The need for Cold Box binder technology that delivers higher productivity and improved casting quality with reduced environmental impact has led to the development of a range of high performance POLITEC binders, for use in ferrous and non-ferrous foundries.

A range of binders which offers excellent core strength, ensuring consistent production of even the most complicated cores with reliable dimensional accuracy. The bonded core is very stable, allowing for the use of water-based coating without degradation.

The high reactivity of the products ensure amine consumption is minimised, whilst reducing gassing times and improving productivity. These benefits can be enhanced further by the use of the Politecplus amine (TMA) gassing process. Viscosity of the products is optimised to provide improved sand flowability, whilst reducing resin wipe-off and core sticking.

POLITEC cold box system has the following resins: POLITEC CB1000, POLITEC CB1200 and catalysts TEA or DMEA. Addition rates vary from 1.0% - 2.0% total resin with a ratio of 50:50 to 55:45. New or reclaimed sand can be used. POLITEC is best suited for iron and non ferrous castings, as defects may occur with steel due to erosion.
