Casttec 47

Casttec 47 is a pale amber, extended open time precast adhesive designed for environments where the ambient working temperature is high. This means it can be applied, allowed to set and then be cleanly removed at temperatures close to 40°C.

Able to bond wood, plastic, metal, and foam, Casttec 47 can be applied over a light oil, removing the need to clean surfaces before application.

Casttec 47 replaces the need for welding or bolting inserts to precast forms, providing a less destructive, cost-saving alternative for precast concrete manufacturers.

The adhesive will begin to crystalise after around 8–10 hours and after 24 hours, the adhesive is brittle enough to allow the easy removal of the bonded inserts even at temperatures as high as 40°C. The remaining glue can then be scraped off and disposed of.
