Silica-organic composition of KOS 51-03 "heating" is intended to protect termoelektrodny wires microarmour, fuel elements and other equipment structures; for corrosion protection of metal and other surfaces, steel structures, pipelines and external insulation of heat pipes and steam pipes.
Produced and delivered KOS 51-03 complete with hardener tetrabutoxide. 50 kg of silica-organic composition, you need 0.1 kg of TBT.
Silica-organic composition 51-03 KOS is a suspension of pigments, silicate fillers and special additives in the silicone varnish.
Empty cans and dried-out residue of the composition render the collection of household waste.
The production of organic silicate compositions KOS 51-03 is performed on the basis THAT 2312-009-24358611-2011.
After drying the composition forms a homogeneous semi-gloss or matte surface without craters, pores and wrinkles;
Drying time KOS 51-03 up to 3 degrees at a temperature of 20°C does not exceed 4 hours;
When the temperature changes from 300°C to -60°C, the coating does not flake or peel;
The coating is heat resistant at a temperature of 300°C is not less than 3 hours.
The surface of components and structures to be painted shall not have burrs, sharp edges (radius less than 0.3 mm), sharp peaks at the welds, welding spatter. On the surface there should not be residues of flux, and moulding sand, scale, rust, grease and mechanical impurities.
After dedusting the surface is degreased with toluene or xylene. The degreasing of the surface is produced directly before application and not later than:
after 6 hours of machining when working outdoors
after 24 hours when working indoors.
However, at the conclusion of the head of the work surface may be degreased.
Use of the composition does not require priming of the metal surface.
Before use in prefabricated compositions it is necessary to add a curing agent TBT in the amount of 0.2 % by weight of the prefabricated kompozitsii.
TBT to pre-dilute the oil with solvent (toluene, xylene, orthoxylene, solvent) in a ratio of 1:20. Diluted TBT is added immediately before use of the enamel.
Prepared with the composition should be used within 24 h after mixing.
Prepared for the coating composition can be applied by spray gun, roller or brush.
