Type: EP-045, EP-045 K two-component epoxy primers consist of a semi-finished product and e-45 hardener. Semi-finished products primers are a suspension of pigments and fillers in a solution of epoxy resin with the addition of targeted additives and solvents.
Scope: Primer EP-045 is intended for high-quality anticorrosive protection of products from metals (carbon and galvanized steel, copper, aluminum and its alloys), in machine, machine, car and shipbuilding, construction, urban economy, etc., and also when carrying out repair work. The
EP-045 K primer is used to protect and paint partially corroded metal surfaces with a tightly held rust thickness of up to 100 microns, which is difficult to thoroughly descale.

Benefits:
Primer EP-045, due to the effect of anti-corrosion pigments, effectively protects the product from corrosion.
The primer EP-045K combiners converter and anti-corrosion coatings.
Primers have excellent adhesion to metal and high hardness.
EP-045, EP-045 K coatings for dries quickly, without a trace.
Surface preparation.
The primer painting is carried out in accordance with the product, GOST 9.402 or
STB ISO 12944-4.
Oil, grease, paint, dirt and other substances, such as mineral contaminants, water-soluble salts, It is necessary to remove incisions, burrs, welding spatters, round sharp edges, teeth and welding seams. It should be thoroughly cleaned, dust-free, degreased and dried. It is the most up to 3 cm wide range of residues from fluxes, alkaline slags and oxides formed during welding.
It is recommended to improve the protective properties of the surface oxides 1 – 2 according to GOST 9.402.
Application : Primer is applied by pneumatic, electrostatic, airless spraying. It is allowed to apply primers with a brush or roller.
Before use, mix semi-finished primers, add hardener E-45 in the ratio: 100 meters. Semi-finished primers – 14 meters. P-5A or P-5 Hardener, mix again and incubate for 15 – 30 minutes and dilute with solvent, in the amount of 5 – 30% by weight of the primer. Solvent P-4 (GOST 7827) is allowed. The primer brush is applied to the initial viscosity. When applying primer EP-045, the primer is diluted with solvent RE-4B (GOST 18187) in an amount of 30%. Primers are not less than 10 ° C and a relative temperature of 80% in one to two layers.Drying time of 30 – 40 microns – no more than 6 hours at a temperature of (20 ± 2) ° C. Drying time temperatures: at a temperature of (80 ± 2) ° C for 40 minutes; at a temperature of (60 ± 2) ° C for 60 minutes.
It is not less than 40 microns; This is a layer of surface roughness Ra (GOST 2789). Increasing the protective properties. It’s necessary to preserve the primed surface.
There is a possibility that the consumption of 40 μm is 120-130 g / m².
E-45 is not less than 8 hours at a temperature of 20 ± 2 ° C.
Precautionary measures are carried out carefully and carefully. Wear rubber gloves to protect hands.
Storage: Store the container prefabricated in a tightly closed container, protected from moisture and direct sunlight. Keep away from fire!
