MONOLITM1 – Fire-retardant composition

1. FIELD OF APPLICATION AND PROPERTIES

Fire-retardant composition "Monolit M1"is a combination of mineral binder and special-purpose additives and fillers.
Coating made offire-retardant composition"Monolit M1" is designed to protect bearingmetal primed structures.The coatingneither cracksnor flakes from the surface, it can endure small deformation, impactsand otherdynamic loads, it is tolerant to mechanical cleaning,agressive substancesand special treatments, it does not contain asbestosand other substances considered harmful for health and environment.

2. NORMATIVE AND TECHNICAL REQUIREMENTS

Fire-retardant composition "Monolit M1" corresponds togroup 1 fire safety requirementsstipulated byNPB 236-97 "Fire-retardant compositionsfor steel structures. General requirements. Method of fire safety effectiveness determination"; it can increasethe fire rateof metal structures up to240 minutes.

4. SURFACE TREATMENT

Coating should be applied on the primed load bearing metal structures (columns, joists, stiffeners, etc.). The recommended anticorrosion coatings: “GF-021” (glyptal based primer). Dust and dirt should be removed from the surface by means of wet rags, grease and oil stains can be removed with solvent (solvent 646 is recommended). If application of solvent is not possible use the washing agents.

5. APPLICATION

Application conditions
Ambient temperature should be not lower than +3 °;
Relative air humidity should benot more than85%;
The temperature of the surface treated should be higher than dew point bynot less than3 .
Application mode
The coating should be applied by means of priming machines (-154 , -103, -1, ISO-P5). The machine should be supplied withcomposition "Monolit M1"and waterin ratio of1:1. This solution should beapplied onto the surfaceof the structure in several passesdepending on the required thickness of the fire-retardant coating.
Interlayer drying-out period amont to 2- 6 hoursdepending on the ambient temperature and relative air humidity.
Cleaning of tools
The tools should be washed immediately after completion of application.

6. OPERATING CONDITIONS AND LIFETIME OF THE COATING

The coating may be used both indoor and outdoor. Operationaltemperature range is -40…+40 .
The lifetime of the coatingis not less than 50 years.

7. PACKING AND STORAGE

Fire-retardant composion "Monolit M1"isdelivered in 30 kg bags.
Shekf lifeindooris1 year withrelative humidity not more 85%and under temperature not higher than+40 .
