Furan resins
Ideal for producing moulds and cores for high-quality grey cast iron, ductile iron and cast steel. Their low free formaldehyde content makes them more environmentally compatibility and improves working conditions. The fast reaction of the binder accelerates production and increases productivity.
Smaller additions of binder and hardener reduce gas formation, produce a smooth surface and improve economic efficiency. FRN-100 is a low-nitrogen, phenol-free resin with low levels of free formaldehyde.
Hardeners for furan resins
Our range of EUH hardener products was developed specifically for cold-setting FRN resin. EUH hardeners are low viscosity products that mix well with sand. SQ furan resins react quickly, which reduces production time and improves productivity.

Phenols for the shell moulding process
In the shell moulding process, a mineral, usually quartz sand, is coated with novolac resin as a binder typically with hexamethylenetetramine used as a hardener. Release agents, e.g. sodium stearates, are added to improve flow and prevent sand agglomeration.
