The automotive industry demands for quality and technological innovations that enhance the performance of their products. Visual quality and corrosion resistance are also very important, even for fasteners exposed to the weathering throughout its life cycle that shall meet the performance requirements specified by the automotive industry.
This paper shows how the search for new technologies leads to innovations in the already established surface treatment with a new generation of sealers for the automotive industry.
This brand new technology of organic/polymeric sealer applies in water basis a single and uniform layer with low molecular weight (1000 to 10000 Dalton) in order to enhance specific properties such as high corrosion resistance, low coefficient of friction attributing characteristics of self-lubricating surface and increase in the wear resistance of the coating.
Besides technical requirements, the visual aspect of a fastener makes a difference in the competitive automotive market, which mainly depends on the coating of the fasteners.
