Insulating polymeric coating ASTRATEK metal

pic Heat-insulating polymer coating ASTRATEK metal for metal surfaces.

The liquid thermal insulator ASTRATEK metal is a special composition with improved corrosion resistance and adhesion for thermal insulation of metal objects and structures, which are operating in conditions of a really high humidity and an impact of slightly aggressive fluids.

The insulation coating is characterized by high and stable adhesion, weather resistance, heat resistance (up to 260 °C), anti-corrosion properties.

The liquid thermal insulator ASTRATEK metal is a specially designed multifunctional coating that solves the problem of thermal insulation and protection against condensation and corrosion.

ASTRATEK metal is made for thermal insulation and corrosion protection for ferrous and non-ferrous metals: pipelines, industrial equipment, containers for various purposes, as well as for concrete structures. Operating mode is from -60 to +200 °C (with a maximum peak load of 260 °C for 1-2 hours).

Thermal insulation polymer coatings ASTRATEK metal shall be applied in layers. The thickness of the put liquid insulation ASTRATEK layer should be about 0.4 mm. The rate of the material consumption for a single-layer coating (0.4 mm) is about 1 liter per 1.5 - 2 square meters. The complexity of an application is similar to the complexity of any painting works. The service life of the polymeric coating ASTRATEK is 15 - 25 years (depending on operating conditions).

The manufacturer of the liquid insulation ensures a consistent quality of the material at least for a one year during its transportation and storage under appropriate conditions.

Hazard category (as a chemical composition) for ASTRATEK is 4 (GOST 12.1.007-76). The material may be considered as a safe load for transportation.

Thermal insulation polymer coatings ASTRATEK (metal) are available in a cold-resistant version. The material marked "frost resistant" can be transported and stored at temperatures up to -40 °C for a month with allowed up to 5 cycles of freezing.

Benefits of Astratek (metal) composition:

• reduces or eliminates the formation of condensate

• temperature resistant up to + 260 °C*

• prevents corrosion under the insulation cover

• protects personnel from burns

• may be applied on surfaces of any configurations

• provides a permanent access for inspection of insulated surfaces

• does not support a combustion, reduces the spread of fire and smoke formation

• non-toxic, environmentally safe

• low labor and resource consumption during operation and repair slightly aggressive media

• resistance to slightly aggressive fluids

• allows to insulate objects without stopping the technological cycle

* There are restrictions, check it with technicians of the manufacturer
