Körasolv GL Körasolv PU Hints
Resistance against UV radiation Not suitable for glass bonding with permanent UV radiation to the bonding area.
Stress cracking Preliminary tests must be carried out on plastics with a tendency to stress cracking. (PMMA, ABS, PC or PS)
Compatibility with polystyrene foams Not suitable for bonding polystyrene foams.
Avoid contact with isocyanate reactive substances Avoid direct contact with isocyanate reactive substances, especially alcohol such as spirit, dilutions, cleaning compounds and fission products of silane-modified polymers or silicones until the adhesive has attained full cure. This will prevent the adhesive from curing properly.
- Low temperatures can cause a temporary increase in viscosity resulting in reduced extrusion and slower curing rates.
- Cleaning: Clean tools immediately after use. Once cured, the material can only be removed mechanically. Appropriate cleaners are listed in the product properties table.
- Dimensioning: The required thickness of the adhesive layer depends on the expected maximum strength and joint movement. We recommend a minimum layer thickness of 2 mm.
