KM I-CHAR 22 SOLVENT-BASED INTUMESCENT PAINTS  FOR THE FIRE PROTECTION OF  STEEL STRUCTURES

KM I-CHAR 22 SOLVENT-BASED INTUMESCENT PAINTS FOR THE FIRE PROTECTION OF STEEL STRUCTURES

KM I-CHAR 22 is used for the fire protection of steel structures, concrete, reinforced concrete,

compartmentation masonries in brick or concrete and in other fields of application.

It guarantees a class of fire resistance up to 2 hours.

KM I-CHAR 22 is an high performances solvent-based intumescent paint. The active solids, the strength of

the intumescent foam with excellent working capacity guarantee an efficient fire barrier.

The fast development of a stable carbon foam with low coefficient of heat transmission guarantees an

efficient protection of the flammable and inflammable substrates.

The solvent-based KM I-CHAR 22 guarantees many advantages of application in difficult environmental

conditions, low temperatures, high humidity and resistance against rain.

  • KM I-CHAR 22 is used for the fire protection of steel structures, concrete, reinforced concrete,

    compartmentation masonries in brick or concrete and in other fields of application.

    It guarantees a class of fire resistance up to 2 hours.

    KM I-CHAR 22 is an high performances solvent-based intumescent paint. The active solids, the strength of

    the intumescent foam with excellent working capacity guarantee an efficient fire barrier.

    The fast development of a stable carbon foam with low coefficient of heat transmission guarantees an

    efficient protection of the flammable and inflammable substrates.

    The solvent-based KM I-CHAR 22 guarantees many advantages of application in difficult environmental

    conditions, low temperatures, high humidity and resistance against rain.

    (Intumescence is the “swelling during carbonization”).

    Special chemical compounds react with temperature exceeding 200°C, forming a low density foam of

    volume up to 100 times the original mixture. This foam guarantees an efficient barrier against the heat

    transmission, protecting the substrate.

    The fire resistance of the structures are very important for the security in case of blaze. In case of fire in

    buildings, factories, hotels, airports, malls, schools, hospitals, cinema, theaters, multilevel carparks etc., the

    intumescent paints increase the strength of the structures, and they allow to save lives, preserving the

    structure, to allow the carrying of the occupants and the working of firemen.

    USE AND APPLICATION

    An adequate preparation (cleaning, degreasing and removal of fine particles) is necessary.

    The steel surfaces are normally sandblasted (SA21 ½), before applying an anticorrosive primer.

    Two hands of paints are at least to apply by airless systems, by crossing wet-on-wet.

    A typical application of 1,5 mm (dry product)=2,7 kg/ m2

    (wet product) is made by two hands with a wet

    layer 1 mm thick.

    A right equipment is an airless piston pump, minimum compression ratio =40:1, minimum pression 150 bar

    (for example GRACO MARK V or WAGNER ProSpray PS34), self-cleaning nozzle Reverse-A-Clean, nozzle

    diameter 45-50 mils = 1 mm, flexible feed hose of 3/8“ and maximum 30 m long. In the normal spry

    applications, the medium volume flow changes between 3 and 6 l/min.

    All filters of the equipment should be removed after every operating.

    The application may be also done by brush or roller, with long single coats, without brushing. The

    brush/roller application will require more hands than the airless one.

    During the application and the drying you will have to work under appropriate environmental conditions. 

    DATA SHEET

    PRIMER AND RACCOMENDED FINISHES

    KM I-PRIMER 036: Fast drying phenolic modification alchidic primer for steel and galvanized steel.

    Different commercial primers are compatible. Our technical department may provide a list.

    KM I-CHAR 22 is compatible with alchidic systems.

    A better appearance and a less grip of dirt can be obtained by a finishing.

    The intumescent paints can’t be used in the presence of condensation or rain, in wet environments and

    outdoor. Waterproof finishes are necessary.

    Any finishing isn’t generally required indoor according ETAG 018, class Z1 and Z2. Our acryilic waterbased

    paint IDROSOL is used on semi-exposed environments according to ETAG 018, class Y. Our bicomponent

    polyurethanic solvent-based PURETHAN is used on outside and totally exposed according to ETAG 018,

    class X or ISO 12944, corrosion class C3. The application must be particularly careful.
