Organosilicate composition OS-12-03

Enamels for corrosion-resistant protection of metals and surfaces painting & decorating

 

OS-12-03
TU 2312-002-49248846-2002 with amendment 1, 2, 3

 

Weather resistant

 

OS-12-03 CERTA is used for protective and decorative coating of metal, concrete, reinforced-concrete, brick, plastered, ceramic surfaces, as well as inserts and reinforced-concrete fixtures operating in moisture-and weather environment, temperature drops from - 60把 up to +200把. It can be used in a wide range of temperatures: from - 30把 up to +30把.

 

Recommended to be applied by I. V. Grebenshchikov Institute of Silicate Chemistry of the Russian Academy of Sciences (St. Petersburg). According to the conclusion of State unitary enterprise "Research institute of constructing in Moscow" (GUP "NIIMosstroy"), predicted lifetime of OS-12-03 organosilicate composition coating is min. 8 to 10 years in the conditions of a moderate cold climate.
