   The company was founded in 1883 in Pittsburgh (USA) and now includes over 150 production units and offices in more than 60 countries which employ 40 thousand people. In 2011 the company’s sales reached $14.9 billion PPG Protective & Marine Coatings (PPG PMC) is a part of the PPG Industries Inc. with headquarters in Amsterdam. PMC is the cradle of recognized worldwide coating brands, including AMERCOAT® and SIGMA COATINGS®.PPG PMC offers optimum coating systems for protection that lasts decades, is resistant to extremely low/high operating temperature, temperature fluctuations, high UV radiation and humidity, exposure to chemicals and mechanical impact.

   In Russia, PPG PMC strives to solve the most challenging tasks of the clients related to protection of any surfaces in extreme climates. As a leader in development of new products, PPG creates opportunities for extending the life of coating, retaining its properties in cold, high humidity climates or under mechanical/abrasive load. This ensures that our clients, who use the most effective solutions in the world, are confident in durable protection of their structures.

   Protective coatings for cold climates are grouped depending on their purpose under the brand names SigmaCover, SigmaDur, PSX 700, PittChar XP, SigmaShield, SigmaGuard, SigmaZinc:
The combination of all-purpose advanced technology and know-how ensures comprehensive and cost-efficient solutions to the challenge of protecting structures in cold climates.
PPG coatings are particularly successful in Russia due to the following innovative technologies:
Curing of epoxy coatings at low temperatures and high humidity.
In the early 1980s PPG experts were the first in the world to develop a unique composition of flexible and reactive epoxy-ether resins that enable curing of epoxy coatings at temperatures down to -10 C. The coatings have unlimited overlap time, too – this is always important for long-term projects.

   Later, PPG introduced the phenalkalamine-based curing technology lowering the cure temperature for epoxy coatings even further, down to -18 C. Usage of the new-generation materials in cold temperatures ensure high adhesion to metal, sufficient curing speed for polymer resin and hardener. Also, the coating can be applied at a higher humidity (>85 percent) without “sweating out” of the cure ingredient.

   For the past seven years, these technologies are widely used in Russia at oil and gas facilities of LUKOIL, Total, in bridges and hydraulic structures, concrete structures, pipelines.

   Providing coating systems for cold-resistant protection of structures and taking into account the special climate in Russia, PPG confirms the that anti-corrosion properties of its coatings valid for operation down to -90 C, including temperature spikes.

   One of the technology know-how is a unique flame retardant epoxy coating PittChar XP® – the material retains 5 percent flexibility at -40 C, keeping its fire retardant properties even a dip in liquid nitrogen at -186 C. Coating flexibility at low temperatures (down to -90 C) weakens the internal stresses from temperature spikes, vibrations of metal structures and mechanical effects. Ultimately, the PittChar XP® coating achieves the ultimate goal – retaining for decades the integrity of the coating and load-bearing structures regardless of extreme weather conditions, vibration or mechanical stress. This ensures maximum efficiency of the coating in the event of emergency.

   In Russia, this technology was introduced in 2010 and gained recognition at LUKOIL and Dragon Oil facilities in Astrakhan.

   One of the challenges that the market faces is to protect structures from the surface ice. The task is to find answers to two fundamental questions – how to use coatings to reduce the formation of surface ice and, if it is formed, how to remove it easy without damaging the surface.

   Studies conducted by the American Military Institute show that PPG product PSX 700 is the only market entry with much lower friction ratio with the ice, which ensures its easy removal from the surface. PSX 700 – a product developed from the ground up on the basis of innovative epoxy-polysiloxane technology – has been included in the industry roster for the US military as a coating for strategic facilities. In Russia, the product is actively used since 2007.

   SigmaShield products specifically designed for facilities operating in cold climates of Russia, with high mechanical/abrasion loads such as ice, sand, gravel. Products combine maximum abrasion and chemical resistance, faster drying, 100 percent dry residue, ease of application for the single coat up to 1,000 mm thick, integrity of the coating in cold conditions and temperature extremes.

   Cutting-edge technologies of PPG offer an ultimate opportunity to protect the client’s structures in extremely cold climate.
