Epoxies require clean surfaces compatible with the adhesive. 

Advantages:

• high strength
• low shrinkage during cure
• toughness
• resistance to chemical and environmental damage

Most epoxies are two-part adhesives cured at room temperature Thermally cured or thermoset one-part epoxies systems are also available. Depending on the formulation, epoxy resins are used as potting agents, resin binders in fibreglass construction, electrical conductors and various structural bonding applications.

Epoxy adhesives are available in a wide range of chemical compositions, which allow for a number of different setting styles. 

Setting styles include:

• single component setting
• dual-component setting
• thermosetting curing
• radiation curing (which includes UV, EB and visible light curing)

Single component epoxy adhesives

Single component epoxy adhesives consist of one resin that hardens by reaction with surface moisture, a surface applied activator-primer, or through the application of heat.

Dual or multi-component adhesives

Dual or multi-component adhesive or sealant systems consist of two or more resins or a resin and a hardener, crosslinker, activator or catalyst that when combined react and cure into a polymerised compound or bond. Two component epoxy adhesive systems are mixed and then applied.

Thermoset epoxy adhesives

Thermoset epoxy adhesives are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins do not melt and flow when heated, but they may soften.  Phenolic, melamine and urea formaldehyde resins are thermosetting adhesives that offer strong bonds and good resistance to high temperatures.  Vulcanisation is a thermosetting reaction involving the use of heat and/or pressure in conjunction with a vulcanising agent, resulting in greatly increased strength, stability and elasticity in rubber-like materials. RTV silicone rubbers are room temperature vulcanising materials.  The vulcanising agent is a crosslinking compound or catalyst.  Sulphur is the traditional vulcanising agent used with natural rubber.

Silicones

Silicones use moisture, acetic acid and other compounds as curing agents.

UV or radiation cured epoxy adhesives

UV or radiation cured epoxy adhesives use ultraviolet light, visible light or electron bean irradiation to initiate curing, which allows a permanent bond without heating or excessive heat generation. One disadvantage of UV curing adhesives is the requirement that one substrate is UV transparent.  Some UV resin systems employ a secondary curing mechanism to complete curing of adhesive regions shielded from the UV light.

EB curable epoxy adhesives

EB curable epoxy adhesives use electron beam radiation to cure or initiate curing.  The electron beam can penetrate through material that is opaque to UV light.
