Master Bond UV22DC80-1 is a nanosilica filled, dual cure epoxy based system. Nanosilica filled epoxy formulations are designed to further improve performance and processing properties.

The specific filler will play a crucial role in determining key parameters such as viscosity, flow, aging characteristics, strength, shrinkage, hardness, and exotherm. As a dual curing system, UV22DC80-1 cures readily upon exposure to UV light, and will cross link in shadowed out areas when heat is added.

Dual cure systems are effective for rapidly fixturing parts with the UV portion of the cure, and then concluding the process by adding heat. Watch this video to see a dual cured epoxy in action.

This compound features exceptionally low shrinkage upon cure, outstanding dimensional stability, and resists abrasion. It is not oxygen inhibited. It withstands chemicals such as acids, bases, fuels and solvents. It is electrically insulative with a volume resistivity greater than 1014 ohm-cm. It is optically clear, with a refractive index of 1.52.

The low viscosity ranges from 500 cps to 3500 cps. The temperature serviceability extends from -100°F to 300°F. UV22DC80-1 bonds well to metals, ceramics, glass, rubber, and many plastics. It passes NASA low outgassing certification and is used in high tech applications including aerospace, optical and opto-electronics.

Economics Drives Ray-Gun Resurgence

Laser weapons, cheaper by the shot, should work well against drones and cruise missiles

In an artist’s rendering, a truck is shown with five sets of wheels—two sets for the cab, the rest for the trailer—and a box on the top of the trailer, from which a red ray is projected on an angle, upward, ending in the silhouette of an airplane, which is being destroyed

Lockheed Martin's laser packs up to 300 kilowatts—enough to fry a drone or a plane.

The technical challenge of missile defense has been compared with that of hitting a bullet with a bullet. Then there is the still tougher economic challenge of using an expensive interceptor to kill a cheaper target—like hitting a lead bullet with a golden one.

Maybe trouble and money could be saved by shooting down such targets with a laser. Once the system was designed, built, and paid for, the cost per shot would be low. Such considerations led planners at the Pentagon to seek a solution from Lockheed Martin, which has just delivered a 300-kilowatt laser to the U.S. Army. The new weapon combines the output of a large bundle of fiber lasers of varying frequencies to form a single beam of white light. This laser has been undergoing tests in the lab, and it should see its first field trials sometime in 2023. General Atomics, a military contractor in San Diego, is also developing a laser of this power for the Army based on what’s known as the distributed-gain design, which has a single aperture.
