Adhesives are able to bond diverse materials to similar or different substrates, thereby making the use of lighter materials in auto manufacturing possible. According to the American Chemistry Council, the use of one kilogram of adhesives can reduce vehicle weight by 25 kilograms or more. Adhesives manufacturer Henkel says that its work with Ford on its F-150 model enabled a weight reduction of 700 pounds (317 kg).
Apart from Lightweighting by reducing the amount of riveting needed and allowing the use of new materials, automotive adhesives are also used to improve vehicle safety, reduce Noise, Vibration and Hardness (NVH), protect electronic components and improve production line efficiency. By implementing adhesives technology, the automotive industry is following the lead of aerospace manufacturers such as Boeing and Airbus, but still lags behind the aerospace industry in taking advantage of the benefits of adhesives.
However, it seems that the regulatory environment and the need for innovation will encourage auto manufacturers to increase their use of adhesives, resulting in greener, safer cars and improved manufacturing efficiency.
