This In addition to these two main types of paint, there are other types of paint that you need to become familiar with. These include elastomeric, direct to metal DTM and epoxy. Elastomeric is an exterior paint that has rubber-like qualities. This is a good choice for some wood surfaces due to the fact that it bridges over small cracks and can stretch with the surface. DTM paint is generally an industrial finish although sometimes you may find it available to the public. This is primarily an exterior product and can be applied to steel siding with great results. Epoxy paint is chemical resistant and very tough. This two-component paint is mostly used on interior surfaces and is as tough as it gets. It is ideal for jobs that need a tough finish, such as garage floors. -659 In the years of 18311832, Michael Faraday discovered the operating principle of electromagnetic generators. The principle, later called Faradays law, is that an electromotive force is generated in an electrical conductor that encircles a varying magnetic flux. He also built the first electromagnetic generator, called the Faraday disk, a type of homopolar generator, using a copper disc rotating between the poles of a horseshoe magnet. It produced a small DC voltage.
