I've instaled my QCS using aquaseal but AFAIK any urethane based adhesive would work
You may also send it to Celso Pontes who has made a superb work changing my old DUI CNSE zipper, and replacing a broken wrist QCS i myself installed some 10 years ago

Thanks for the indication. I found a product which description is similar to the Rema SC 2000, it's called Vipafix. I will give it a try.
