Abstract (en)
[origin: WO2022048728A1] The invention relates to cross-linkable substances containing: (A) 100 parts by weight of compounds of formula Y - [ (CR12) b- SiRa (OR2) 3-a ] x (I); (B) 5 to 2000 parts by weight of silicone resins containing units of formula R3 C (R4O)dSiO (4-c-d) /2 (II), in which the functional groups and indices have the meanings specified in claim 1, with the proviso that the sum of c+d is less than or equal to 3, in at least 40% of the units of formula (II) c is equal to 0 or 1, and the silicone resin has a polydispersity Mw/Mn of less than 5.0; optionally (C) organosilicon compounds comprising basic nitrogen; optionally (D) fillers; optionally (E) non-reactive plasticisers; optionally (F) catalysts; optionally (G) adhesion promoters; optionally (H) water scavengers; optionally (I) additives; and optionally [J] supplementary substances. The invention also relates to a method for the production thereof and the use thereof as adhesive, sealing and coating substances, in particular for bonding substrates.
