Powder Coating Primer Containing Zinc - China

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.

Qualisteelcoat approval: Base Material: Steel PE-0097 2 coat system – up to C4-H, mechanical pretreatment.
