Epoxy Resin is a material chemically produced from a reaction between epichlorohydrin (ECH) and bisphenol-A (BPA). Several processes may be achieved depending on the type of epoxy resin desired. It was first used only a couple decades ago for the first time since polyester resin was the traditional substance used.
The most effective and durable surfboards are made with passion and finesse. Although most companies today program machines to achieve this task, there are many shapers that still manually make their surfboards, such as Greg Noll. The use of epoxy resin has revolutionized the sport such that professionals today require its advantages. Depending on the type of surfboard desired, different procedures are applied. An example of such can be seen in the following figure.
The first and most important property that makes this material special is its adhesiveness, which is due to the presence of hydroxyl groups and ether bonds. Hydroxyl groups easily form hydrogen bonds and ether bonds provide suitable reactivity, therefore once applied into surfboards it merges with any other material resulting in a stable as well as sturdy compound.
