Productivity of the overall repair job is of great importance. The productivity depends on many factors. These include: time between coats, time before sanding, and time before car can be reassembled and delivered. The demands for productivity are rising while VOC laws are becoming stricter. Now coatings must rely on low molecular weight materials, which require reactive cure. Unfortunately, increasing the cure via addition of catalysts causes an increase in the amount of solvent retained in the film. This lowers the Tg of the film and increases the time to sand. The interactions of solvent retention and cure will be discussed."@en . "Practical implications of solvent entrapment in ambient coatings" . "14"^^ . . "5"^^ . . "Congress Proceedings" . .
