J-B Weld epoxy is a two-part adhesive that can bond various surfaces and withstand high temperatures up to 500 °F (260 °C) constantly and 600 °F (316 °C) for short periods. It is water-resistant, petroleum/chemical-resistant, acid-resistant, and resists shock, vibration, and temperature fluctuations.
SU-8 is a commonly used epoxy-based negative photoresist. Negative refers to a photoresist whereby the parts exposed to UV become cross-linked, while the remainder of the film remains soluble and can be washed away during development. As shown in the structural diagram, SU-8 derives its name from the presence of 8 epoxy groups.
In the 1960s, James A. Herbig and Ival O. Salyer of Monsanto were the first to attempt to make what would become ASA using butyl acrylate as the rubber phase. This work was then refined by Hans-Werner Otto and Hans Peter Siebel of BASF using a copolymer of butyl acrylate with butadiene for the rubber phase.
A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. [1] These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light.
Epoxy resin formulations are important in the electronics industry, and are employed in motors, generators, transformers, switchgear, bushings, insulators, printed wiring boards (PWB), and semiconductor encapsulants. Epoxy resins are excellent electrical insulators and protect electrical components from short circuiting, dust and moisture.
They sometimes lack the brushability and self-leveling qualities of solvent-based varnishes. Generally they have good UV-resistance. In the art world, varnishes offer dust-resistance and a harder surface than bare paint – they sometimes have the benefit of ultraviolet light resistors, which help protect artwork from fading in exposure to light.
