Product Description
MT-PZ is a powder coating primer containing zinc which is designed to give enhanced corrosion protection of mild steel. This duplex system combines cathodic protection and barrier effect. Dedicated to steel protection with a surface pre-treatment obtained by grit/shot blasting. MT-PZ is based on a specific epoxy zinc rich formulation that brings conductivity to enable the cathodic protection. MT- PZ includes a specific anticorrosive function which improves the protection in case of scratch.
