DuploCOLL® 59153.4 for speed, safety & sustainability in door profile bonding
In fire doors, the adhesive interface plays a decisive role - not only in long-term seal reliability, but also in production efficiency and system qualification. OEMs integrating intumescent profiles require bonding solutions that combine reliable adhesion behavior, clean process integration, and stable mechanical properties over time.
With DuploCOLL® 59153.4, Lohmann sets a new benchmark in adhesive technology for intumescent door strips and supports precisely these requirements. Manufacturers of door sealing profiles operate under tight tolerances and demanding throughput expectations. Bonding performance must be predictable, repeatable, and compatible with automated handling.
DuploCOLL® 59153.4 delivers:
Fast handling strength development
Achieves strong bond performance in approximately 10 minutes — enabling shortened dwell times and improved takt speeds.
Secure initial tack
Reliable initial adhesion supports precise positioning
Polyester carrier stability
Dimensional stability of the carrier facilitates:
- Precise die-cutting
- Consistent profile lamination
- Controlled application in extrusion & post-processing
Optional solvent-free adhesive system
A sustainability-optimized variant is available, supporting environmentally conscious system platforms without compromising functional performance.
Versatility in fire-door system architectures
Supports both new construction and retrofit sealing concepts, providing manufacturing flexibility across model ranges and product tiers.
Why Adhesive Performance Matters in System Integrity
In an intumescent sealing system, the adhesive must maintain its position and integrity to ensure the profile remains effective throughout the door’s lifetime - including exposure to fluctuating temperatures, mechanical stress during installation, and long-term material aging.
Consistent bond behavior contributes directly to assembly confidence and fire protection functionality.
Supporting OEMs in System Engineering
Lohmann offers:
- Technical consultation for material compatibility
- Processing recommendations for line integration
- Sample support and prototype evaluation
- Engineering collaboration for system qualification
Because adhesive selection is not a commodity decision! It is a performance component in the overall fire-door system.
