NEFTECOR® primer

Description

Double-packed epoxy primer.
Used as  a  primer  layer  in the complex system with the  NEFTECOR  enamel. The material is  thixotropic, has a  low content of organic thinners, allows to obtain a thick-layer coating. The coating is  resistant to short-term acid solutions attack. The complex coating  –  NEFTECOR orange  primer with NEFTECOR white enamel  –  is applied  for  contact with light oil products (aviation fuel).

Recommended use 

Anticorrosive  protection of steel  surfaces  operated under the influence of crude oil, aviation and  automobile fuels, lubricating oils, diesel fuel, kerosene, fuel oil, fresh,  sea, "bottom-up" water, alkali  solutions.
It is used in a complex coating with the NEFTECOR enamel for painting of oil storage tanks, light and  dark petroleum products, pipelines, and other metal structures used in aggressive conditions.
It is used to protect the metal structures used in the soil, immersed in various liquid media. Certificates, approvals Certificate of State registration No. RU.77.01.34.008.Е.002295.08.18 dated 28.08.2018.
The NEFTECOR coating system has the decision  of  All-union Pipeline Construction Scientific and  Research Institute, FGUP State Research Institute of Civil Aviation.
The coating system is  included in the  TD  “Technical Requirements for Protective Coatings” of Mondi  Syktyvkar Forest-Industry Complex, JSC.

Surface preparation

• degrease the metal surface to 1 grade according to GOST 9.402;
• clean  the surface with abrasive blasting from scale and corrosion products to a degree no t  lower  than  2  according to GOST 9.402 (not lower than  Sa  2  ½ according to ISO  8501-1) with an angular, sharp  surface profile.
• remove the dust from the surface.

Reducing the  surface cleaning  degree and deposition on a  smooth surface without  roughening is not  allowed.
Before applying the second layer  and  before applying the NEFTECOR  enamel, the coating should be  dry, clean and free of oil and dust.

Application 

• mix the base to a homogeneous condition before application;
• add a hardener to the enamel base with constant stirring and mix thoroughly. 

Mass ratio of the base: hardener:
‒ for orange color 100:19 hardener EN-05;
‒ for gray color 100:13,3 hardener EN-14;

• dilute to the working viscosity, if required.

When organizing painting work, it is necessary to take into account the decrease of the  pot  life  of  working mixture (after mixing the components) with increasing temperature.
The material is recommended to be applied in the factory and field conditions:

• orange color at a temperature of plus 5 to plus 35 °C and relative air humidity no more than 85 %;
• gray color at temperatures from minus 5 to plus 35 °C and relative air humidity no more than 85%.

The temperature of the surface to be painted must be at least 3 °C above the dew point. The primer prepared for application must have a temperature of at least plus 15 °C. It is recommended to apply 1-2 layers by airless spray, brush/roller.

Storage and handling

The  material  is delivered in packages:  the  base and hardener packed in metal buckets and metal  cans respectively depending on the set weight.
Storage conditions  –  according to  GOST 9980.5 (at air temperature from minus 40 to plus 35  °C).  The  container  with the material  components  shall be stored away from heat sources,  protected from  atmospheric condensation and direct sunlight.
The shelf life  is determined by warranty storage  of the base  (24  months) and hardener (specified in  quality certificate) starting with the manufacture date.

Precautions

When working with the  primer,  one shall observe the existing sectoral standard norms and  requirements and safety measures as specified on the package label.
Personal protective equipment (goggles, face masks and respirators) shall be used, 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 material and its components (base and hardener) are classified as fire-hazardous materials!

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.
