Casttec adhesive

Casttec adhesives

The casttec® hot melt glue system has enough open time to allow workers to position inserts in the form. Its high molten tack holds inserts securely in place instantly, even during pouring and vibration of the concrete. After casttec® has set, it slowly crystallises and becomes brittle. This makes it easier to de-mould and clean-up, even with automated processes. Casttec® bonds on light form oil, so there is no need to remove the oil from surfaces before glue application. Surfaces should be free of dust and dirt which could prevent the adhesive from grabbing the form.

Casttec® adhesive

Casttec® hot melt glue works on most materials: steel, extruded and expanded polystyrene foam, wood, PVC, LDPE and most other plastics.

This eliminates the need for multiple attachment methods or expensive special inserts that are compatible with magnet systems. Unlike other adhesives, there is no build-up of residue, which causes extra cleaning time with solvents or grinders that can harm the appearance of the finished parts.
