Epoxy Coatings Guide pdf. Epoxy coatings are generally packaged in two parts that are mixed prior to application. The two parts consist of 1 an epoxy resin which is cross-linked with 2 a co-reactant or hardener. Epoxy coatings are formulated based upon the performance requirements for the end product. When properly catalyzed and applied epoxies produce a hard chemical and solvent resistant finish. They are typically used on concrete and steel to give resistance to water alkali and acids. It is the specific selection and combination of the epoxy component and the hardener component that determines the final characteristics and suitability of the epoxy coating for a given environment.
What are Epoxy Resins?
Resins Used In Composites. What is Epoxy Resin. Wind turbine blades often use epoxy resin. Sean Gallup/Getty Images News/Getty Images. Updated November 24 2014. The term epoxy has been widely adapted for many uses beyond fiber reinforced polymer composites. Today epoxy adhesives are sold in local hardware stores and epoxy resin is used as the binder in counter tops or coatings for floors.

Jump to navigation search. This article is about the thermoset plastic materials. For the chemical group see epoxide. A syringe of 5-minute epoxy glue containing separate compartments for the epoxy resin and the hardener. Structure of the highly reactive epoxide group present in all epoxy resins. Epoxy is a term used to denote both the basic components and the cured end products of epoxy resins as well as a colloquial name for the epoxide functional group. Epoxy resins also known as polyepoxides are a class of reactive prepolymers and polymers which contain epoxide groups. Epoxy resins may be reacted cross-linked either with themselves through catalytic homopolymerisation or with a wide range of co-reactants including polyfunctional amines acids and acid anhydrides phenols alcohols and thiols.

In the epoxy resin however these reactive sites are formed by epoxy groups instead of ester groups. The absence of ester groups means that the epoxy resin has particularly good water resistance. The epoxy molecule also contains two ring groups at its centre which are able to absorb both mechanical and thermal stresses better than linear groups and therefore give the epoxy resin very good stiffness toughness and heat resistant properties. The figure below shows the idealised chemical structure of a typical epoxy. Note the absence of the ester groups within the molecular chain. Epoxies differ from polyester resins in that they are cured by a hardener rather than a catalyst.
