Hardener are usually added to epoxy resins as a second component. And due to the strength of adhesion, flexibility and waterproofing properties that they have, they have many applications in various industries. Common species of epoxy hardeners are anhydride, amine, polyamide, aliphatic and cycloalifate.
What is Hardener?
It can be a reactor or catalyst in a chemical reaction that occurs during the mixing process. For example, in some mixtures, a hardener is simply used to increase the strength of the mixture. But in another mixture, it can be used as a restorative.
Hardeners are almost always necessary to prepare epoxy resin for their intended purpose. Epoxies can never be achieved without the remarkable mechanical and chemical properties that hardeners can achieve without them.
Hardeners are used to correct epoxy resins. However, adding a hardener to the epoxy resin may prevent the epoxy mixture from being corrected quickly enough. In this case, another hardener may be needed. Hardeners with special additives can also be used. These hardening additives act as catalysts that speed up the cooking process.
Hardeners have very good mechanical strength, high adhesion to the surface, very good resistance to acids, and can also easily remove all kinds of contaminants and grease from the surface of epoxy resins.
Despite all the features listed above, research should always be done on resin and hardener to ensure that the final epoxy mixture performs well.
These materials are widely used in industry, for example, as a raw material in paint factories, to make a variety of epoxy tables and jewelry, as well as for flooring in hospitals and pharmacies, ships and heavy primers, and building adhesives.
