Preparation
- For some substrates the use of mechanical pretreatment and/or cleaner or primer is necessary to achieve good adhesion. Refer to the product properties section of this data sheet for special surface requirements and suitable adhesion promoters.
Processing
- Refer to the technical data table regarding processing parameters. 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.

- Resistance against UV Radiation Not suitable for glass bonding with permanent UV radiation to the bonding area. Please ask your local sales office for products suitable for such applications.
- 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. Please ask your local sales office for products suitable for such applications.
- Avoid Contact with Isocyanate Reactive Substances Avoid direct contact with isocyanate reactive substances, especially alcohol such as spirit, dilutions, cleaning compounds and reaction or curing products of silane-modified polymers or silicones until the adhesive has attained full cure. This will prevent the adhesive from curing properly.
