However, the paint composition does not provide the possibility of its application to a damp surface or the surface under the water.

The task, which directed the claimed solution is to enable the coating composition on the wetted surface or the surface under the water.

Technical R is the result, achieved when the task is providing the possibility of formation of waterproofing and corrosion protection of metal and concrete surfaces of the port facilities, ship structures, to protect them from acids, alkalis, and salt water, as well as the repair works directly on site without dismantling of buildings or parts thereof).

The problem is solved in that the paint composition consisting of bases, including 40-70 % by weight of the basics epoxy Dianova resin modified coal, preferably liftability, resin, pre-stabilized hexamethylenetetramine, red iron oxide, and/or white carbon and/or aluminum powder as the pigment is a water-soluble solvent, Salvaterra capacity of not less than that of water, in an amount of from 10 to 30 % by weight of the base, if necessary, talc and/or silica sand as a filler in an amount up to 30 % by weight of the base and hardener amine type.

Table 2 and table 3 contain examples of variations of the formulations and the corresponding variations of the properties of the composition, which is the basis for the substantiation of the structure of the paint composition.

For the preparation of foundations used:

- low molecular weight Dianova epoxy resin ED-20, E-16, e-40 with molm 400-800, the epoxy resin according to GOST 10587;

- coal tar liftability on THE 14-7-100 obtained by coking liftability coal and has the following characteristics: density at 20±2°C, g/cm31,02-1.1 refractive index 1,588±0,002; group composition (% by weight), phenols 8-18, paraffins and olefins 4-12, neutral oxygen compounds 20-30; carboxylic acid 1-2; pyridine bases 1-3; aromatic hydrocarbons 22-34);

As a hardener for the manufacture of a composition is applied Triethylenetetramine on THE 6-02-1099-77.

Hardener take in the amount of 3.3 to 8.2 parts by weight per 100 parts by weight of base.

As a solvent for the manufacture of a composition applied water-soluble solvents, Salvaterra capacity not less than that in the s, for example dimethylformamide (DMF) according to GOST 20-289-74 or dimethylsulfoxide (DMSO) according to GOST 46-09-38-18-77 or Diisopropylamine.

The composition is prepared and used as follows.

When preparing and using the paint composition must meet the known range of security measures.

The components for the composition is prepared as follows.

Stabilize liftability coal tar, adding hexamethylenetetramine in effective amounts (for its weight ). When interacting liftability coal tar with hexamethylenetetramine, which is the donor and methylene amine groups are formed oligomers of type alkylphthalimide and alkylphenolic resins (which reduces the number of free phenols), as well as other compounds of unknown structure, which causes corrosion properties, transform, corrosion products, away from the protected surface water and hydrophobizing the surface of the coating film after curing.

The basis of the composition obtained by mixing epoxy Dianova resin and stable liftability coal tar in the stated proportions. Filler and pigments also enter the basis, then the mass of the fray in a ball mill until the degree of dispersion of 40-50 μm on the wedge (GOST 659-57). Iron oxide red, in addition to dyeing compositions, while "works" and as a "filler" songs, and as a solid filler interaction which occurs with the active functional groups of phenols liftability resin. The reaction due to the presence of highly polar hydroxyl groups in the phenol. In reaction formation reaction, in which further catalysts in the polymerization of epoxy-liftability system. As a filler role rigid reinforcement in utverzhdenii epoxy-liftability system, use quartz sand, which is the high modulus filler. When deformation of the filled epoxy-liftability system sand, little deformed because its modulus of elasticity is thousands of times greater than that of the polymer matrix, therefore, the deformation of the material of the composition is effected by deformation of the polymer matrix.

To facilitate dispersion and decrease the duration of the basis add up to 30% by weight of the basics of water-soluble solvent, Salvaterra capacity of not less than that of water (for example, dimethylformamide, or dimethylsulfoxide, or diisopropylamino).

The finished base paint composition Packed in metal sealed eat the spine according to GOST 9980.3. Hardener for her (Triethylenetetramine) is placed on THE 6-02-1099.

Warranty period of storage of the basis set 6 months from date of manufacture. When using the bases after the warranty period of storage before using it you need to spend quality control. Warranty period of storage of the curing agent is determined by THE 6-02-1099.

To obtain a paint composition of the mixed base and hardener (curing agent in the range of 8-20% by weight of epoxy resin, and the higher the share of such resins in relation to coal tar, the higher should be the content of the curing agent in the composition).

The composition is diluted (if necessary) a water-soluble solvent (Salvaterra capacity of not less than that of water) to working viscosity by viscometer VZ-1 at 20±5°C. the Amount of solvent should not exceed 30% by weight of the composition.
