Powder coating primer containing zinc
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.

Application
MT-PZ is suitable for corona electrostatic spraying. Tribo application is not recommended.
| Application settings | Fluidizing air pressure: 1.5kg/cm2 initially then 1kg/cm2
Transport air pressure: 0.5 to 0.8 kg/cm Recommended voltage: 65 to 70kV |
| Curing limits | Primer should be cured, or at least gelled, using the recommended curing schedules, before application of the topcoat. The object temperature must not be below 110°C or above 180°C.
The primer should be cured in a convection oven, optionally with infra-red heaters, with air temperature not exceeding 180°C. |
| Recommended film thickness | 70-120 µm A good protection is linked with the recommended film thickness. |
| Recycling | Trials, with suitable recycling equipment, must be carried out before commencing production. Attention should be paid to the ratio of new powder, a minimum of 70% must be used. Gun nozzles must be cleaned every 30 minutes. |
