Polyurethane adhesive DuploTEC® SBF

for metalsingle-componentindustrial

Overview
Reactive bonding films and tapes combine pressure-sensitive application ease with the performance of reactive adhesives to deliver efficient, reliable structural and semi-structural bonds. These pre-applicable, dimensionally precise products reduce process complexity and enable faster, cleaner assembly workflows.

Innovative Reactive Films and Tapes — Three Advanced Technologies
Three complementary technologies cover a wide range of production requirements while enabling pre-application and controlled activation: UV-activatable tape (UV-LUX®), thermosetting polyurethane film (DuploTEC® SBF Polyurethane) and thermosetting epoxy tape (DuploTEC® SBF Epoxy). Each technology offers specific process and performance properties to match application needs.

UV-LUX® — UV-Activatable Tape
UV-LUX® is a UV-light activatable adhesive tape designed for rapid activation and safe processing even in dark environments. An optional color-change visual indicator supports process control and repeatability.

• UV activation (365 nm) within seconds.
• Optional color change at activation for visual process control.
• Up to 10 minutes open time.
• Immediate handling strength after activation; full strength reached in ~24 hours.

DuploTEC® SBF Polyurethane — Thermosetting Polyurethane Film
DuploTEC® SBF Polyurethane is a solvent-free, dry adhesive film offering rapid crosslinking at relatively low temperatures, making it suitable for short cycle-time production with durable, flexible bonds.

• Thermosetting polyurethane adhesive system; solvent-free dry film.
• Latent reactive behavior with semi-structural bonding characteristics.
• Pre-applicable at 50–55°C; stable in storage up to 3 months after pre-application.
• Activation typically between 70–160°C; activation within seconds possible.
• Remains elastic and flexible after curing; suitable for short cycle times.

DuploTEC® SBF Epoxy — Thermosetting Epoxy Tape
DuploTEC® SBF Epoxy combines pressure-sensitive handling with structural bonding performance after curing. It is formulated for high strength, durability and resistance to aging and chemicals.

• Epoxy-based thermosetting tape with initial tack for easy positioning.
• Structural bonding performance; available in multiple formulations and thicknesses.
• Curing starts from ~130°C; curing time depends on temperature and formulation.
• Adaptable to specific process conditions; recommended minimum pressure: 1 N/cm².

Your benefits

• PSA-like applicability with initial tack for simplified handling and positioning.
• Safe, controlled processes via color change and defined open time (UV-LUX®).
• Semi- to structural bonding behavior with high final strength.
• Choice of low curing temperatures (polyurethane) or high heat/chemical resistance (epoxy) depending on chemistry.
• Immediate handling strength after activation enabling efficient production flows.
