GM approves corrosion protection system

WEST HAVEN, Connecticut, USA – Enthone is proud to announce the approval of the company’s Perma SHIELD? 1000 zinc-nickel system by General Motors to meet the GMW4700 Zinc Nickel Type B requirement. The approval was granted for the following processes:

> ZINCROLYTE? KLC-NI ammonia-free, acid zinc-nickel;

> PERMA PASS? Ultra IV Plus low temperature, transparent passivate; and

> ENSEAL? 1303 sealant specially formulated to meet automotive requirements. 

The Perma SHIELD? 1000 system provides superior corrosion protection to red rust, while also demonstrating exceptional performance to white corrosion. Applicators have achieved substantial productivity gains as a result of dramatically reduced plating times on high hardness parts due to the system’s exceptional initiation and efficiency. 

All Perma Shield 1000 systems create value throughout the entire supply chain and feature the company’s patented Zincrolyte acid or alkaline zinc-nickel process production-proven to extend product life, increase yields and reduce rejects. Each process is followed by a Perma Pass passivate and an optional Enseal sealant.
