The deal will see the DuPont logo on the nose cone of the new R3 car.
"Welcoming Dupont as a Jaguar Racing partner is a good boost for our team because of their complimentary values and outstanding reputation in material science," a spokeswoman for Jaguar said.
"This will help deliver many benefits to Jaguar Racing both on and off the track. We couldn't be happier about the fit and the mutual benefits we see in the relationship going forward."
Last week, Jaguar announced a sponsorship deal with technology company EDS, whose logo was displayed on the front wing of the R2 during last year's Japanese Grand Prix.
