ALPOL® anticorrosive composition

Description

Single-packed  composition  based  on  high molecular weight synthetic polymer and aluminum powder.

Recommended use 

Anticorrosive protection of steel articles and structures operated in the atmospheric conditions of all macroclimate areas, types of atmosphere and placement categories according to GOST 15150. The composition is used on zinc-rich coatings ZINOL and ZINOL-SV (TU 2313-012-12288779-99) as a protective and decorative layer (application in 1-2 layers).
The ALPOL coating is not stable in gasoline and a number of organic thinners.

Surface preparation

Primer coating ZINOL (ZINOL-SV) must be cleaned from dust and dirt, degreased with aqueous solutions using detergents (pH of the solution in the range of 6 to 8) and dried. Do not use solvents for degreasing!

Application

• mix the composition thoroughly to homogenous condition before application;
• if necessary, dilute to working viscosity immediately before application;
• during work, the composition should be mixed intermittently.

Apply in factory and field conditions at temperature of minus 25 °С up to plus 40 °С and relative humidity up to 85 %. ALPOL composition should be  applied on the ZINOL or ZINOL-SV primer  coating  after it has dried, but not earlier than 2 hours after its application.
When applying multilayer coatings, each subsequent application should be applied after the previous one has dried to "tack"  (slight touch on the coating does not leave a trace and does not give a feeling of stickiness).

Drying of the coating is natural. The time for complete hardening of the coating and holding time before the start of operation in severe atmosphere  is at least 7 days, before the beginning of packaging and transportation - 24 hours.

Storage and handling

The composition is delivered in packages: in metal buckets or metal cans.
Storage  and transportation  conditions  of composition  –  according to  GOST 9980.5 (at air temperature from minus 40  °C  to plus 40 °C). The  container with composition  shall be  protected from direct sunlight and atmospheric condensation. It is allowed to store containers with a composition for short periods in direct sunlight, but not more than 3 hours.
In case of storage at low temperatures before application, the composition should be kept in warm for a day.
The shelf life of the in hermetically enclosed original container is 24 months  starting with the manufacture date.

Precautions

When working with the composition,  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 composition 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.
