Chrom VI – Chromate reduction

Chromate reduction for cement and dry mortar plants

At the end of the 1990s, a solution to cut the content of the highly toxic chromium resulted from cement manufacturing process was intensely sought. All existing methods against this harmful substance, arisen from the chromium-III-bonding, are flawed because they themselves pose many technical problems. The highly poisonous chromate is responsible for an occupational disease commonly known as ‘bricklayer-scabies’.

Stannous-II-sulfate is an optimal reducing agent for pathogenic chromate in cements. This unique characteristic is chemically justified. Unlike all other chromate reducers, the stannous-II-ion forms a water-insoluble complex together with the non-toxic chromium III ion which is created through the reduction process. Only through this reaction can we truly tackle the problem of the disease-causing chromate (Cr6+) at its roots. 

 

MIG specializes in chromate reduction and has developed an innovative tin sulfate system in which the content of tin has been successfully reduced. Our new chromate reducing agents based on tin-II-sulfate can save up to 50% stannous sulfate. While offering the same reduction capacity, price fluctuations of raw material can be compensated to the greatest possible extent. Naturally, this cost benefit will be passed onto our customers.

This shows that our new innovative chromate reducers are not only technically future-oriented but also highly economical.

A major new contribution to our product range is chromate reducer based on antimony-III-ions. These reducer systems are a good complement to our offerings.
