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.""
Australian organisations Austrak, Laing O’Rourke and the University of Southern Queensland (USQ) have joined forces to develop polymer composite solutions for bridge transoms in a $10 million project titled Polymer Composite Transoms for Rail Bridge Deck Replacement (CompTrans).
Composites One and the Closed Mold Alliance, along with more than 15 industry partners, will demonstrate the latest advancements in closed moulding and advanced processes for building real-life parts for marine, aerospace and other markets during CAMX 2018 in Dallas, Texas, US, on 16-18 October.
With its new ‘Process Live’ format, processing and manufacturing processes will become a visible focus of this year's Composites Europe exhibition in Stuttgart, Germany, on 6-8 November. Mechanical and plant engineering companies will get together in group exhibits to showcase their technologies in live interactions, enabling visitors to experience sub-processes in a larger context.
