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.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
