Epoxies have improved how we build just about everything.  They have improved the way industries world wide adhere, reinforce, insulate, coat, beautify, and strengthen. Let’s take a look at what epoxies are, how they work, their varieties, and how Powerblanket can be your epoxy curing partner.

What is Epoxy?

Epoxy is a reactive compound that consists of an epoxy resin and a curing agent or hardener. It begins with a basic epoxide structure which consists of 2 hydrocarbons bonded to a single oxygen atom. These atoms contain highly reactive bonding sites that allow them to bond with a wide range of substances.

Epoxides will react with almost anything, which means they react very well with hardening agents to cure into a strong finished material. Epoxy can be combined with a wide range of composite materials and other substrates for industrial applications that require:

• Durability (low degradation)
• Low shrinkage
• Flexible strength
• Excellent adhesion to substrates
• Electrical insulation
• Chemical and solvent resistance
• Moisture resistance

A Brief History

The first documented scientific investigations into epoxy reactions began in several countries (United States, Switzerland, Germany) shortly before World War II. These experiments were not very successful and it took several years for the first actual patent to be filed. A US scientist, Caston Greenlee secured the first patent for a commercial epoxy resin in 1943 but did not start manufacturing until 1947, when the war was over.

Other manufacturers began to realize that epoxy bonded extremely well to a variety of surfaces and could be used for coatings, adhesives, reinforcements, and more. Over the years, people have experimented with different fillers and additives to make epoxy an even more versatile tool.

What are Epoxy Composites?

Because of its ability to bond and cross link with a wide range of materials, epoxy can be combined with different additives and fillers to increase its performance and versatility. Epoxies will often get renamed according to its additives. Some of these additives include:

• Reinforcing fibers (graphite, glass, polyaramid) to increase structural integrity
• Powdered metals (to improve thermal and electrical conductivity)
• Silica (to increase strength)
• Mica (to increase electrical resistance)
• Carbon and graphite powders (to increase lubricity)
• Liquid rubber (to increase flexibility and crack resistance)
• Thermoplastics (to increase crack resistance)
• Flame retardants (decreases flammability)
