VINICOR® BEP-5297

Description

Two-pack epoxy enamel.
The base is a suspension of pigments and fillers in epoxy resin. Amine-type hardener.

Recommended use 

Designed for anti-corrosion protection of concrete, reinforced concrete and steel surfaces, internal surfaces of tanks, cisterns, tanks, silos and containers in contact with bulk and liquid food products when exposed to temperatures up to 60 ° C: cereals, sugar, flour, drinking water, beer, wine, fruit and vegetable juices, vegetable oil, fat-containing products.

In direct contact with food, white enamel is used, cream and gray enamel is also allowed for various structures in the perimeter of buildings and structures (surfaces of walls, floors, ceilings, columns subject to sanitary and epidemiological control).

Surface preparation

Metal surface:

• Degrease the metal surface to the first degree according to GOST 9.402

• Blast clean from scale, rust and old paint traces with a suitable grinding agent to achieve a surface with a sharp profile minimum to the degree 2 as per GOST 9.402; minimum to Sa 2 ½ degree with an angular sharp surface profile

Recommended roughness profile Rz = 60-80 µm (GRIT comparator as per ISO 8503-2; average roughness is between segments 2 and 3, but not less than the one of segment 3)

• Dedust.

Before applying the second layer, the coating shall be dry, clean and free of oil and dust.

Concrete surface:

Prepared for application of the paint coating shall be uniformly rough, have no protruding rebars, cracks, potholes, blowholes, sags, sheared ribs, oil spots, dirt or dust.

Operating procedure:

• Remove dirt, oil and grease contamination

• Remove lime (cement) milk, destroyed or peeling layers of concrete and old coatings by abrasive cleaning, grinding or brushing

• Dedust

• Repair cracks and chips.

The concrete base shall be cured for at least 28 days after concrete placement and before application of the primer; after application of levelling compounds – according to the regulatory documentation of the mixture manufacturer. Surface humidity (in a 20 mm thick surface layer) shall not exceed 4%.

Application 

• Before use, mix the base until homogenous
• While continuously stirring, add hardener to the base and mix thoroughly (the base/hardener ratio is indicated on the container and in the material quality certificate).
• The material is supplied with the viscosity suitable for application and does not require any dilution.

The pot life after of the mixed components depends on the ambient air temperature (decreased at higher temperatures) and is minimum 40 minutes at (20 ± 2)°С.
During application, the finished material shall be used within the specified time and the reduction of the pot life shall be considered when the ambient temperature is high!
The recommended temperatures for application in shop and field conditions are +5 to +30°С and the maximum relative air humidity 80%. The temperature of the surface to be painted shall be at least 3°C above the dew point.
The enamel prepared for application shall have a temperature of at least +15°C.
Before application of the basic enamel layers to the concrete surface, an impregnating layer shall be applied: VINIKOR-BEP 5297 enamel diluted with SOLVIN-13 solvent in the amount of at least 10% by weight. The impregnating layer hardening time before overcoating with the enamel layer depends on the ambient temperature, concrete surface condition and is minimum 16 hours at plus (20 ± 2)°С.

Storage and handling

The material is supplied in a package: base and hardener packed in metal buckets.
Storage conditions shall be in accordance with GOST 9980.5 (at ambient temperatures -40°C to +40°C). During storage, protect containers with material components from heat, precipitation and direct sunlight.
The warranty period of storage in a sealed container of the manufacturer of VINIСOR BEP-5297 primer components is: 12 months from the date of manufacture for the base, the warranty period for the hardener is specified in the hardener quality certificate.

Precautions

During the use of the product, observe the relevant industry standards and requirements, as well as the precautions indicated on the container label.
Use personal protective equipment (goggles, masks, respirators), avoid inhalation of solvents during evaporation and contact of the material or its components with skin, mucous membranes of eyes and respiratory tract; use indoors only if sufficient ventilation is provided.
The material and its components (base and hardener) are flammable! Hardened coating is not harmful for 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.
