Building on this original application, phosphonates have opened up a very broad spectrum of [...] addition, CUBLEN phosphonates are also used as setting retarders for concrete or gypsum. Textile and paper auxiliaries CUBLEN phosphonates are high-performance complexing agents. They are required in paper and pulp production to bind heavy metals and in this way increase the efficiency of bleaching baths. Furthermore, CUBLEN phosphonate complexing agents [...] Metal treatment CUBLEN phosphonates are ideally suited as additives for cleaning corroded metal surfaces. Both the acidic effect of phosphonic acids and their complexing character can accelerate the removal of rust, for example, and at the same time provide temporary corrosion protection for the cleaned surfaces. CUBLEN phosphonates are an environmentally
