- Processing
Processing temperature: 15°C to 25°C
- Preparation:
The surfaces must be clean, dry and free of grease. Metals must normally be pretreated and possibly sanded. Surfaces of glass fiber-reinforced plastics must also be sanded. Resin and hardener must be thoroughly mixed with a stirrer (approx. 400 revs/min) until the mixture shows a uniform color. Prepare tandem cartridge as instructed.
- Bonding:
Apply adhesive evenly with a spatula or a doctor blade to the surfaces and join them. The thickness of the adhesive layer depends on the properties of the materials to be bonded. By different A-components, the pot life and the bond strengths can be varied. When using Körapur 784, the bond can be exposed to light strain after 12 hours. Final bond strength is reached after 24 hours. High temperatures will shorten the curing time, low temperatures will lengthen it.
A-component Pot life Handling time after
Körapur 784/5 5 minutes 1-2 hours Körapur 784/1 1 minute 15 minutes - Cleaning: Körasolv PU
Clean tools immediately after use. Cured adhesive can only be removed mechanically.

Suitable Substrates PVC-U (rigid) Various aluminium alloys Various steel alloys Consistency Various composite materials (e.g. CFRP, GFRP)
Non-sagging Pasty Surface Requirements Dry Clean Free of grease Free of dust Application Method Using side-by-side cartridge with static mixer
Application Equipment Two part mixing and metering system
Product is free of Solvents - Cleaner for Tools Körasolv® PU
- Moisture Sensitivity The adhesive must not be exposed to moisture before and during application. Moisture causes foaming leading to lower mechanical properties.
Safety & Health
- Precautions
When processing Körapur 784 avoid direct skin contact with the uncured adhesive. Wear protective gloves. Hazardous fumes may form when the product is heated or sprayed.
