MATERIALS:Master Bond EP30M3LV is a specially engineered, low exothermic epoxy system formulated to help avoid excess heat buildup and damage to thermally sensitive components during potting operations. It also contains a special additive to remove air bubbles. This compound cures at room temperatures or more rapidly at elevated temperatures, and can be cured in various cross section thicknesses. EP30M3LV has a volume resistivity of 2×1015 ohm cm at 25C. It has a convenient 2:1 mix ratio by weight and an advantageously low mixed viscosity of 2,000-3,000 cps. It has a service operating temperature range of -60 to 250F. EP30M3LV also has superior dimensional stability, a flexural strength of 14,000 psi and a tensile strength of >8,000 psi. Master Bond EP30M3LV is environmentally friendly, 100 percent reactive and contains no solvents or diluents. It is available for use in half-pint, pint, quart, gallon and 5 gal pail kits.
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.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
