Epoxy is a thermosetting adhesive glue made of resin, which is used as a hardener. Epoxy is also used to adhere different surfaces together, which can withstand extreme stress and weather conditions. However, adhesive means sticking, whether it is on the surface of the object. Read More…
Epoxy AdhesiveEpoxy adhesives are tough structural epoxies with both environmental and chemical resistance. They are used to join components in a variety of industries, and are widely used because of their bonding strength and durability. These adhesives are used in many applications, from model-making to heavy industrial applications such as automobile manufacturing.

Epoxy adhesive is widely used in various industries as a type of glue to stick different structures together. Epoxy adhesives are made from many resins, and each type has different glue properties. For example, heat-resistant epoxy is the best choice if temperature resistance is required.
How to Make Epoxy Adhesives
Epoxy adhesives are made by polymerizing two components, the resin and the hardener. Additional additives such as filler, toughener, plasticizer, silane coupling agent, deformer, and colorant can be added when needed. Epoxy resins are made from the active hydrogen reaction from phenols, alcohols, amines, and acids with epichlorohydrin.
Curing is an exothermic reaction that begins when the resin is combined with a specific catalyst. By controlling the temperature, resin, and hardener choice, we can change the properties such as mechanical strength, and thermal, electrical, and chemical resistance in the curing process.
Classes of Epoxy Adhesives
Epoxy adhesives consist of one or two component glue systems, and each one of these is strong but has different curing processes, qualities, and applications. However, two- component epoxy resin adhesive is more durable than a single-component system.
Two-Component Epoxy Adhesive
Before the application of two-component epoxy adhesive, it is mixed so that both the components react with each other, causing the epoxy adhesive to cure. This adhesive is highly reactive and makes the strongest bonds. However, if the process needs to be accelerated, then heat or UV radiation should be applied. This adhesive is used to adhere to surfaces such as wood, metal, plastics, ceramics, and rubber.
Single-Component Epoxy Adhesive
This epoxy adhesive is easy and simple to use as it does not require mixing. In addition, this epoxy adhesive has a paste-like consistency and is ideal for filling gaps or seals that are usually present between metal surfaces.
Types of Epoxy Adhesives
The various types of epoxy adhesives are as follows:
DGEBA Epoxy Resin
DGEBA epoxy, also known as diglycidyl ether of bisphenol A, is the earliest known epoxy.
It is compatible with a wide range of catalysts that helps in creating a diverse spectrum of properties.
It is available in various forms, such as low molecular weight liquids, solids, semi-solids, and brominated resins.
Brominated resins are used in flame retardance applications.
Waterborne Epoxy Adhesives
Epoxies are hydrophobic; therefore, they cannot dissolve in water.
The mechanical and chemical stability of the adhesive is mostly determined by the surfactant used and the manufacturing parameters.
Epoxy Acrylate Resins
Two types of epoxy acrylate resins are used to make adhesives, vinyl ester and a specific resin for radiation curing..
These are simple to make and cure quickly at room temperature..
These epoxy resins have lower viscosity, more flexibility, and better wetting properties.
Flexible Epoxy Resin Glues
The use of flexible resins reduces the glue’s hardness.
It is mixed with modifiers to create tougher, stronger, and more flexible solutions.
Flexible epoxy resins are used for laminating safety glass and absorbing vibrations and sounds.
Flexible epoxy resins are also used for the encapsulation of electrical components.
Epoxy Novolac Adhesives
Epoxy novolac adhesives are well-known for being chemically and thermally resistant.
These epoxies should be cured at high temperatures for better adherence.
These resins are difficult to manufacture because they have high viscosity.
UV Hybrid Epoxy Adhesives
UV and thermal cure hybrid epoxy adhesives combine UV acrylate and thermal cure epoxy compositions.
The production efficiency can be improved by reducing the fixture time by UV radiation to seconds.
Applications of Epoxy Adhesives
Epoxy adhesives are used in applications that require harsh chemicals because they are highly resistant to chemicals.
It is also used in the automotive industry to dampen automobile vibrations and sounds.
Due to their exceptional strength and mechanical stability, epoxy adhesives are also used in the aerospace industry for binding helicopter blades.
Epoxy adhesives are also resistant to saltwater, which is why these are used in marine situations.
These adhesives are also used in the construction industry for outdoor use as they are weather resistant.
