Powder coating primer containing zinc MT-PZ ALZ55V
Product Description
MT-PZ is a powder coating primer containing zinc which is designed to give enhanced corrosion protection of blasted mild steel. This duplex system combines cathodic protection and barrier effect. Dedicated to steel protection with a surface pre-treatment obtained by grit/shot, MT-PZ is based on a specific epoxy zinc rich formulation that promotes conductivity to enhance its cathodic protection. MT-PZ includes a specific anticorrosive function which improves protection even in cases of scratching.
