Economy and environment lie behind new PMD zincs

Environmental considerations, economy and ease of use are behind the launch of the new Zincobrite range of plating solutions from PMD Chemicals.

Environmental considerations, economy and ease of use are behind the launch of the new Zincobrite range of plating solutions from PMD Chemicals, part of the Coventry based PMD Group.

The new products cover the three groups of zinc plating: acid zinc (Zincobrite AZ, HT range), non-cyanide alkaline zinc (Zincobrite OH range) and cyanide zinc (Zincobrite CN range).

The Zincobrite AZ range base solutions contain no complexing agents or ammonia and the additives are VOC free.

The working solution gives mirror-brigh t levelled deposits.

Zincobrite HT has the added benefit of being suitable for high temperature operation up to 60 deg C without loss of brightness.

The Zincobrite OH range also contains no complexing agents leading to suitable effluent treatment.

Zero discharge can be achieved by the use of cascade rinsing and feeding the rinse water back to the zinc tank.

The Zincobrite CN range uses a concentrated brightener giving a low addition rate of only 40-60 mls per 1000 amp hours.

It is used in high, medium and low cyanide solutions giving excellent bright throwing power.

All the Zincobrite processes readily accept passivates.

PMD has just released a new range, including trivalent chromium products, under the Zincopass name.
