Core jointing compound – air hardens – the permanent bond between two dry sand surfaces
Desco (Core Glue)
Desco is an air-hardening liquid core jointing compound that air hardens at room temperature to
produce a strong permanent bond between two dry sand surfaces. Desco is applied as a thin
cream liquid to the two halves of the core, which are then pressed firmly together, and left for the
joint to air harden. This material is particularly recommended for joining cores manufactured
from
* CO2 Silicate bonded sands
* resin bonded sands.
* oil-bonded sands
Desco is recommended for all types of core joining including the repair of dry sand mould and
cores as the low volatile content avoid the danger of blown castings.
