ISOLEP®-hydro primer-enamel

Description

Primer-enamel based on modified epoxy resin, with a high dry residue. Double-packed, consists of a base and a polyamine hardener.
When applied to the metal provides excellent anticorrosive protection when operating in river and sea water. The coating is characterized by high abrasion resistance, impact resistance, resistance to salt solutions, oil and oil product spills, acids and alkalis. Can harden at low temperatures. Compatible with cathodic protection system.

Recommended use

Anticorrosive protection of marine and river hydraulic structures of general and special purpose, including port facilities. It is used as an independent coating in the zones of full immersion (underwater zone) and
intermittent immersion/moistening, as well as in a complex system with acrylurethane enamel POLYTON®-UR (UV) (TU 20.30.12-033-12288779-2018) – in the spray zone (above-water zone).

Surface preparation

• to degrease metal surface to 1 grade according to GOST 9.402;
• to do abrasive blast cleaning of scale, rust and traces of old paint to 2 grade according to GOST 9.402 (Sa 2 1/2 according to ISO 8501-1). Surface profile is sharp, angular with a roughnessof 85-115 µm (segment 3 of comparator G according to ISO 8503-1); when performing local repair of the coating, the degree of cleaning St 3 according to ISO 8501-1 is allowed.
• to remove dust.

Before applying coating enamels or before applying a second layer of primer-enamel, the primer coating ISOLEP-hydro must be decontaminated, degreased and dustless.

Application

• mix the primer-enamel base to a homogeneous condition before application;
• add a hardener to the primer base with constant stirring, mix thoroughly if necessary, dilute to working viscosity. Mixing ratio of base and hardener: by volume 4:1, by mass 6.5:1, respectively.

It is recommended to apply the material at ambient temperature from minus 5 to plus 30 °С (it is allowed to apply up to plus 40 °С) and relative air humidity up to 85 %. The temperature of the surface to be painted must be at least 3 °C above the dew point.
When painting in low-temperature conditions, the temperature of the primer enamel must be not lower than plus 15 °C, otherwise it may be necessary to add a thinner to achieve a working viscosity. It is also recommended to add the thinner at an air temperature of plus 30 up to plus 40 °C to reduce the likelihood of a “dry flare” effect and increase the working life of the material.

Storage and handling

The material is delivered in packages: base and hardener packed in metal buckets and metal cans respectively depending on the weight.
Storage conditions – in accordance with GOST 9980.5 (at air temperature from minus 40 to plus 40 °C). The material components shall be stored away from heat sources, the container shall be protected from direct sunlight and atmospheric condensation (short-term, not more than 3 hours, impact is acceptable) Shelf life of the primer-enamel is determined by the warranty period of storage of the base (24 months) and hardener (12 months) starting with the manufacture date.

Precautions

When working with the primer, the existing sectoral standard norms and requirements and safety measures as specified on the package label shall be observed.
Personal protective equipment (goggles, face masks and respirators) shall be used, and inhalation of thinners and contact of the primer with skin, ocular mucosa, respiratory channels shall be avoided; use inside the premises is allowed only in case sufficient ventilation is provided.
The primer is classified as a 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.
