ECOZIN 96% zinc-rich primer — polyorganosiloxane cold galvanising
ECOZIN 96% is a CERTA polyorganosiloxane zinc-rich primer whose dry film contains 96 % zinc. It protects chimneys and flue gas stacks, steel structures of industrial buildings, power line and overhead contact line supports, road safety barriers and hydraulic structures, and works from −60 °C to +350 °C, and in a system with CERTA silver enamel up to +600 °C. The predicted service life in an industrial atmosphere of temperate and cold climates is at least 10 years; it is applied from −10 °C.
