Types of Epoxy ResinsTypes of Epoxy Resins

Epoxy resins have higher levels of viscosity and are moulded at 50-100% temperature ranges. Catalysts or curing agents like accelerators or hardened can act either through a catalytic action or through a direct reaction with the resin.

Here are the common types of epoxy resins you can come across in various applications.

1. Heat-Cured Epoxies

These epoxies have numerous industrial applications, but these cannot be used in the construction sector, since they have a high requirement of heat to cure. Even the ones that would react at minimized heat levels require exposure to a temperature of 200-degree Fahrenheit. 

The resin has the best resilience and can find use in various industrial applications like electronic components, medical devices, missile warning machines, infrared telescopes, etc.

2. Two-Part Epoxies

The two-part epoxies help you to separately package the two various components required to create a chemical reaction. While the resin mixes up with hardener, it evolves from thick liquid to putty in about 24 hours and finally to a hardened cured material. To take off the epoxy once it is set, you should scrape it away after softening it using alcohol or paint thinner if required.

The two-part epoxies suit many industrial applications like aeronautical, automotive, manufacturing, and building. They also suit the construction projects that incorporate concrete elements fastening, countertops to substrates attaching, protecting decorative mouldings, etc.
