Master Bond's Polymer System EP37-3FLF is an optically clear, two
component epoxy with resistance to cryogenic temperatures and severe thermal
cycling. Its low exotherm also makes it useful for potting, encapsulating and
casting systems, especially where wider cross section thicknesses are
specified. Its combination of properties allows it to cure without stressing
Serviceable over the range of 4K to 250F,
EP37-3FLF cures at room temperature in 2 to 3 days or faster at elevated
temperatures. This epoxy offers a non-critical 1 to 1 mix ratio by weight or
volume, and a low mixed viscosity of 1,400 to 1,500 cps. Users can work with a
100 g mass of the adhesive at room temperature for up to 90 mins.
EP37-3FLF has a bond shear strength exceeding
2,000 psi and a T-peel strength of 25 pli. This flexible epoxy has an elongation
of 180 percent and electrical insulation properties with a volume resistivity
of 1x1014 ohm-cm. It bonds to a variety of substrates including metals, glass,
ceramics, rubbers and many plastics and is widely used in the optical,
electrical, electronic, computer and OEM industries.
EP37-3FLF is sold in pint, quart, gallon and 5
gallon container kits and has a 6 month shelf life if unopened and stored at
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.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
