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.

Like us on Facebook Follow us on Twitter. Home / Epoxy / Chemistry basics. Epoxies are created through reacting a hardener and an epoxy resin or by reacting the resins with themselves. Epoxy resins are a vast class of prepolymers and polymers containing more than one epoxy group also often referred to as glycidyl or oxirane groups. The majority of epoxy resins are an industrial product derived from petroleum and are themselves the result of a reactive process involving epoxide units cyclic ethers with three ring atoms. Depending on the type of reaction used to produce them cured epoxy resins can have variable chain lengths and purity grades corresponding to various molecular weights.
WEST SYSTEM Epoxy Resins and Hardeners.
Epoxy Resins and Hardeners. WEST SYSTEM epoxy cures to a high-strength plastic solid at room temperatures by mixing specific proportions of liquid epoxy resin and hardener. This highly moisture-resistant plastic adheres to a wide range of materials making it ideal for projects that require water and chemical resistence and strong physical properties for structural bonding. Select from a range of hardeners and additives that allow you to tailor the mixture's handling characteristics and the physical properties of the cured epoxy to suit your working conditions and specific coating or bonding application.

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. 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.
