Literature
- Excellent porosity resistance to on galvanized plate.
- Significantly reduce surface porosity.
- Faster welding speed.
- The design of PRIMACORE® MC-200G enable to weld on thin galvanized plate with as much as 200g/m2 zinc coating.
- PRIMACORE® MC-200G can bring 50%-80% porosity issue improvement
