The combination of high thermal stability and low distortion exhibited by the ECOLOTEC process reduces the risk of penetration and veining defects. It contains no sulphur, nitrogen or phosphorous so surface defects associated with other resin systems are thereby reduced. As a result, the need for a coating is frequently avoided.

The ECOLOTEC process is the most environmentally-friendly gas cured organic resin process available and offers significant environmental benefits compared to other cold box process:

• non-flammable water based system;
• very low free phenol and formaldehyde
• no isocyanates, peroxides or heavy metals;
• no noxious fumes on mixing, coremaking or casting;
• low VOC (volatile organic compound) emissions;
• no effluent generated.

VAPOSET methyl formate set alkaline phenolic binder system

VAPOSET resin is a high performance alkaline phenolic sand binder which, when used with ester hardeners in vapour form, provides an excellent rapid cold box process suitable for both mould and core production.

VAPOSET resin is a low viscosity binder developed to give improved flowability, which leads to high strength development especially in terms of out of box strength.

VAPOSET is ideally suited to clean dry silica sand. Chromite, zircon and other sands can be used provided the different densities are allowed for.

VAPOSET has low fume evolution during mixing, casting and knockout stages. It exhibits excellent post casting breakdown and possesses superb stripping characteristics from all pattern types.
Casting surface finish is excellent on all metal types without the nitrogen, sulphur or phosphorous related defects associated with the use of other binder systems.

VAPOSET can be used in a unit reclaimed sand system or combined with reclaimed sand from cold set alkaline phenolic bonded sand.
