VINICOR®-marine primer

Description

The high solids epoxy primer can be used in thick coating systems, supplied in two packs. Nonsensitive to surface treatment, can be applied on solid corrosion and/or old coating products.
The coating is resistant to the impact of sea and fresh water, oil, petroleum products, and other media, rapid temperature changes from -50°C to +60°С.

Recommended use 

Protection against corrosion of underwater and above-water hull parts, strake, variable water lines and superstructures of the ships of unrestricted navigation area, and any other structures operated in sea and fresh water and atmospheric conditions.
Suitable for carbon and stainless steels, fiberglass and carbon fiber, aluminum and concrete.

Used as:

• Independent coating
  
• Priming layer in complex coating systems with VINIСOR-marine, VINIСOR-62, POLYTON-UR (UF) enamels, VINIСOR, VINIСOR-acryl-51, VINIСOR-nord enamel primers, and other enamels and enamel primers on vinyl-epoxy, epoxy-urethane, epoxy, acrylate and polyurethane bases.
  
• As a tie (adhesive) layer for underwater hull parts and variable water line area between an epoxy coating and antifouling enamel.
  

During operation in the atmosphere at intensive UF radiation, chalking is common for the coating like for any other epoxy material.

Surface preparation

Carbon steel surfaces

• Degrease the metal surface to the first degree according to GOST 9.402
• Blast clean from scale, rust and old paint traces to degree 2 per GOST 9.402 (Sa 2 ½ or Sa 2 per ISO 8501-1); in case of painting repair, can be cleaned from rust mechanically to degree 3 or 4 minimum as per GOST 9.402 (Sa 2 or St 2 as per ISО 8501-1).
• Dedust.

Aluminum and stainless steel surfaces:

• Degrease the metal surface to the first degree according to GOST 9.402
• Blast clean by non-metal grinding agent that provides a surface with a sharp profile. Alternatively, grind the surface manually or mechanically by non-metal grinding agents or sandpaper
• Dedust.

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

• Degrease the surface to degree 1 as per GOST 9.402
• Clean the surface from drips, pitch streaks, adhered fibers, reinforcing glass cloth by grinding
• Dedust.

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%.
Before applying the second layer and before applying the top coat, the coating shall be dry, clean and free from oil and dust.

Application 

• mix the base thoroughly to homogenous condition before application;
• with constant stirring, add the  hardener to the base and mix thoroughly  (the ratio of the base and hardener stated on the label of the package and in the material quality certificate);
• dilute to working viscosity, if required;
• before application, the prepared material shall be held for 15-20 minutes covered.

When working, one shall consider decrease in  pot  life  of the composition (after mixing the components) at air temperature increase.
The material is recommended to be applied in the plant and field conditions at temperature from plus 5 to plus 35 °C and relative air humidity not more than 85 % (application at temperature from minus 5 °C is allowed). The temperature of the painted surface shall be above the dew point by at least 3 °C.
Prepared primer shall be of temperature at least 15 °C.
The primer is recommended to be applied in 1-2 layers using airless, air spray, by brush/roller.

The above-mentioned hardening time shall be assumed as a guideline (the hardening time depends on surface and ambient air temperatures, material dilution ratio, coating thickness, ventilation efficiency and relative air humidity), the actual time shall be determined experimentally, when painting in specific conditions.

The maximum overcoating interval for VINIСOR-marine primer is 6 months. If the maximum overcoating interval is exceeded, the coating shall be roughened by light blasting or mechanical tool, before the next layer can be applied.

Storage and handling

The material is supplied complete: base and hardener packed in metal buckets and metal cans, respectively, depending on the weight of the kit.
Storage conditions shall be in accordance with GOST 9980.5 (at ambient temperatures -40°C to +35°C). During storage, protect containers with material components from heat, precipitation and direct sunlight.
The guaranteed shelf life is determined by guaranteed shelf life of the base (24 months) and hardener (12 months) from the date of manufacture.

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.
