SURFACE PREPARATION
New steel surfaces:
degrease metal surface to the first degree according to GOST 9.402;
abrasive blasting of scale, rust to the degree of 2 according to GOST 9.402 (to the degree of Sa 2 ½ according to ISO 8501-1); the surface profile is sharp, angular with a roughness of 30-75 microns according to ISO 8501-1; in hard–to-reach areas of the surface, cleaning to the degree of Sa 2 or St 3 according to ISO 8501-1 is allowed.
For temporary protection of metal structures, if necessary, use a shop-primer.
Before applying the main coating, the shop-primer coating must be cleaned of grease and other contaminants, dust-free, damaged areas must be cleaned and restored with ISOLEP-235.
Repair and maintenance:
degrease metal surface to the first degree according to GOST 9.402;
remove salts using fresh water;
the damaged areas should be cleaned with mechanized and manual tools from rust to the degree of St 2 according to ISO 8501-1; with the use of abrasive blasting and more thorough surface preparation (up to Sa 2 - Sa 2 ½ according to ISO 8501-1), it is possible to improve the operational characteristics of the coating.
remove dust.
It is allowed to clean by high pressure water jetting (pressurized to above 70 MPa) to Wa 2 and flash rust grade not lower than M (ISO 8501-4)
Painted surfaces
Before applying subsequent layers, the coating surface must be cleaned of dirt, degreased and free of dust.
Preparation of other surfaces
The coating can be used to protect stainless and galvanized steels, aluminum.
INSTRUCTIONS FOR USE
mix the primer-enamel base to a homogeneous condition before application;
with constant stirring, add a hardener to the base, mix thoroughly; if necessary, dilute to working viscosity.
Viability of the primer enamel (after mixing the components) at ambient temperature (20 ± 0.5) °C is at least 2 hours (when organizing painting work, a decrease in viability should be taken into account when the temperature rises).
The material is recommended to be applied at ambient temperatures from minus 10 to plus 40 ° C and relative humidity up to 85%. The temperature of the painted surface must be at least 3 ° C above the dew point.
When painting at low temperatures, the temperature of the ground enamel should be at least plus 15 ° C.

solvents of grades 646, P-4, 647, 649.
Adding too much solvent will cause sagging and increase the curing time of the coating.
The curing time of the ISOLEP-235 coating before applying the next layer of the composition and before overlapping with coating enamels is at least 6 hours at ambient temperature (20 ± 0.5) ° C.

The curing time is recommended to be taken as an indicative (it depends on the surface temperature and ambient air, the degree of dilution of the material, coating thickness, ventilation efficiency and relative humidity), the actual time should be determined empirically when painting under specific conditions. The maximum overlap time of the subsequent layer is 7 days. If the overlap time is exceeded, before applying the next layer, the coating should be roughened by abrasive blasting (swiping), mechanized or manual tools.
STORAGE OF ANTICORROSIVE PRIMER ENAMEL
The material is supplied as a complete set: the base and hardener are packaged in metal buckets and metal cans, respectively, depending on the weight of the kit.

The components shall be stored away from heat sources, the container shall be protected from direct sunlight (short-term exposure, not more than 3 hours, is allowed) and atmospheric condensation.
The shelf life of the base is 24 months, the curing agent - 12 months starting with the manufacture date.
SECURITY MEASURES
When working with the composition, the relevant industry standards and requirements should be observed, as well as the precautions indicated on the packaging label.
It is necessary to use personal protective equipment (glasses, masks, respirators), avoid inhaling solvents during evaporation and getting the composition on the skin, mucous membranes of the eyes and respiratory tract; use indoors only with sufficient ventilation.
The composition refers to fire-hazardous materials.
