DynaSeal sealer, commercially launched by BASF in late 2001, is a finalist in the 2002 Premier Automotive Suppliers' Contributions to Excellence (PACE) Awards for Product Innovations.
DynaSeal is a dual-cure (UV and thermal) sealer for coating sheet molded composite (SMC) materials used in automotive applications, enabling BASF to participate in this high growth area. SMC is extensively used in automotive applications because of its favorable weight-to-strength ratio and ability to be molded into complex parts. However, SMC has been difficult to paint with standard automotive coating systems due to ""out-gassing"" of volatile materials from the substrate during the curing process. This situation, known as ""porosity,"" usually causes high repair rates at molders and automotive assembly plants. As such, SMC's viability for use in exterior class A body panels was limited prior to BASF's commercial launch of DynaSeal sealer.
""DynaSeal prevents porosity defects in automotive coating layers by sealing the SMC surface,"" explained Ray Nix, Director, Sales and Services, Automotive Components for BASF Corporation's Coatings Regional Business Unit. ""This is achieved by curing the sealer with an ultraviolet (UV) light followed by a thermal cure, which delivers the necessary performance properties for coatings like adhesion and stone chip resistance. Using this new technology allows the SMC surface to be sealed by the UV-induced polymerization before the part experiences any heat. The UV-polymerized film prevents 'out-gassing' from the part when the subsequent paint layers are cured.""
