Nagase Chemtex Develops Film Adhesive for Post-Vulcanization Diene Rubber

on February 1, 2024 in Innovation

Chemical products manufacturer Nagase Chemtex has developed a film adhesive for post-vulcanization rubber, which enables adhesion between metals and diene rubber such as natural rubber, butadiene rubber (BR), and low nitrile rubber (NBR) after vulcanization. The adhesive does not require primer treatment, which is necessary for liquid-type vulcanized adhesives, and the process can be shortened. Furthermore, it does not contain...
