Furane resins of the Ekotec® series are intended for the preparation of self-curing moulding sands (cured by means of the “no-bake” method). Ekotec 45 and Ekotec 60 resins are recommended for the preparation of moulding sands and core sands for iron casting in foundries which do not employ sand regeneration. Ekotec 75 R and Ekotec 80 resins are recommended for iron casting in foundries where sand regeneration is used. Ekotec 90, due to the low nitrogen content, is used for the production of sand used in iron and steel casting.
