Continuous production process, solvent-free and mastication sensitive to pressure sensitive adhesives based on non-thermoplastic elastomers, and their application as a coating to produce self-adhesive articles.
1999
Manufacturing process continuously without solvent and without mastication, self-adhesive mass (14) based on non-thermoplastic elastomers in a machine working continuously and having a feed zone (2) and a zone of manufacturing compound (5), It is consisting of a) feeding the solid components of the self-adhesive composition (14), such as elastomers and resins, into the feed zone (2) of the machine, optionally introduction of fillers, colorants and / or crosslinkers, b ) transport of the solid components of the self-adhesive composition (14) of the feed zone (2) to lazona Manufacturing compound (5), c) adding the liquid components of the self-adhesive composition, such as plasticizers, crosslinkers and / or other tackifying resins, to the area of manufacturing compound (5), d) production of a homogeneous self-adhesive composition (14) in the area of manufacturing compound (5) e) discharge of the PSA.
