sabrinacampagna: Peter Zimmermann. Kith and Kin, 2010Airbrush and epoxy resin. Epoxy, also known as polyepoxide, is a thermosetting polymer formed from reaction of an epoxide “resin” with polyamine “hardener”. Epoxy has a wide range of applications, including fiber-reinforced plastic materials and general purpose adhesives. Two part epoxy coatings were developed for heavy duty service on metal substrates and use less energy than heat-cured powder coatings. These systems use a 4:1 by volume mixing ratio, and dry quickly providing a tough, protective coating with excellent hardness. Their low volatility and water clean up makes them useful for factory cast iron, cast steel, cast aluminium applications and reduces exposure and flammability issues associated with solvent-borne coatings. They are usually used in industrial and automotive applications since they are more heat resistant than latex-based and alkyd-based paints. Epoxy paints tend to deteriorate, known as chalk out, due to UV exposure. Epoxy resin, mixed with pigment, may be used as a painting medium, by pouring layers on top of each other to form a complete picture.
