Self-hardening binder based on alkyd resin containing modified oil, hardened with isocyanate (Catalyst KL).
Binder SL is used to produce moulds and cores. We may use quartz or chromite sands as a mineral base. Sands containing this binder are used first of all in production of cast steel castings. In cast steel foundry engineering they compete with self-hardening sands containing phenol and furfuryl resins.
