KO-8111 CERTA — heat-resistant primer-enamel up to +700 °C for pipelines
Pipelines — steam, heat, product and oil pipelines — as well as chimneys and steel structures exposed to oils, petroleum products and salts are the main field of KO-8111. The primer-enamel works from −60 °C to +700 °C depending on colour, is manufactured to TU 2312-014-49248846-2010 and requires no priming. For service above 100 °C, the coating undergoes hot curing at commissioning; intercoat drying at +20 °C is 30 min.
