Demand for wind turbines is set to treble over the next ten years. At the same time there is a trend to even larger turbines, challenging the adhesives used in assembling blades even more. Consequently, getting adhesive choice and dispensing right is more important now than ever before.

Installations of wind turbines to generate power have been cropping up all around the world in the past decade. As oil supplies threaten to dwindle, and concerns about global warming mount, we can expect to see even more. Estimates predict that wind power output will triple over the next ten years1, and could possibly fulfil all the world's energy needs by the middle of the century. Today the production of the wind turbines that would allow this is reliant on adhesives.The design of wind turbines owes a lot to modern aircraft manufacturing. Beyond the aerofoil design of their blades, some of the pioneers in producing composite materials for aircraft have been quick to offer their products to the wind power industry. They typically offer epoxy adhesives, which they can also use in producing the lightweight structural materials they sell.
