PN-6 High Corrosion Resistance Water Soluble Sealant
PN-6 is an environmentally friendly, hexavalent chromium-free sealant designed for superior corrosion protection on zinc-plated surfaces.
Key Properties
- Environmentally friendly formulation without hexavalent chromium
- Ideal for sealing after various zinc plating passivation processes, typically resulting in a silver appearance
- Suitable for both immersion and spray application methods
- Enhances protective performance of passivation films by 0.2-0.5 times in neutral salt spray tests
