Master Bond's EP21TDCHT-LO two part epoxy adhesive/sealant is specially formulated
for demanding applications where factors like temperature cycling, high
vibration and mechanical shock are an issue. It withstands cryogenic
temperatures and meets NASA low outgassing specifications. This versatile
system is used for a wide variety of structural, electronic, aerospace, medical
and oil and chemical processing applications. EP21TDCHT-LO has a convenient mix
ratio of 1:1 by weight or volume and is formulated to cure at room temperature
or more rapidly at elevated temperatures.
As a toughened
system, EP21TDCHT-LO is useful for bonding dissimilar substrates, especially
when they have differing coefficients of expansion. It has a service temperature
range from 4K to +350F. Other notable features include a shear strength
exceeding 2500 psi, a peel strength of greater than 20 pli and a Shore D
hardness of greater than 60. The cured epoxy is chemical resistant and is an
Parts A and B are
available in half pint, pint, quart, one gallon and five gallon containers.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
UK researchers have come up with a method for machining aerospace-grade, carbon fiber-reinforced composites, along with high-strength aerospace alloys, using an ultrasonically assisted machining device. It also works on high-strength aerospace alloys.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
