Overview These adhesives are thermosetting polymer created from the reaction of epoxide 'resin' with the polyamine 'hardener.' These resins are used in a range of applications, including general use adhesives and fiber-reinforced plastic materials. Furthermore, they are a class of synthetic resins commonly utilized to make adhesives and plastics. They are highly acclaimed for their splendid adhesion, toughness, durability and high- resistance to heat and chemicals. Applications Functions of these resins are fundamental across numerous industries - it is used in glues, ad infinitum, putties and paints. Paints and Coatings Two-part epoxy coatings were formed for heavy-duty employment on metal surfaces and utilized less energy as compared to heat-cured powder coatings. They dry swiftly providing a durable protective coating with outstanding solidity. Their low volatility and easy water clean-up makes them bulls-eye for factory cast aluminum, cast iron and cast steel. They are widely used in automobile and industrial applications because they are more heat-resistant as compared to alkali-based and latex-based paints. Foams Epoxy resins are utilized to form lightweight, sturdy, foamy structures boasting of excellent insulation properties. Moreover, they are specifically utilized for foam-in-place applications in the casting and 'potting' process. These resins are produced either by blending a prefoamed filler in the liquid system or by a chemical reaction. Construction These resins are now utilized as binders in materials employed for construction. Typically, a 2-parts system consisting of diluents, thickening agents, fillers, curing agents and resins is used. They are utilized to bond concrete and to generate industrial smooth slender-set terrazzo floors. This application has been extended to the construction of buildings, roads and filling up the cracks in concrete structures. Adhesives The versatile characteristics of these resins make them extremely valuable as adhesives in military and civilian applications. Approximately 5% of total epoxy production is consumed as adhesive in a range of structural applications. These adhesives create strong bonds with all kinds of surfaces, with the exception of some non-polar surfaces. Laminates Laminated epoxy based insulations are widely utilized as rods, tubes and sheets. Paper, polyaramid fabric or sheets of woven glass with the B-stage epoxies are laminated in multiple pattern presses. In addition, they are utilized in preparing assemblies of polyaramid fibers or copper-clad glass for printed circuit boards in the electronics sector. These resins can be bought from hardware store, marine supply outlets, hobby shops, craft stores or online. However, when using epoxy resin, it is essential to follow certain safety measures. A person must work in a well-ventilated area and prevent inhaling the fumes of the product. He should also wear gloves and shades to protect his skin and eyes.
