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 applicationsStress 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.- Preparation
For some substrates the use of mechanical pretreatment and/or cleaner or primer is necessary to achieve good adhesion.
- Processing
Low temperatures can cause a temporary increase in viscosity resulting in reduced extrusion and slower curing rates.
- Cleaning Instructions
Clean tools immediately after use. Once cured, the material can only be removed mechanically. Appropriate cleaners are listed in the product properties.
- 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.
