*The products are supplied according to the supplier certificate.
**Applied simultaneously up to temperatures of 1,550 °C.
Notes to the table:
1. It is recommended that the maximum operating temperature of application established on mixtures be 100 °C-150 °C lower than the maximum specified temperature in a clean, non-aggressive, and neutral atmosphere of the thermal generating unit.
2. The "T" letter in the mixture grades means that the mixtures are intended for shotcreting; the "PC" letters mean that the mixtures are used in the petrochemical industry; the "LC" letters mean low-cement mixtures; the "ULC" letters mean ultra-low-cement mixtures; the "AN" letters mean that the mixture contains the basic refractory aggregate - andalusite; the "BR-P" letters mean that the mixtures are used for pouring refractory products; the "THW" letters mean that the mixtures are used for pouring thin-walled products.
