Application & tips
Prepare bonding surfaces clean, free of grease, dry and sound: clean non-porous surfaces with OTTO Cleaner T, free porous ones mechanically of loose parts. Insert the cartridge into a 2K gun for side-by-side cartridges, squeeze out until both components emerge, fit the static mixer and join the parts within the processing time. Application at +5 to +35 °C, with compressed-air guns maximum 5 bar; trial bonding recommended. Resin and hardener have a sensitising effect: disposable nitrile gloves, safety goggles, avoid skin contact; mix only as much as can be processed within the pot life. Contains isocyanates: ensure good ventilation; cured adhesive can only be removed mechanically. Since 24.08.2023, professional users need training in accordance with REACH Annex XVII No. 74. Clean tools before curing with OTTO Cleaner MP. Store dry at +15 to +25 °C, shelf life unopened 12 months.
