subject: Epoxy Resins Are The Most Useful Chemical Compounds Of Present Time. Really? [print this page] Epoxy is one those modern day chemicals that finds application in various industries. They were originally developed for use in the aerospace industry, however because of the versatile properties that this compound offers, has made it a favorite for a number of manufacturing industries.
If we have a look at the chemical nature of the compound, then epoxy can be termed as a copolymer that is made from the combination of two different chemicals - the resin and the hardener. Hardener is generally a monomer of polyamine like TETA (triethylenetetraamine) whereas the resinous chemical is a short chain polymer that contains epoxide group at both ends.
If we talk about the properties of epoxy resins, then there are plenty to discuss. Let us have a look at the places & industries where this chemical finds its application:
As an adhesive: Epoxies are considered one of the best adhesives available in the market at present times. They can be used on a variety of surfaces including wood, fiberglass, plastics as well as metals. The surface needs to be treated accordingly before using the resin. For instance, treatments like drying and sanding are generally carried out before applying epoxies.
Coatings & Paints: As a chemical used for coating, epoxies are much superior then solvent borne coatings, which are inflammable. Not only that, epoxy has a higher heat resistance as compared to latex based paints that makes it the perfect material to be used in automobile paints. The lower volatility & water cleanup properties of the compound have led to its application in factory cast iron and aluminum.
As a Composite in industrial tooling: Although epoxies are a little costly as compared to other resins used in the manufacturing of industrial tools, but their strength and high temperature resistance overcomes the cost factor. The resin is used to create molds, laminates and fixtures to be used for various industrial purposes.
Others: Apart from the above-mentioned industries, this multipurpose chemical is also finds application in marine and aerospace industry. It is also used in biological applications like embedding the samples in the plastic that can be then imaged under electron microscope. Artists use epoxy as a painting medium by missing the chemical with any colored pigment.
Looking at all the facts mentioned above, you could easily figure out as to why Epoxy resins have gained so much popularity as a useful chemical. Or is there any doubt still left?
