MATERIALS: ITW Devcon’s Tru-BondTM Dual Cure Adhesives cure to a hard, scratch-resistant surface with UV light, visible light, heat, or combinations of light and heat. They are ideal for producing protective, decorative, and dome coatings as well as for potting, wire tacking, and tamper proofing applications.
In the presence of air, the free radicals in most UV acrylic adhesives react with atmospheric oxygen and, through a process known as oxygen inhibition, interfere with surface curing. The result is often a slimy or tacky surface, and expensive high-intensity UV lamps are required to ensure proper curing. The unique chemistry of Devcon® Dual Cure Adhesives, however, overcomes oxygen inhibition barriers to allow curing with low-cost, low-intensity black lights. In fact, standard fluorescent black lights rated as low as 15 watts (available at most hardware stores) are sufficient to cure Tru-BondTM Dual Cure Adhesives totally tack-free. These adhesives can be used to produce thick, wrinkle-free surfaces because their depth of cure is greater than most UV-cured coatings. They can also be tinted with pigments to create almost any color as well as unusual visual effects.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
