Dow Structural Adhesives Enhance Lightweight Module Construction

Dow Automotive Systems is leveraging its structural adhesives portfolio and development expertise to offer BETAFORCE, BETAMATE and BETASEAL solutions that enhance lightweight module construction.

Liftgate/hatchback, decklids and front-end carrier modules are increasingly designed using a multi-material mix to decrease weight while maintaining design flexibility, styling and safety performance. Structural bonding of these lightweight modules delivers on these customer needs.

“For those Tiers and OEMs adopting mixed-material design, 3 kg to 10 kg weight savings per module have already been realised,” states Christophe Van Herreweghe, Marketing Manager – Body & Exteriors, Dow Automotive Systems. “Use of Dow structural adhesives helps enable those targets and further enhances the module through the ability to bond dissimilar substrates, reduce welding and mechanical fasteners, seal against corrosion for better durability and increase strength and stiffness for crash worthiness and enhanced customer driving experience.”

Dow adhesives are developed with rapid-cure characteristics that process well in mass production manufacturing environments. Primerless-to-plastic formulations help remove VOCs from assembly operations, and new multifunctional adhesives are in development.

Structural bonding of modular assemblies has a success record of over 20 years. Dow products are on current platforms including the Jeep Cherokee liftgate – through collaboration with Magna – and will be launched on other 2019 series later this year.
