Mid phosphorus electroless nickel process

Berlin, June 2017: Atotech is pleased to introduce Nichem® MP 1188, a fully bright, ELV, RoHS and WEEE compliant mid phosphorus electroless nickel process capable of standing up to the highest production demands, but also with the flexibility required to accommodate a range of surface areas and multiple substrates – all in one process.

The modern demands of an electroless nickel plating operation are high, and the applications range from high production volume automotive to lower volume job shops. Mid phosphorus coatings not only need to offer good corrosion protection. They also need to be bright and provide low tensile stress, long bath life and be tolerant to contamination. To fulfill all the requirements typically meant choosing an electroless nickel process specifically suited to a particular application – with Nichem® MP 1188 not anymore.

Nichem® MP 1188 with its excellent bath stability and corrosion protection is formulated to be very tolerant to extremely low bath loading. The new process has shown outstanding self-initiation ability on copper and its alloys making it a versatile process for handling a wide variety of substrates. Production shows that the process has a high tolerance to zinc contamination, thus making direct plating on to zincated aluminum alloys throughout bath life possible without sacrificing brightness and adhesion.

“Nichem® MP 1188 is a truly environmentally friendly process as it’s free of lead and cadmium”, states Shakeel Akhtar, Global Product Manager for electroless nickel at Atotech. “This makes our latest electroless nickel process a perfect complement in Atotech’s portfolio of sustainable plating solutions.”

Nichem® MP 1188 offers nickel-phosphorus coatings with a 5 – 8% phosphorus content resulting in “as plated” hardness in the range 550 – 560 HV0.1. The versatile and stable process has a wide operation window and provides consistent brightness over the whole bath life. Nichem® MP 1188 is suitable for a wide variety of applications in various industries such as agriculture, automotive, consumer electronics, connectors, oil and gas and even wind energy.
