Recommended use

It is used as a single coating system for anticorrosive protection of the internal surface of steel tanks, reservoirs, tank cisterns, industrial pipelines.

 

Specifications

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).

 

AREAS OF APPLICATION

The composition ISOLEP-oil 250 is designed specifically for anticorrosive protection of oil and gas facilities.

SURFACE PREPARATION

degrease metal surface to the first degree according to GOST 9.402;

Perform abrasive blasting to grade not less than 2 according to GOST 9.402 or Sa 2 ½ according to ISO 8501-1. Surface profile is sharp, angular with a roughness of 85-115 microns

(3G segment according to ISO 8503-2);

remove dust.

The material should be applied no later than 6 hours after abrasive blasting. If it is necessary to apply a second layer of material, the application surface must be clean from dirt, degreased, dust-free and dry.

 

INSTRUCTIONS FOR USE

Mix the base 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 pot life (after mixing the components) at ambient temperature (20±2)°C is not less than 1 hour.  For the organization of painting, the decrease of the pot life with increasing temperature should be taken into account.

 

The material may be applied at an ambient temperature of 0 to plus 40 °C and relative humidity not more than 80 %.

 

The temperature of painted surface should be at least 3 °C above the dew point, but not above plus 40 ° C.

 

When painting, the temperature of the material must be not less than plus 15 °C.

 

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 coating is natural. As the temperature increases, the drying time decreases.

 

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 microns).

The specified curing time is recommended to be taken as an indicative for practical painting. The curing time depends on the surface temperature and ambient air, the degree of dilution of the material, coating thickness, ventilation efficiency and relative humidity.

 

If the maximum overlap time is exceeded, it is necessary to carry out an additional surface treatment for roughening (light sweeping).

 

STORAGE AND HANDLING

The material is supplied as a complete set: base and hardener, packed in metal buckets and metal cans.

 

Storage conditions is in accordance with GOST 9980.5 (at ambient temperatures from minus 40 to plus 40 °С).
