Top Coats for Enhanced Protection
ZPN NANO CLEAR & ZPN NANO BLACK – advanced nano-ceramic topcoats offering exceptional scratch resistance, stability under high temperatures, and suitability for small parts and screws.

PSSPL proudly participated in the India Fastener Show 2025
At the event, we presented our comprehensive portfolio of coating technologies, designed to deliver superior corrosion resistance, reliability, and eco-friendly performance. Our star highlights included:
ZN-FE-100 (Alkaline Zinc Iron)
ZPN 100 T & 150 G (Alkaline Zinc Nickel)
Cyanide-free alkaline Zn-Ni electrolytes for barrel and rack plating, with 10–15% nickel content. Renowned for excellent corrosion resistance, especially in heat-treated parts, and superior efficiency post-aging.
ZPN 700 (Acid Zinc Nickel)
An acidic electrolyte for zinc-nickel alloy plating with consistent alloy composition, optimized for both barrel and rack plating, ensuring stable corrosion protection.
