Epoxy Adhesives
Epoxy adhesives are tough structural epoxies with both environmental and chemical
resistance. They are used to join components in a variety of industries, and
are widely used because of their bonding strength and durability.
Epoxies may consist of one component which hardens by contact with surface
moisture, or dual components that use other curing methods. This curing may
be accomplished using heat, UV light, visible light, radiation, and chemical
reaction. Dual component epoxies consist of a resin, and a hardener or activator
that is combined to react and cure into a polymerized bond. Dual component
epoxies are mixed, and then applied to the surfaces being bonded.
Epoxy adhesives are available in many chemical compositions, and often have
additives the increase strength, change viscosity, waterproof the adhesive,
reduce shrinkage, conduct or insulate the adhesive, resist chemicals, and adapt
to high or low temperatures.
These adhesives are used in many applications, from model-making to heavy
industrial applications such as automobile manufacturing.
