What are epoxy Binders and resins
Epoxy resins are a highly adaptable group of oligomers and polymers which undergo thermosetting — or curing — when a hardening agent (commonly referred to as an epoxy hardener) is added to the epoxy to develop desired properties. The chemistry of epoxies can be manipulated to produce a myriad of molecular weights, viscosities, and other characteristics. This flexibility makes them suitable for a wide range of end-user applications, from binding countertops and coating floors to molding aircraft components and manufacturing wind-powered turbine blades. Epoxies are a unique chemistry that can be used in a variety of adhesives, coatings, inks, and composite applications.
Epoxies are broadly used in modern industry. Epoxy formulators make use of the versatility of epoxies to meet specific commercial needs to individual industries like those in paints, coatings, adhesives and composites. It is highly recommended that formulators and applicators only work with epoxy resin and epoxy hardener suppliers that can meet the full demands of your business.
Fortunately, when working with Brenntag, you will gain access to a global network making Brenntag an industry leader in the distribution of epoxy resins and hardeners.
Popular Applications of Epoxy Binders and Resins
From all-purpose consumer epoxy adhesives to general industrial coatings preventing the corrosion of steel pipes in the oil and gas industry, various epoxy binders and resins are used extensively for their adhesion, coating, and insulation capabilities.
What follows are some of the most popular applications for epoxy resins and binders, as well as the industries that employ them:
Because of their strength, as well as their resilience to chemicals and heat, epoxies are used widely as a structural or engineering adhesive in the assembly and construction of high-performance equipment, including automobiles, boats, aircraft, snowboards, skis, and golf clubs. Moreover, epoxies’ versatility is prized, since they can be modified to adhere to almost any material, including metal, stone, wood, glass, and even select plastics.
In just about every hardware store, packs of epoxy can be found sold together in dual containers of a resin and binder. Their consumer uses range from general adhesion jobs to repairs on boats and even aircraft. However, since most epoxies break down with extended exposure to ultraviolet light, their outdoor uses normally require the application of a UV protective coating after they have cured.
With top-notch electrical insulation capabilities, epoxy resins help protect circuit boards, transistors, and integrated circuits from debris, moisture, and short circuiting. In addition, when circuit boards are made of glass cloth layers, epoxy resins are often used to sandwich and seal the layers together.
From marine to automotive applications, epoxies used in priming
paints and coatings help protect metal surfaces from corrosion. The
food packaging industry utilizes a variety of epoxy technologies to protect the food containers from rusting and breakdown caused by acidic foods (e.g. tomatoes), while preserving the integrity and
flavor of packaged good.
Epoxies are largely replacing traditional mold materials, such as metal and wood, in the casting, molding, and modeling of various components and composite parts in industrial tooling.
Chemical Properties of Epoxy Resins
In comparison to other thermoset plastics and polymers, epoxy resins have distinct chemical properties that make them an advantageous and practical choice for many industrial purposes. The chemical benefits of epoxies include the following characteristics:
- High resistance to moisture
- High resistance to other chemicals
- High resistance to impact
- Excellent electrical insulation properties (Note: Epoxies infused with silver, on the other
hand, demonstrate excellent conductivity.)
- Low shrinkage after curing
- Extended shelf life
