ISOLEP®-235 primer/finish

Description

ISOLEP-235 is a two component polyamine cured modified epoxy coating with high solids. It is a surface tolerant, allows application on surfaces after water jet cleaning. It can be cured even at freezing temperatures.

Recommended use

Protection of the inner surface ballast tanks and compartments filled with seawater, decks, erections, freeboard and ship’s bottom. It can be used to protect metal structures of improvement works in sea and fresh water, in areas of full immersion and at a running level, in atmospheric conditions. Provides long-term protection in environments with high corrosivity, resistant to spills of mineral oils, crude oil and petroleum products, propylene glycol, coolants, freon (in the form of gas), household waste withstands abrasion wear and impact loads.

Can be used for pressure vessels.

It is used (for carbon, galvanized, stainless steels, non-ferrous metals and alloys) as a single coat
system, as well as in coat systems with VMP materials: shop-primers  ZFES-sp, ISOLEP-eps, ISOLEP-SP-03 and with top coats POLYTON-UR (UV), VINICOR-marine, VINICOR-acryl, ISOLEP-epoline, as well as with other coatings as agreed with VMP.

Surface preparation

New steel surfaces:

• degrease the metal surface to the first degree according to GOST 9.402;
• abrasive blasting from scale, rust to degree 2 according to GOST 9.402 (to Sa 2 ½ ISO 8501-1) with a sharp-edged surface profile with roughness 30-75 μm (ISO 8503-2); on hard-to-reach surface areas, cleaning to Sa 2 or St 3 (ISO 8501-1).

For temporary protection of metal structures, if necessary, use a shop-primer.
Before applying the main coating, the shop-primer coating must be cleaned of grease and other contaminants, the dust must be removed, damaged areas must be cleaned and repaired by ISOLEP-235.

Repair and maintenance:

• degrease the metal surface to the first degree according to GOST 9.402;
• remove salts by high pressure fresh water cleaning;
• clean damaged areas by power tool cleaning from rust to St 2 (ISO 8501-1) or by abrasive blasting to Sa 2-Sa 2 ½ (ISO 8501-1) for improvement performance characteristics of the coating.
• remove dust.

It is allowed to clean by high pressure water jetting (pressurized to above 70 MPa) to Wa 2 and flash rust grade not lower than M (ISO 8501-4).

Painted surfaces:

Remove from the surface in an appropriate manner salts, oils and other contaminants that impair the interlayer adhesion of coatings. Allow to dry and remove dust. Eliminate coating defects. Pay attention to the interlayer exposure of the coating.

Galvanized steel:

• in the presence of zinc corrosion products on the surface to remove them by water jetting (pressur-ized to above 34 MPa) or to clean surface with a hard synthetic brush by low pressure water jetting (if neces-sary);
• degrease to the first degree according to GOST 9.402;
• clean by power tool cleaning or by light abrasive blasting with fine non-metallic abrasive (quartz sand);
• remove dust.

Aluminum and stainless steel

• degrease to the first degree according to GOST 9.402;
• clean by power tool cleaning or by light abrasive blasting with fine non-metallic abrasive (quartz sand);
• remove dust.

Application

• before use, mix the base of ISOLEP-235 until smooth;

• with constant stirring, add curing agent to the base, mix thoroughly; if necessary dilute to working viscosity.

The pot life of ISOLEP-235 (after mixing the components) at an ambient temperature of (20±2)°C is at least 2 hours (when organizing painting work, a decrease in viability with increasing temperature should be taken into account)

ISOLEP-235 is recommended to be applied at an ambient temperature of minus 10 to plus 40 °C and relative air humidity up to 85 %. The temperature of the surface to be painted should be at least 3 °C above the dew point.

When painting at low temperatures, the temperature of ISOLEP-235 itself should not be lower plus 15 °C.

The maximum overlapping interval depends on the operating conditions:

- when immersed in water (or high humidity) to the next layer of ISOLEP-235 – 21 days, to the top coat – 7 days;

- in an open atmosphere – 6 months.

If it is exceeded, the surface should be roughened using light abrasive blasting (sweeping), mecha-nized or hand tools.

Storage and handling

ISOLEP-235 is supplied as base in 20 litre and curing agent in 5 litre metal containers respectively, depending on the weight of the complete set.

Storage conditions – according to GOST 9980.5 (at air temperature from minus 40 to plus 40 °C). The components shall be stored away from heat sources, the container shall be protected from direct sunlight (short-term exposure, not more than 3 hours, is allowed) and atmospheric condensation.

The shelf life of the base is 24 months, the curing agent - 12 months starting with 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.

ISOLEP-235 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
