Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. That's not surprising: automotive has some of the toughest performance requirements of any industrial application, and fitting any new material into the assembly of production cars is especially difficult. So solving adhesive performance and process challenges for automotive applications means it's a little easier for suppliers to come up with adhesives tough enough and production-friendly enough for a lot of other industrial and commercial uses.
The rest of these new products are for a wide variety of applications, including aviation, aerospace, electrical motors, electronics, industrial, fiber-optic, optical, microelectronic, semiconductor, and laser. They range from acrylic foam tape and one-coat bonding agents or two-coat primer and cover-cement systems, to two-part silicone adhesives or epoxies, fast-cure epoxies for use in dispensing guns, customized adhesive tapes and films, and UV- or visible light-curable methacrylate metal adhesives. Many of them are designed for bonding dissimilar substrate materials.

Germany-based chemicals maker Wacker Chemie and automotive technology transfer firm inpro Innovationsgesellschaft collaborated to develop ELASTOSIL RT 779, a two-part silicone adhesive for mounting plastic vehicle oil pans without mechanical fasteners or primers. The new product adheres to both aluminum and polyamide, possesses good sealing properties, and is highly resistant to oil, heat, and dynamic loads. It can be applied by machine and cures rapidly at room temperature, with a pot life of five to 10 minutes. Twenty minutes after mounting, the bond is strong enough to allow further operations on the engine and oil pan, slashing production cycle times. When fully cured, the adhesive has a bond strength much greater than 0.25 megapascals, which means the oil pan can now be mounted and sealed in one operation. inpro, a joint venture of Daimler, Volkswagen, SABIC, Siemens, and Thyssen-Krupp, develops advanced production systems in the automotive industry.

A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
