ISOLEP®-oil 250

Description

Double-packed epoxy composition hardened with polyamine hardener.

Recommended use

It is used as an independent coating for anticorrosive protection of the internal surface of steel  tanks, reservoirs, tank cisterns, industrial pipelines.
In the case of two-layer coating, it provides long-term protection in environments with high corrosive activity: in crude oil, bottom and sea water; chemical solutions with weak acid medium (pH 5-7)  and weakly alkaline (pH 8-11) media, washing fluids. In single-layer application, it protects the steel when it comes in contact with commercial oil, liquefied natural gas, lube oils and lubricants, lubricating fluids. The coating is highly abrasion resistant. Recommended operating temperature in liquid fluids is up to plus 60 °С (for a short time it is allowed up to plus 75 °С, it can stand steaming operation).

Approved by the test centers of OOO "Rutil", FAU "25th State Research Institute of Chemmotology of the Ministry of Defense of Russia".

Surface preparation

• to degrease metal surface to 1 degree according to GOST 9.402;
• to do abrasive blast cleaning of scale and corrosion to grade not less than 2 according

• to remove dust.

Application

Mix the base of material to a homogeneous condition before application; with constant stirring, add the hardener to the base, mix thoroughly for 2-3 minutes to a homogeneous condition.
The proportion of base and hardener: by mass 6.2:1, by volume 4:1

The material may be applied at an ambient temperature of plus 0 to plus 40 °C and relative humidity not more than 80 %. The temperature of the surface to be painted must be above the dew point by at least 3 °C, but not above plus 40 °C.
When painting, the temperature of the material must be not less than plus 15 °C, otherwise, it may be necessary to add a thinner to achieve an operating viscosity (not more than 5 % by mass). The addition of an oversize amount of thinner leads to paint drips and an increase in the hardening time of the coating. Dilution can also be used for roller / brush painting in case of coating repair. It is recommended to use both single-layer and two-layer coating depending on the operating environment (please refer to "Recommended use" or further clarify from the manufacturer).
Drying of the coating is natural. As the temperature increases, the drying time shortens. The minimum and maximum exposure time of ISOLEP-oil 250 coating before the next layer application (if necessary), as well as the time for its full hardening (start time for use) are given in the table (for a dry film thickness of 150 μm). The specified hardening time is recommended to be taken as indicative of practical coloring. The hardening time depends on the surface temperature and ambient air, the degree of dilution of the material, the thickness of the coating, the efficiency of ventilation and the relative humidity of the air.

Storage and handling

The composition is delivered in packages: base and hardener packed in metal buckets and metal cans.
Storage conditions – in accordance with GOST 9980.5 (at air temperature from minus 40 to plus 40 °C). The material components shall be stored away from heat sources, the container shall be protected from direct sunlight (short-term - not more than 3 hours is allowed) and atmospheric condensation. Shelf life of the composition base – 24 months and hardener – 12 months starting with the manufacture date.

Precautions

When working with the composition, the existing sectoral standard norms and requirements and safety measures as specified on the package label shall be observed.
Personal protective equipment (goggles, face masks and respirators) shall be used, and inhalation of thinners and contact of the composition or its components with skin, ocular mucosa, respiratory channels shall be avoided; use inside the premises is allowed only in case sufficient ventilation is provided. The composition and its components (base and hardener) are fire-hazardous!
The hardened coating is not harmful to human health.

The information is of general character, without consideration to the object specific nature. Use of materials for other purposes not specified here or in case other influencing factors are present shall be approved by the  VMP Holding CJSC  in writing. In case of absence of such approval the manufacturer is not held liable for the improper use of the material and the buyer falls from the right to present claims connected with the coating quality.
