New Adhesive Foot Coverings Could Replace Summer Sandals

Posted By ASC, Thursday, July 13, 2017

Whether it’s for serious business or just for fun, adhesives have become an important part of our everyday lives. But things may be about to get even more fun, with a new adhesive foot covering that could replace summer sandals for active folks. It’s just like being barefoot, but without the hazards of nasty cuts to the undersides of the feet or the discomfort we feel when walking on sun-baked sand or poolside paving. When you want to swim, simply take to the water with your foot coverings still firmly in place.

The footprint-shaped sticky patches cover the soles of the feet. Users peel off the adhesive backing and apply the brightly-coloured sticky patches to the soles of their feet. Now, they can clamber over rocks, stroll on hot beaches, and enjoy a swim without worrying about cutting their feet on sharp objects and without ruining summer sandals in the wet. When they’re done, they simply peel off the foot covering. The bright new concept, known as NakeFit, received funding through Kickstarter, where it exceeded its targets thanks to widespread public interest.

PermalinkComments (0) Article Details How Adhesives Overcome Disadvantages of Mechanical and Thermal Fastening

Posted By ASC, Wednesday, July 12, 2017

Before modern adhesive technologists came up with advanced adhesives, engineers chose one of two methods: mechanical or thermal fastening. Today’s market demands, advanced materials and complex manufacturing requirements demand much more from manufacturers however.

The adhesive industry has responded with innovative and highly effective methods to meet these increasing demands and complexities, while addressing some of the inadequacies of traditional fastening methods.

Let’s look at some of the disadvantages of mechanical fasteners:

  • They add weight
  • They usually require holes that weaken components
  • They leave very visible bond lines
  • They carry all load at specific points, contributing to fatigue
  • They do not separate dissimilar materials and that can cause corrosion
  • Thermal fastening offers an alternative, but also has its disadvantages:
  • The substrates must be thick enough
  • They’re hard to disassemble, rework or repair
  • The aesthetics aren’t perfect
  • They require skilled labor and can pose a hazard to workers


Combining adhesives and tapes with mechanical and thermal fastening methods or utilizing adhesives alone gives engineers a smorgasbord of options for attaching materials to one another while overcoming difficulties and adding key benefits:

  • Adhesives and tapes allow for faster assembly
  • They can be stronger than welds
  • They are more flexible
  • They bond and seal at the same time
  • More...

BLOG:  “As Received” and Adhesive Performance
By Jim Swope, Expert Blogger (The ChemQuest Group, Inc.)

In my early days as a supplier of adhesives to automotive assembly operations, I dreaded the words “as received” on a specification because its implied meaning could affect adhesive performance (light mill oil commonly used as a rust preventative by parts suppliers is often the culprit).

Mill oils may not present major problems in assemblies where the adhesive process is augmented by mechanical methods such as spot welds or the adhesive process displaces the oil. However, when the adhesive is carrying the full load (no mechanical augmentation) or the operating conditions are extreme, surface contamination will present issues. A clean surface is commonly understood as being critical to repeated success in bonding. Sometimes the parts supplier would insist their parts are cleaned prior to shipping but further probing would reveal they added a rust preventative in the final rinse or as a subsequent process. The presence of a rust preventative can retard or arrest chemical cures or act as a barrier to proper wetting of the surface.The outcome of which is classic weak link theory: The assembly fails due to weakening of a critical component – the adhesive interface to the substrate.

What steps can be taken to assure that we avoid failure in critical assemblies? How do we balance that against cost pressures? Who bears the cost burden of proper surface preparation?

The answer lies with the specification writer who ought to own not only the bonding specification but the condition of the substrates that are critical to the assembly... Read More

Henkel and Fiat Chrysler Partner in Lightweighting, Improved Process, and Performance Drive

Posted By ASC, Thursday, July 6, 2017

Henkel and Fiat Chrysler have been working together during the last three years, arriving at new treatment processes that will be used for the first time in the new Alfa Romeo Giulia. The adhesives resulting from this collaboration will advance the trend towards lightweighting using new materials and mixed materials such as a combination of aluminium and steel.


Apart from reducing weight, the materials will allow for body and pain shop improvements in noise reduction and stronger structures. The new Giulia’s body is 90kg lighter than it would have been without Henkel’s input, and both weight and performance have benefitted from the partnership. 

Much of the lightweighting comes through the use of aluminium, and to improve corrosion performance, the Bonderite pre-treatment process developed with Henkel has proved to be the solution. Acoustic performance improvements are realized through the use of Henkel’s Teroson expansion pillar fillers. These consist of a foamable elastomer that is inserted into the body. When exposed to the heat of the e-coat oven, they expand, filling the internal gaps that would otherwise transmit noise.


In addition, Fiat Chrysler will be replacing bitumen pads used for noise dampening with a spray-on acrylic waterborne sound deadener. Not only is it lighter, it also deadens the noise of vibration better. The product will also save Fiat Chrysler money since it can be applied in a fully automated process.


Further opportunities for automation are presented by the Teroson PV3414 sealant for internal and external seams. Once again, the product not only allows for labour savings, but presents an improvement on the products previously used in terms of the finished product according to the company.

PPG's Chrome-Free Aerospace Sealant Meets Military Specifications

Posted By ASC, Wednesday, July 5, 2017

At this year’s Paris Air Show, PPG announced that its new chrome-free sealants had been given full approval for use in military aircraft. Apart from presenting a more environmentally sustainable option than older forms of such sealants, additional advantages accrue. The Nato NSN approval awarded to the sealants means that the new materials can be adopted without any need for further purchasing approval.

PPG has two chrome-free sealant products with differing uses. The first of these, PR-1425CF, is a polysulfide windshield and canopy sealant. It can be used on polycarbonate, glass or acrylic windows and will cure in in half the time needed for older iterations of the product.PPG’s PR-2870 sealant, on the other hand, is used for aerodynamic smoothing. It can also be used to seal structural surfaces, be used for fay sealing, or to seal pressure fuselage. Both sealants will cure within 12 hours.

Diagnostic Adhesive Patch for Sleep Apnea Shows Promise

Posted By ASC, Monday, July 3, 2017

Doctors currently use cumbersome equipment to diagnose sleep apnea. Unfortunately, many patients struggled to sleep at all during polysomnography tests. Now, clinical trials on an adhesive patch that weighs less than an ounce have shown that it can produce accurate diagnoses. The information it gave to researchers was 87.4 percent as accurate as that produced by standard polysomnography.


The new SomnaPatch measures blood oxygen, nasal pressure, pulse rate, body position, sleep time and respiratory effort. Patients will be able to apply the patch at home, collecting up to four hours of sleep data.The study authors say that the device is a low-cost solution that will allow for sleep apnea diagnosis without disrupting sleep. It is yet to be approved by the FDA, but researchers say that their study will provide the information the organization needs to evaluate the new device during the approval process. Somnarus Inc, the company behind the innovation, has presented its results to sleep medicine specialists, and the abstract of its study was published in the journal Sleep.
