Epoxy adhesive

Epoxy glue or epoxy adhesive is glue that contains epoxy resin as the main ingredient. The epoxy is the resin produced by the condensation reaction in which a polyhydric compound and epichlorohydrin are reacted in the presence of alkali. Epoxy adhesive is a two component material, the epoxy resin and the hardener that will crosslink the epoxy to make a dry, hard and strong bond. The hardener is chemical that will react with the epoxy groups, including amines, thiols, hydroxides, and acid groups, but amines are the most common hardeners.
The epoxy glue is a versatile adhesive is widely used for various purposes such as: the building construction, bicycles, sports equipment, boats, decking and even the aircraft construction. Epoxy adhesive can be used to glue the glass, metal, plastic, wood, and iron. It can be made in wide range performance from the clear, transparent, to the opaque performance; it can also be formulated in an elastic or rigid, fast or slow dry. In the wood adhesive, the epoxy is widely used for outdoor furniture, boats, decking or construction. The adhesive has some advantages such as: cure at ambient temperatures, have good gap filling ability, and available to bond with many other substrates. The epoxy glue can be used to produce a bond to the wood as well as for in-place repair of the damaged wood at structural members.
But the fact that the uses of epoxy adhesive in wood adhesives is quite less. It could be caused by two factors, the price is relatively expensive and the unsatisfied bonding result. The study and test carried out to the epoxy adhesive showed high failure compared with other types of glue that is cheaper and easier to be used. Two major factors that contribute to durable wood bonds are less creep and its ability to withstand the tension caused by changes in humidity of the wood.
