COKOON: An open source, resorcinol-formaldehyde-free bonding system for textile reinforcements

Continental and Kordsa, a global reinforcing materials supplier primarily to the tire industry, have jointly developed a resorcinol formaldehyde-free dip technology for bonding textile reinforcements to rubber-based compounds. Given the key applications in the tire industry, the transition to this new adhesive technology presents a significant challenge. To address this, both companies have adopted a free licensing model for the bonding system, promoting an open-source approach. Continental continuously analyzes and reviews the raw materials used in the production of its tires. With COKOON, the company has succeeded in replacing resorcinol and formaldehyde in the production of tire fabrics.
