immediately became one of the world s leading producers of titanium dioxide pigments . production capacity for these specialties increased by a further 100 000 t a to 340 000 t a with the acquisition in 2012 2 of the facilities of the insolvent crenox gmbh competitor a former bayer subsidiary in krefeld . rockwood holdings inc. acquired kemira s stake in the joint venture in early 2013 .

white paint base on a zinc sulfide barium sulfate basis . the fledgling company achieved success against competing products only after numerous technical and chemical problems had been overcome a process in which the young chemist rudolf sachtleben played a decisive role . lithopone the world s first genuinely durable white paint base then quickly began to replace the toxic white lead previously used . rudolf sachtleben took over management of the company in 1883 becoming a partner in sachtleben & co. lithopone fabrik sachtleben & co. lithopone manufactory in sch ningen . the success of the new product coupled with low cost recovery of zinc by means of chlorinating roasting of iron pyrites from meggen in germany s hilly sauerland region paved the way for rapid expansion . sachtleben & co. lithopone fabrik thus relocated to duisburg in 1892 since the rhine and the nearby ruhr industrial region even then offered optimum locational conditions in terms of labor transportation and supplies of energy and water . by 1906 production had multiplied sixfold and a second production plant had been constructed . sachtleben its workforce and its facilities also suffered from the effects of inflation and the global economic crises during the first world war the immediate post war period and the subsequent occupation of the ruhr by french and belgian troops in

million marks and registered offices in cologne . production of lithopone grew significantly up to the outbreak of the second world war in 1939 while new technologies helped to greatly expand the range of products . lithopone was needed in germany during the second world war both for civil applications and for camouflage paints . production ground to a halt following severe air raids in 1944 however and could be restarted only in 1946 after the repair of war related damage . the superiority of the properties of titanium dioxide over those of lithopone in many applications became apparent as early as the mid 1950s . for this reason sachtleben and dupont de nemours of wilmington delaware usa started a joint venture pigment chemie gmbh in 1959 . planning and construction of a titanium dioxide and a sulfuric acid plant started in 1960 . sachtleben subsequently began producing titanium dioxide using the sulfate route process in duisburg in 1962 ; annual production of titanium dioxide reached 18 000 tonnes the following year and is now around 100 000 tonnes each at the duisburg and krefeld locations plus some 130 000 tonnes at pori in finland . in 1973 sachtleben took a strategic decision to enter the highly promising water treatment chemicals segment . the acquisition of ekokemi of ibbenb ren and thus a simultaneous and comprehensive expansion of the product portfolio in the field of water chemicals followed in 1996 . sachtleben then consolidated its position as one of central europe s leading flocculant producers with the start up of mitteldeutsche wasserchemie miwac ; central german water chemicals in 2000 . sachtleben s water chemicals division was hived off in the context of the joint venture between sachtleben and kemira oyj in 2008 since the relevant agreement
