Reactive PU Hotmelts solidify quickly after application, providing strong initial strength for bonds – perfect for working with no delays. They then react chemically with the moisture in the air or the materials around them to reach their ultimate high level of stability and adhesion.
The respective chemical formulations mean that reactive PU Hotmelts can adapt precisely to the requirements of the production process and the bonding point. This is thanks to their viscosity, the application window, the setting time and the time to complete chemical hardening.
OTTO did not invent reactive PU Hotmelts. But we are reinventing them to suit your requirements, perfectly adapted to your production process and what you need from the bonding point. We are also happy to work with leading manufacturers of application equipment. And, of course, in the precise quantity and form that you need.
