Epoxy Adhesives

Epoxy adhesives are characterised by their excellent electrical properties and chemical resistance, strength and low absorption of moisture. They make great adhesives and are also one of the few types of glue that can be used on metals and glass. Epoxy is a two part adhesive that is formed when you mix epoxy resin and a hardener. These versatile adhesives offer high strength resistance to corrosion. The high strength to weight ratio and dimensional stability as well as adhesion properties make them ideal for a wide range of applications. Different resins are produced by varying the ratios of the chemical components.

What is epoxy adhesive used for?

Epoxy adhesives have a variety of uses and are essential when a reliable and strong bond is required, meaning they are often used in manufacturing or construction work. Other applications include general purpose adhesives for at home projects, and as a gap filler for reconstructions. The glue once hardened can be sanded, drilled and painted which results in a wider variety of applications.

How are they made?

Most epoxy resins are an industrial product derived from petroleum and are themselves the result of a chemical reaction called curing. This involves epoxies and other chemicals more commonly known as hardeners or curing agents. Depending on the type of reaction used to produce them, they can be either low-molecular honey-like liquids or high-molecular, solid substances. Their molecular weight often determines their potential uses and applications.

Advantages of Epoxy

  • Low shrink during cure
  • Excellent moisture and chemical resistance
  • Good electrical properties
  • Increased mechanical and fatigue strength
  • Impact resistant
  • No VOCs (Volatile Organic Compounds)
  • Long shelf life
