CERTA heat-resistant anticorrosion enamel — silicone enamel up to +1,200 °C

Heat-resistant coatings

CERTA enamel on silicone resins withstands from −60 °C to +1,200 °C depending on colour and is applied at temperatures from −30 °C. It is used on gas pipelines, steam pipelines, industrial chimneys, power line towers, communication masts, boiler and heat exchange equipment; for bridges and overpasses, its use is provided for by the STO of AO TsNIITS. The predicted service life under UKhL1 conditions is up to 20 years; the enamel is included in the Register of Russian Industrial Products and serves as a topcoat over ECOZIN primers.
