Abstract (en)
[origin: EP0877121A1] A suspension (I) for the solvent free production of silicone resin bound paper consists of: (A) 100 pts.wt. of a layer silicate, (B) 100-10,000 pts.wt. water, (C) 0.1-5 pts.wt. of a silane of formula (R<1>O)aSiR4-a (1), (D) 1-50 pts.wt. of a particulate silicone resin of formula (R<1>O)bSiRcO(4-bc)/2 (2), (E) 0.01-20 pts.wt. of a catalyst for the hydrolysis and/or condensation of compounds of formulae (1) and/or (2), and (F) optionally other known additives, whereby for each pt.wt. of (C), 5 pts. wt. (D) are present. In the formulae, R = 1-20C hydrocarbon; R<1> = 1-10C alkyl, aryl, alkylaryl or H; a = 1-3; b = 0-0.5; and c = 0.7 - 1.3 Also claimed is the production of the suspension (I) by mixing (A), (B) and (C) for at least one minute followed by the addition of (D).
