On the way to gold medals at Rio with LANXESS

Jump to the comments
Cologne - Inorganic pigments from specialty chemicals company LANXESS have added color to many major sporting events in the past. Now the products from the successful Bayferrox range are to do the same for the Sports Park in Barra da Tijuca, Brazil. “From August 5 to 21, 2016, when 10,000 athletes from 166 countries compete in 28 sporting events at the summer games in Rio, both the participants and spectators will literally be walking on LANXESS,” says Jörg Hellwig, head of the LANXESS Inorganic Pigments business unit. That’s because much of the area around the venues is colored with black and red pigments from LANXESS.
 
Premium pigments for design and safety
 
The "Olympic Way", a boulevard of black and light gray concrete paving stones, meanders along the entire stretch from the entrance, past the 15 venues, to the tip of the triangular grounds. The eight-centimeter-thick stones, placed in a wave shape, symbolize the confluence of the Rio Negro and Rio Solimões (Amazon River). The black-water Rio Negro gets its dark coloring form its high content of humic and fulvic acids, while the white-water Rio Solimões looks white when viewed at an angle on account of the mineral-based solids suspended in it. The rivers flow adjacent to one another over a distance of 11 kilometers before eventually converging. The concrete paving stones symbolizing this “Meeting of the Waters” were manufactured with over 40 metric tons of the iron oxide black pigments Bayferrox 318 and Bayferrox 340.
 
Numerous quiet zones around the venues are also of colored design, as is the large square in front of the public viewing park right off the boulevard. Their prominent red coloring comes from Bayferrox pigments. Drainage stones measuring 40x40x8 centimeters and colored with over 20 metric tons of Bayferrox 110 have been laid over more than 12,000 square meters of the park. These highly water-permeable paving stones prevent puddles from forming after heavy rainfall.
