Intumescent fire retardants "Gefest" are able to provide high resistance of the structure to the effects of fire and high temperatures due to physical and chemical processes accompanied by heat absorption during the formation of a charred layer with high heat-insulating ability on the protected surface.
GEFEST fire retardants are produced in three modifications: for metal structures GEFEST OSM-1, for wood and materials based on it GEFEST OSD-1 and for cable products GEFEST OSK-1.
GEFEST fire retardants are supplied as a one-component, ready-to-use white substance.
The improved technology for the manufacture of compositions has positively affected the technological and fire retardant parameters of GEFEST fire retardant compositions. The fire-retardant composition "GEFEST" is able to provide the fire resistance limit of metal structures up to 120 minutes.
The composition is packaged in cans of 50 kg. At the request of the customer, flame retardants (from light to intense shades of gray, red-brick, etc.) can be tinted at the factory without loss of fire retardant properties in a limited number of shades.
