Casttec 42

Casttec 42 is a light-brown, general-purpose precast adhesive designed to offer a strong, secure bond between wood, plastic, metal, and foam. It can be applied over a light oil, removing the need to clean surfaces before application.

Casttec 42 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. The remaining glue can then be scraped off and disposed of.
