Dulux Autospeed Flex Additive is one of a range of ancillary products developed for automotive refinishing. It is to be used as an additive for 2K coatings for flexible substrates such as bumper bars and spoilers. As the Flex additive has its own catalyst requirement, the overall level of catalyst in the 2K system will need to be adjusted. Dulux Autospeed Flex Additive is not required in the 440 or 480 line product range. Refer to the respective TDS for addition recommendations to the various systems in the Dulux Autospeed range.
