What is Epoxy?
Epoxy is an organic compound made up of chains of carbon linked to other elements such as hydrogen, oxygen, or nitrogen. This link occurs via a covalent bond, in which the elements share a pair of electrons to stay together.

Creating Epoxy Adhesives
Epoxy resin and hardener curing conditions can be modified to create the desired mechanical strength and property in the material. This means choosing the right temperature or humidity settings for the curing process to obtain epoxy materials that are resistant to heat, electricity, or chemicals. As a result, a variety of epoxy adhesives have been developed to suit a broad range of applications from automobiles to golf clubs. They are suitable for any product requiring a high strength adhesive and can be used on a variety of materials.

Two-Component Epoxy Adhesives
Two-component epoxy adhesives are also known as a two-part epoxy. They are cured at lower temperatures compared to one-component systems. The curing is done with the help of catalysts, and the process can be accelerated by heat. Cross-linking in the polymers increases during this heat acceleration process to give the epoxy superior properties.

Two-component epoxy adhesives are highly stable. They also have a wide variety of applications, such as bonding, sealing, and coating. They can be treated to resist high temperatures and have fast curing times.

Choosing the Right Epoxy Adhesive
One factor to consider when choosing an epoxy adhesive is the work life. This is how much time an epoxy adhesive takes to harden and dry. However, this is not to be confused with cure time, which refers to the length of time it takes for the internal chemical reactions to complete and the epoxy to reach its full strength.

A good example would be the long work life polyamide epoxy adhesive versus a metal bonding epoxy adhesive. Both are made by Bigbong Glue, and both require 24 hours to become completely cured. However, the long work life polyamide epoxy has a work life of 200 to 700 minutes, while the metal bonding epoxy has a work life of only 9 to 12 minutes.

To choose the right epoxy adhesive based on work life, simply determine the approximate length of time your job will take. You do not want your epoxy adhesive to harden and dry before your job is finished, nor do you want your materials to shift and slide after your job is complete because your epoxy adhesive has not dried and hardened in time.
