摘要:
Process for the continuous solvent-free and mastication-free production of self-adhesive compositions based on non-thermoplastic elastomers in a continuously operating apparatus having a filling section and a compounding section, comprising a) feeding the solid components of the self-adhesive composition, such as elastomers and resins, into the filling section of the apparatus, optionally feeding of fillers, colorants and/or crosslinkers, 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, such as plasticizers, crosslinkers and/or further tackifier resins to the compounding section, d) preparing a homogeneous self-adhesive composition in the compounding section, and e) discharging the self-adhesive composition.

摘要:
Pressure-sensitive hotmelt adhesive composition based on non-thermoplastic elastomers, obtained bya) preparing, as the preliminary batch, a composition comprising the elastomers and one or more of the following additives such as fillers, anti-ageing agents, plasticizers and tackifier resins in an intensively shearing, intensively cooling mixer and without solvent, the composition having a final temperature of from 100.degree. C. to 160.degree. C.,b) mixing and homogenizing the preliminary batch in a second mixer with one or more of the following additives such as fillers, anti-ageing agents, plasticizers and tackifier resins, without solvent, the composition having a final temperature of from 100.degree. C. to 160.degree. C.,where the total residence time of the composition at temperatures over 100.degree. C. does not exceed a figure of 6 minutes, so that the resulting hotmelt adhesive composition has a viscosity of more than 900 Pa*s, in particular from 900 Pa*s to 1200 Pa*s, at 130.degree. C. and at a shear gradient of 100 s.sup.-1.
摘要:
Adhesive tape comprising a backing comprising an oriented thermoplastic film and a coating comprising a solventlessly prepared pressure-sensitive adhesive composition based on non-thermoplastic elastomers such as natural rubber and tackifying resins, characterized in that the pressure-sensitive adhesive composition comprises a thermally labile crosslinking system.
摘要:
Process for producing adhesive tapes in which adhesive tapes coated on one side with an adhesive composition are subjected to radiation crosslinking, the irradiation of the adhesive tape taking place through the backing material of the adhesive tape onto the adhesive composition in such a way that the backing material and that side of the adhesive composition facing the backing material receive a dose of from 30 to 200 kGy, in particular 100 kGy, and the acceleration voltage during the irradiation being chosen such that the dose on the open side of the adhesive composition has fallen from 0 to 60 kGy, in particular from 10 to 20 kGy.
