VINNAPAS® EP 441 is a multi-purpose binder combining excellent nozzle application and high setting speed to offer faster production and reduced usage cost. The aqueous dispersion, based on vinyl acetate and ethylene, offers exceptional adhesive characteristics for paper and packaging applications. It was especially developed to support the continuing global trend of non-contact extrusion (“nozzle”) technology instead of roller application for paper converting.

In the nozzle application process, the binder is applied by pulsed dots through nozzles. This leads to reduced binder consumption and faster production speed, which results in higher productivity. To reach high flexibility in application, binders must combine good machinability for nozzle and roll applications, and show good performance with regard to other relevant properties such as setting speed.
