C-Pure PB 20 is a two-part polyurethane structural adhesive engineered for bonding metal panels and mixed materials, featuring a 20-minute working time and 12-hour paint-ready cure. It delivers Shore D 80 hardness, 40,000 mPa·s mixed viscosity, 1.10 relative density, and 15% elongation for high-strength, impact-resistant bonding across steel, aluminum, wood, composites, and concrete. Its durable formulation supports structural applications requiring reliable adhesion and controlled application performance.
Instructions
Prepare and clean all bonding surfaces to remove contaminants.
Dispense and mix both components using a compatible system.
Apply adhesive evenly and position parts within 20 minutes.
Allow the adhesive to cure fully before finishing.
Paint or apply full load after 12 hours.
Applications
Automotive panel bonding including quarter panels, roofs, and door skins
Truck and utility vehicle body assembly
Industrial metal fabrication
Composite-to-metal structural bonding
Construction bonding for wood, concrete, and mixed materials
Good structural adhesive for metal panels when welding is not the best option. It spreads consistently, does not sag much, and cures into a solid bond. We like it for repair work, but full cure time needs to be planned into the job.

We use C-Pure PB 20 for automotive metal panel bonding and small body shop repair jobs. The 20 minute working time gives enough room to position panels properly, and the adhesive stays in place well on vertical areas!
