VM-8352N — epoxy powder for the second layer of factory pipe coating
Powder material for pipe plants, sprayed as a second layer over uncured VM-6233R onto a heated pipe.

A two-pack epoxy primer-enamel with corrosion inhibitors, included in GOST 7409-2018. Its main field of application is freight wagons outside and inside, including for non-food bulk cargoes and mineral fertilisers, railway infrastructure (except railway bridges) and other steel structures in aggressive environments. It is applied over tightly adhering rust and old coatings at temperatures from −10 °C; it works on its own or is overcoated with VINIKOR-62, POLITON-UR (UV), VINIKOR-akril-51 and other enamels.
