Core binding agents

Waterglass WG are sodium silicates for the production of moulds and cores by means of the CO2 and ester process. They can be bonded with any dry and clean sand and used for the production of castings from GS, GJS, GJL, Al alloys and heavy metal castings.

Our waterglass WG can be delivered with or without disintegration conveyor and is thus optimally adjustable to the cast product.

100 WP quartz sand

3-4 WP waterglass WG

Amount of CO2 approx. 3% on sand or 16 litres / kg of sand


300 kg disposable drum (smaller containers on request)
