VINICOR® EP-5285

Description

Two-component polyamine cured epoxy enamel/

Recommended use 

Special anti-corrosion protection of nuclear power plants structures and radiochemical production: various surfaces of premises (walls, ceilings, floors), pipelines and equipment operated in the controlled areas of NPP and exposed to decontamination solutions. Protection of metal structures in the aquatic environment and atmosphere, including nuclear waste storage containers.

Certificates, Approvals

State registration certificate No. RU.77.01.34.008.Е.003091.11.19 dated 29.11.2019. Nuclear industry: conform to GOST Р 51102 requirements “Decontaminable protective polymeric coatins”, decisions of the Federal State Unitary Enterprise “A.P.Alexandrov Research Technological Institute”, AO “Research and Construction Institute of Erection Technology-Atomstroy”.

Surface preparation

As an independent coating on steel surfaces:

• degrease the metal surface to 1 grade according to GOST 9.402;

• perform abrasive-blast cleaning from scale, corrosion products and old coatings to at least Sa 2

• ½ grade according to ISO 8501-1 or mechanical and manual tool to St 3 grade according to ISO 8501-1;

• remove dust.

As an independent coating on concrete surfaces:

The exposure of the concrete base after laying concrete before applying the VINICOR EP-5285

enamel should be at least 28 days; after application of leveling mixtures - according to the regulatory

documentation of the mixture manufacturer. Surface humidity (in the surface layer 20 mm thick) not more

than 4 %.

Surface prepared for application of coating shall be evenly rough, without protruding fittings, cracks,

pot-holes, popouts, overlaps, arris spalling, oil stains, dirt and dust.

Quality management system

is certified according to ISO 9001

page 2 of 3 VINICOR EP-5285, date 10.01.2020 г.

This document supersedes those previously issued

The operating procedures:

•  remove dirt, oil and grease;

• remove lime milk (cement slurry), destroyed or flaking concrete layers and old coatings by abrasive cleaning, grinding machine or brushes;

• remove dust;

• repair crack bridging and spalls.

Repair painting:

• degrease the metal surface to 1 grade according to GOST 9.402;

• mechanically or manually remove locally all the way to the metal to 2 grade according to GOST 9.402 (paragraph 5.18) or to P Sa 2½ grade, to Р St 3 grade according to ISО 8501-2 (thorough local cleaning), trying to make a smooth transition from coating to refined metal;

• remove dust.

Primed surface:

The coating of the underlying layer should be cleaned of dirt, if necessary, degreased, and free from dust and moisture.

Before applying the second coat, the coating must be dry, clean and free from oil and dust.

Application 

•  mix the base thoroughly to homogenous condition before application;
  
• with constant stirring, add the curing agent to the base and mix thoroughly (the ratio of the base and curing agent stated on the label of the package and in the material quality certificate);
• if necessary, the composition should be diluted to the working viscosity.

• by airless and pneumatic spraying methods in 1-2 layers to achieve the project coating thickness;
• by electrostatic spraying method in 1-2 layers upon dilution with thinner RE-11V (РЭ-11В);
• by brush or roller in 2-3 layers.

Storage and handling

The material is delivered in packages: the base and the curing agent packed in metal containers respectively depending on the set weight.

Storage conditions – the base according to GOST 9980.5 (at air temperature from minus 40 to plus 50 °C); the hardener according to GOST 9980.5 (at air temperature from plus 5 to plus 50 °C). The container with the material components shall be stored away from heating sources, protected from atmospheric condensation and direct sunlight.

The shelf life of the base and hardener is 12 months from the manufacture date.

Precautions

When working with the enamel-primer one shall observe the existing sectoral standard norms and requirements and safety measures as specified on the package label.

One shall use personal protective equipment (goggles, face masks and respirators) and avoid inhalation of solvents and contact of the composition substances with skin, eye mucosa, respiratory channels; use inside the premises is allowed only in case sufficient ventilation is provided.

The enamel is classified as fire-hazardous material.

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.
