Specialty chemical and coating supplier Enthone (West Haven, Connecticut) has announced General Motors' approval of its Perma Shield 1000 zinc-nickel system to meet the GMW4700 Zinc Nickel Type B requirement. The approval was granted for three processes making up the system, including Zincrolyte KLC-NI ammonia-free, acid zinc-nickel; Perma Pass Ultra IV Plus low-temperature, transparent passivate; and Enseal 1303 sealant formulated to meet automotive requirements.
The Perma Shield 1000 system provides protection against red rust as well as white corrosion. Applicators have achieved productivity gains as a result of reduced plating times on high-hardness parts with the system's initiation and efficiency.
