Development of Resorcinol Formaldehyde (RF)-Free Adhesive for Rubber Reinforcing Materials


NSG Group is pleased to announce that we have developed an adhesive for rubber reinforcement materials that does not contain resorcinol and formaldehyde* (RF), chemical substances of concern for environmental and human health hazards, for our Glass Cord products.


The adhesive developed by the NSG Group this time applies our proprietary adhesion technology already successfully developed for belts in oil and uses a newly developed coupling agent as a substitute for RF, which is harmful to the human body, thereby eliminating the risk of leakage of hazardous chemicals and contributing to a reduction in environmental impact. In addition, it achieves adhesive performance equivalent to that of conventional RFL adhesives. Furthermore, it is characterized by the fact that it can be widely used as an adhesive for not only glass fiber but also polyester, carbon fiber, aramid fiber, and other fiber cords.
