FIELD: metallurgy.
SUBSTANCE: invention relates to the field of foundry production, namely to compositions of mixtures for making molds and rods in heated tooling. Mixture contains, wt%: carbamidofuran binder 1.4–2.3, acid curing catalyst 0.3–0.8, powdered catalyst for synthetic resins 0.3–0.7, refractory filler 96.2–98.0, wherein the powdered catalyst for synthetic resins has the following composition, wt%: Fe2O3 46.0–50.0, FeO 10.0–12.0, Al2O3 1.4–1.5, CaO 1.2–1.3, MgO 1.5–1.7, SiO2 26.0–33.4, polydimethylsiloxane 6.5–7.5.
EFFECT: introduction of powdered catalyst for synthetic resins into composition makes it possible to increase its heat resistance.
