Abstract:
Process for the continuous solvent-free and mastication-free production of self-adhesive compositions based on non-thermoplastic elastomers from solid components and liquid components in a continuously operating apparatus having a filling section and a compounding section, comprisinga) feeding the solid components of the self-adhesive composition into the filling section of the apparatus, optionally also feeding fillers, colorants, crosslinkers, or a combination thereof, b) transferring the solid components of the self-adhesive composition from the filling section to the compounding section, c) adding the liquid components of the self-adhesive composition to the compounding section, d) preparing a homogeneous self-adhesive composition in the compounding section, and e) discharging the self-adhesive composition, f) coating the self-adhesive composition on a web-form material, where the coating of the web-form material is carried out using a multi-roll applicator unit, so that the self-adhesive composition is shaped to the desired thickness as it passes through one or more roll nips, and where the rolls of the applicator unit are optionally individually set to temperatures from 20Â° C. to 150Â° C.
