      Continental and Kordsa bring first series tires with Cokoon dip technology onto the road

      Hanover / Istanbul, February 20, 2020. Continental, the technology company and manufacturer of premium tires, and Kordsa, the global reinforcer, predominantly serving the tire industry, announced today that the series production of the first of 250.000 passenger car tires featuring their new sustainable adhesive technology began in 2019. The two partners have been working together on this new eco-friendly dip technology since 2017.

      This new technology enables the bonding activation of textile reinforcing materials with rubber compounds without the use of resorcinol and formaldehyde in the textile dip. Textile reinforcing materials are widely used in tire manufacturing, as well as in the production of mechanical rubber goods such as hoses and conveyor belts.

      Since the first announcement of Cokoon as an open innovation technology in March 2019, it has attracted a lot of attention within the industry. More than 40 companies (tire manufacturers, converters, and textile suppliers) have expressed an interest in testing the material and are considering joining the licensing pool. Some 20 of these have already received samples. Now, all of the interested parties have been invited to join the pool and obtain free licensing in order to contribute to the development of this new green technology. The licensing pool is handled by the independent law firm AdvInno. Companies can find more information and the appropriate contacts on the official website www.cokoon.com.

      “The sampling process was a big success and exceeded our expectations. Feedback from the industry encouraged us to proceed with the integration of Cokoon into our tires and to begin series production of the first tires back in 2019. Expanding use of the Cokoon technology in our tire production in 2020 and in the following years is a high priority for us,” says Dr. Andreas Topp, Vice President Material and Process Development and Industrialization at Continental Tires.

      Devrim Özaydin, Global Technology Director at Kordsa, outlines the underlying idea: “With Cokoon, we want to implement an eco-friendly industry-wide standard for bonding textiles and rubber. We therefore invite all interested parties to join the pool, obtain free licensing, contribute to the enhancement of this new open technology and introduce Cokoon into their mass production.”

      Eco-friendly resorcinol- and formaldehyde-free adhesion technology

      Cokoon is the brand name of a new bonding system technology which is offered to all other tire manufacturers and their suppliers as an open source solution. The development partners Continental and Kordsa have chosen to waive development or licensing fees. In return, they expect licensees to make their patents concerning the further enhancement of this technology available to the other partners free of charge via a licensing pool. Interested companies can request samples.

      Prior to Cokoon, the chemicals resorcinol and formaldehyde were irreplaceable in the bonding activation of textile reinforcing materials to the surrounding rubber matrix. The replacement of resorcinol and formaldehyde with more environmentally friendly alternatives is beneficial not only for a sustainable supply chain but also for tire cord manufacturers. It is worth noting that employees in tire plants and end-consumers are not exposed to these substances as they are chemically altered through the vulcanization process. With Cokoon dip technology, the bonding of textiles to rubber is now possible without these two substances and the technology does not require any changes in process equipment.
