CFX-27 is gray, self-hardening to adhesive of cores.
CFX-27 is an air-hardening paste for jointing moulds and cores that are produced by both
silicate mould and shell mould.
Cores after jointing by CFX-27 can be set in about 5-10 minutes because of good
air-setting property; full hardening will be 90-120minutes.
CFX-27 can be used as mould sealer for silicate or furan mould.
CFX-27 is very easy to use in either cores or moulds, because tube packing has been
applied. Squeeze the tube let cfx-27 flow on each joint faces and two parts of the joint are
the pressed tightly together, to short the setting time, allow the surface to become tacky
before putting the faces together.
