SK-MET — polyurethane enamel for C5-I and C5-M category systems
Polyurethane RAL enamel for steel structures and bridges, withstands +150 °C in a dry environment, finish of C5-I and C5-M systems per ISO 12944.

A primer of the SNEZH-PRO series based on a modified alkyd varnish with a drier; its main purpose is the bodies and underframe equipment of railway rolling stock, transport structures and other metal surfaces, and it has also been used for cranes. It is applied by spraying in 1–2 coats, the wet-on-wet scheme is permitted, and at 60 °C it dries to degree 3 in 0.25–0.5 h. Paired with the SNEZH-PRO 111MU enamel the primer forms a system for UKhL1 and KhL1 climates with a service life of 8 years.
