Dow Chemical has signed on as a global Olympic sponsor through 2020.
The International Olympic Committee announced Friday that the American giant had become the official "chemistry company" for the games, a new category.
The deal covers the 2012 London Olympics; 2014 Winter Games in Sochi, Russia; 2016 Summer Games in Rio de Janeiro, as well as the 2018 Winter Games and 2020 Summer Olympics.
IOC president Jacques Rogge says Dow "will not only provide critical financial support to the Olympic Movement, but also bring industry-leading expertise and innovation to the Games themselves."
Dow becomes the 10th global sponsor for the London Games.
The impending deal with Dow was first reported by The Associated Press last month.
