This fire-retardant epoxy fills gaps and bonds well to concrete, wood, glass, fabrics and metals. It is mixed as it is dispensed, with a viscosity of 80,000 cps. It has a working time of 10 minutes, fixes in 20 minutes and cures functionally at 72F in three hours. It has low VOC emissions, is solvent free and its bonds will pass the federal 60-second vertical burn test (14 CFR 25.853/25.885). In cured form, it has a peel strength of 25 pli, resists 10 ft-lbs/in2 impacts, has a dielectric strength of 800 V/mil, and has an adhesive tensile lap shear strength of up to 2,900 psi (as tested on grit-blasted steel at 144F).
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
