TSVES-MO — zinc silicate primer for hot surfaces up to +400 °C
Moisture-curing zinc silicate primer for furnaces, boilers and heated pipelines, including those operating under thermal insulation.

Unlike the basic TSINEP, this primer contains at least 80 % metallic zinc in the coating, which corresponds to level 2, type II per SSPC Paint 20. It is used only as a primer coat in systems for steel structures, bridges, chemical plants, marine and port structures. It is overcoated with IZOLEP-mio, POLITON-UR, POLITON-UR (UV), ALUMOTAN and epoxy, polyurethane and acrylic based enamels, and is suitable under PLAMCOR fire protection. The coating is resistant to fresh and sea water, salt solutions and petroleum products.
