Tsinkonol — one-component zinc-rich polyurethane primer

Zinc-rich primers

Tsinkonol is a one-component compound for “cold galvanising”: zinc powder is dispersed in a solution of a polyurethane prepolymer, and the coating cures with atmospheric moisture. It is used on steel structures, bridges, pipelines, tanks, oil and gas facilities, marine structures and equipment, as well as for restoring hot-dip galvanised surfaces. The material works on its own or serves as a primer under the Poliuretol UV and Epostat enamels and allows welding through the coat; with polyurethane enamels the system lasts up to 25 years in temperate and cold climates.
