A two-component epoxy compound with increased non-volatile content with solvents for priming and levelling concrete and other mineral substrates.
The compound is intended for penetration, stopping and priming of concrete and other mineral substrates in order to dedust, harden, waterproof, increase oils resistance, gasoline, aggressive chemicals, increase the subsequent coatings adhesion to the substrate. It is used as an intermediate layer primer composition when producing a thin-layer, monolithic, heavily filled polyurethane, polycarbamide and epoxy coatings for concrete surfaces in industrial, commercial, residential and public buildings and structures, transportation facility, warehouses, terminals, parking lots, as an insulating lining for collectors, reservoirs, artificial reservoirs, etc.
Material advantages and features
It can be applied on a wet surface;
It can be used as an uncoloured independent topcoat or with quartz and other coloured filler.
The material can be used as an independent or intermediate layer coating. Defens PE-03 mixture with a dry filler is an effective tool for stopping and repair of concrete and cement substrate.
It penetrates deeply into the substrate with additional compound desaturation and has high adhesion to various surfaces;
It is waterproof and resists negative hydrostatic pressure;
Does not have a harmful effect on the environment after complete polymerization;
Almost does not shrink when used as a stopping or topcoat composition;
Provides high hardness, wear resistance to mineral and concrete substrates;
Easy to use and safe material for professional use.

Recommendations for use
Concrete substrate properties and preparation requirements
Concrete substrate properties and surface preparation methods must comply with the current construction and technical standards. The substrate must be solid, homogeneous, clean, dry, free from oils, fats, crumbling areas, old coating flaking residues and other contaminants that prevent adhesion. Concrete substrate basic requirements: compressive strength — not less than 20 N/mm2, tear strength — not less than 1.5 N/mm2. The substrate residual moisture content shall not exceed 4% by weight. Concrete substrate shall be treated with abrasive tools, bead blasting, milling or grinding equipment. For concrete floors with a reinforced top layer, only bead blasting is allowed. The dust formed during processing shall be carefully removed with an industrial vacuum cleaner.
Application conditions requirements
The compound components temperature, substrate surface temperature and the ambient air temperature in the work area: from + 5°C to +25°C.
Attention! The substrate surface temperature shall be at least 3°C above the measured dew point during both the compound application and primer layer complete polymerization /drying required time. Relative humidity: not more than 70 %.
Application method
Pour the entire volume of the comp. 1 and 2 in a mixing container of the appropriate volume and mix thoroughly until smooth for 2-3 minutes. To mix the components, use a low-speed (300-400 rpm) mixer with an electric drive. It is necessary to fill up the uncured primer layer surface with dry quartz sand fraction (0.1-0.3) mm or (0.4-0.8) mm in order to provide adhesion with the topcoat.
DO NOT MIX COMPONENTS MANUALLY!
Attention! Depending on the components reactive capacity, the epoxy composition curing process is accompanied by the release of a certain amount of heat. Epoxy composition mixture self-heating in the mixing tank can provoke its premature curing. Therefore, it is strongly not recommended to leave the prepared epoxy composition mixture directly in the mixing tank for a long time.
Application method: brush, roller, spatula.
Packaging and storage
The composition is supplied in sealed metal containers. The kit consists of two components (A, B), total weight — 10 kg; 20 kg. Store the primer in tightly closed containers, keep away from moisture, direct sunlight, and heat sources, at a temperature of + 5 to + 30°C without condensation. The storage warranty period is 12 months from the manufacture date subject to compliance with the storage conditions.
Tools cleaning
Work tools and equipment shall be washed with a solvent P-5, Р-646 immediately after use. The cured composition can only be removed mechanically.
Security precautions
It is a fire-hazardous material. Persons working with epoxy composition shall be provided with personal protective equipment. All work shall be carried out in rooms equipped with supply and exhaust ventilation. In case of contact with skin or eyes, rinse thoroughly with water and seek medical advice if necessary. After complete drying and polymerization, the primer (stopping filler) layer is completely safe and allowed for operation as part of seamless polymer coating systems in public, residential and industrial premises, including food production, catering, pharmaceutical industry, agriculture, in rooms for children and medical institutions.
When carrying out work, use personal protective equipment, avoid contact with eyes, respiratory tract and skin. Keep away from fire.
