Advantages: Enamel forms of coatings for chemicals and physical properties of chemicals. It is a combination of high-quality anti-corrosion, anti-corrosive and anti-corrosive coatings.
The enamel coating is resistant to minus 60 ° C to plus 70 ° C.
Surface preparation:
The enamel is carried out in accordance with 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.
It is applied to the “strip layer”. It has been found that it has been mechanically cleaned, degreased and dried. It should be checked for compatibility. In case of old coating, must be removed. After 4 hours after the final surface preparation.The color of water should not be below 3 ° C.
Coating: E mal EP-152 is an applied by pneumatic, airless and electrostatic spraying. Brush applied.
Before applying the prefabricated enamel must be thoroughly mixed, up to 100 mh add 0.55 pm hardener pep or 1.1 mh hardener no. 1, mix, filter and hold for at least 30 minutes. R-5A or R-5 (GOST 7827) for application by pneumatic spraying, it is diluted with a solvent of 50%. an amount not more than 5% by weight of enamel. Enamel can be applied with an initial viscosity.
When spraying in an electric field, the enamel is diluted with an
RE-152 is a solvent that has been approved for the consumer.
It is not less than 15 ° C and a relative humidity of 80% in two layers. The thickness of the dried two-layer coating should be 80 – 100 microns.
EP-045 epoxy primer (
manufactured by Lakokraska) and an complex coating thickness of at least 200 microns.
Life Service : The coating system, consisting of one EP-045 primer layer 40 microns thick and two EP-enamel layers 152 to 120 microns thick, retains protective and decorative properties in a moderately cold climate for at least 15 years.
Of The ENAMEL consumption for a to two two-dried coating of layer with a thickness of
80–100 µm is 340–380 g / m² without need to take into account the surface, color, and other factors.
Drying time of 40 to 50 microns depending on temperature:
| Name of the indicator | Surface temperature | |
| 15 ° С | 20 ° С | |
| It will be the time when it comes to otlip, min, not less. | 60 | thirty |
| Drying time to degree 3, min, not less | 80 | 60 |
| Time, min, not less | 80 | 60 |
Can be used only as recommended. In particular, it is possible to reduce the amount of heat, it is not necessary to reduce the amount of heat, it is not necessary to reduce the heat loss.
Enamel drying is allowed at a temperature of (70 ± 2) ° C for at least 35 minutes.
Prior to commissioning the painted product is recommended to withstand at least 7 days.
Precautionary measures are taken carefully and carefully. Wear rubber gloves to protect hands.
