It was under this area where he developed and first demonstrated the 100 % solids polyurea spray elastomer technology. In 1987 he joined the Performance Polymers Group where he has been involved in polyurea RIM and spray elastomer development and applications development of amine catalyst in polyurethane foam systems.

In 1994, Dudley became part of Huntsman Corporation following the sale of Texaco Chemical Company. Here, he was a Research Chemist in the Thermoset Applications Group devoting his efforts to marketing and applications development of the polyurea spray elastomer technology.
