Introduction 

Elevated temperature resistant epoxies are a type of polymer that are designed to maintain their structural integrity and bonding properties at high temperatures. These epoxies are commonly used in applications where exposure to extreme heat or thermal cycling is expected, making them ideal for use in a wide range of industries such as heavy industrial mining, petrochem, wastewater, pulp & paper, coal & fire power plants, steel plants, those are a few of the industries and they are available in many forms, adhesives, putties, and coatings. 

Key Features 

One of the key features of elevated temperature resistant epoxies is their ability to maintain their strength and adhesive properties at temperatures that would cause standard epoxies and other adhesives to weaken or lose their effectiveness. This is achieved through the use of specialized epoxy resins and hardeners (which can be found in both a two-part epoxy mix and single part epoxy curing systems) that are capable of withstanding elevated temperatures without degrading. For example, consider a food safe epoxy and how important it withstands high temperatures even if the product it protects is exposed to high temperature. 

Common Uses 

Most common uses of elevated temperature resistant epoxies are in the petrochemical industry for oil and gas pipelines. They are used to protect metal that’s exposed to the harsh chemicals which are often pressurized at elevated temperatures in very corrosive environments which require great wear resistance & temperature resistance. These epoxies are also used in the mining industry for potash, iron ore, co-pet, and other high-temperature applications. In coal fire power and steel works, high temp epoxy applications involve repairing and protecting scrubbers and repairing worn pipes and coal mills. 

In addition to their high temperature resistance, elevated temperature resistant epoxies also offer excellent chemical and moisture resistance, making the cured epoxy mix, or system, ideal for use in other harsh environments such as industrial manufacturing and processes. Whether using dispensed beads for small applications, to large areas, or deep pour epoxy, poured epoxy or self-leveling epoxy, they can be applied to a wide range of substrates, including metals, ceramics, plastics, and composites, and can be formulated or compounded to provide other specific properties such as electrical conductivity or thermal insulation. 

Elevated or higher temperature resistant epoxies can do what their conventional counterparts, or lower temperature performing epoxies can do, and perhaps more with their added temperature resistance. With their range of capabilities, high temperature resistant epoxies go beyond being insulative. Epoxy resins and even primer epoxy can afford other applications such as lining tanks, repairing equipment (as with epoxy metal and epoxy for aluminum), and be successfully used in intumescent applications. 

Know Your Epoxy Adhesive & Epoxy Coating Needs 

However, there are some drawbacks to using elevated temperature resistant epoxies and their popular epoxy clear coats. These adhesives and coatings are typically more expensive than standard epoxies and may require more special handling and curing procedures. In addition, their high temperature resistance can make them more difficult to remove or rework if necessary, so knowing the correct product for your specific application is important.
