Latik (fire-retardant varnish composition) for timber (KrilaK)
Clear fire-retardant varnish system for timber structures and interior finishes, group I, KM1, preserves the wood texture.

Joker EP is a two-component compound based on epoxy resin with a hardener, intended among other things for special-purpose facilities. Per GOST R 53295-2009 it belongs to fire protection performance group 1 (up to 180 minutes). The coating works indoors and in the open atmosphere: UKhL-1 version per GOST 15150-69, corrosivity categories C1–C4 per ISO 12944-2, service temperature from −60 to +60 °C. When applied below +10 °C, the material is warmed to +15…+20 °C.
