounting of indoor/outdoor display panels.
V. Technical Q&A
❓ Q: Can TESA 68599 be used on irregular or slightly rough surfaces?
→ Yes. Its 300µm thickness and high adhesion make it particularly suitable for textured surfaces or applications with minor gaps.
❓ Q: Is waste removal/die-cutting easy during processing?
→ Yes. The glassine paper release liner ensures smooth operation in automated processing, improving yield rates.
❓ Q: Is the heat resistance sufficient for hot-pressing applications?
→ Yes. It can withstand short-term exposure to temperatures up to 200°C, making it suitable for heat-assisted bonding or short-term high-temperature processes.
