Structural adhesives with high bond strength are needed to meet the high requirements in the aerospace, transportation and automotive industry. The trend towards lightweight materials leads to an increased demand for structural adhesives, which are able to bond dissimilar materials such as steel, aluminum, thermoplastics and composite materials.
To increase the range of electric vehicles, manufacturers are reducing their weight. One measure: the EV-batteries are assembled using structural adhesives instead of mechanical fastening. The batteries must be reliably fixed so that they remain firmly in place even in the event of accidents and strong vibrations. Silane-based structural adhesives guarantee such a secure bond. Even the most demanding substrates (e.g. aluminum grades, PET foil) and different materials can be reliably bonded with them. The silanes also make sure that the adhesives have the right rheology for automatic application by robots. With DYNASYLAN®, Evonik offers a broad portfolio of crucial and technically relevant silane additives: For demanding, long-lasting structural adhesives that withstand the impacts of accidents, that prevent corrosion and that can be customized according to substrate requirements.
Label-friendly, Low-Odor, High-Performance: VISIOMER® Specialty Methacrylates for Structural Bonding
Methacrylate-based adhesives offer strong bonding to a wide range of metals and polymers with minimal surface preparation. They are valued for their rapid curing time, proven durability, and ability to provide high shear, peel, and impact strength while resisting chemicals and corrosion. Unlike conventional reactive methacrylates like MMA and THFMA—often linked to either high volatility, flammability, strong odor or strict hazard classifications—Evonik’s VISIOMER® Specialty Methacrylates, including VISIOMER® BNMA and Terra IPGMA, provide innovative, label-friendly and low-odor to nearly odorless alternatives. These monomers enhance user safety and comfort, support regulatory compliance by reducing VOCs, and are listed under TSCA and REACH. Partially bio-based, VISIOMER® Terra methacrylates like VISIOMER® Terra IBOMA lower environmental impact while delivering uncompromising performance, such as high mechanical strength and temperature resistance —making them ideal for next generation adhesive solutions across industries.
