A new generation of automotive refinish products - new sealers, primers and clear coats, reinforced with newly invented bio-based polymers, are to be tougher and chip-resistant. These new product from DuPont could be available for use in auto collision repair centers by 2008 and are to be manufactured with renewably sourced intermediate ingredients that are biodegradable and virtually non-toxic. The renewably sourced polymer content of the new finishes will enable them to last longer and better resist stone impact.
The bio-based polymers to be used in the new finishes are based, in part, on the science used by DuPont to create 1,3 propanediol (PDO). PDO will be produced in a plant now being built in Tennessee by DuPont and its joint venture partner, Tate & Lyle. The Bio-PDOTM process consumes 40% less energy than its petrochemical counterpart.
