Applications & Uses
- Markets
- Substrates
Crestafix F26R is suitable for use on GRP laminate, but can also be used on timber and plasterboard. However, it is recommended that trials are carried out to ensure that adequate bond strengths are obtained.
- Recommended Applications
- Crestafix F26R is supplied pre-accelerated, requiring only the addition of catalyst to start the curing reaction. The recommended catalyst is Butanox M50, which should be added at 1% v/w into the bonding paste.
- The catalyst should be thoroughly incorporated into the material with a low shear mechanical stirrer where possible, taking care to keep air entrapment to a minimum. Alternatively the bonding paste can be applied with a dispensing unit. The use of additional pigments or fillers is not recommended as they can affect the performance of the adhesive.
- Coverage
As a rough guide, 4.0Kg (9 lbs) of bonding paste will cover one square meter to a depth of approximately 3mm (0.12 inch).
