MATERIALS: NuSil Technology LLC announced the release of R-2182. This curable coating is designed to alleviate surface tackiness and blocking (sticking to themselves by virtue of chemical affinity) in applications in which silicones come in contact with each other or other surfaces, such as precision molded parts, molded rubber stoppers, O-rings, gaskets, accordions or cables/cable coatings. R-2182 can also be used to control the flow of hydrophilic fluids.
Silicone elastomers inherently have a high degree of surface tack which can present problems when storing, especially in cases where the silicone is likely to fold and unfold or spool together. R-2182 decreases the coefficient of friction of a cured silicone surface by at least 50 percent as compared to a non-coated silicone surface, so it is very well suited for these situations. In addition, it reduces the surface energy for masking by approximately 50 percent and has a high contact angle of 123 degrees.
R-2182 is a two-part, low-coefficient of friction silicone coating dispersed in xylene. A thin coat of R-2182 cures rapidly with elevated temperatures and, once cured, it chemically bonds to the silicone elastomer substrate, mimicking its mechanical properties. The result is a smooth and durable, yet flexible, coating that resists abrasion, stiction and friction from moving, sliding and rubbing parts.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
