    摘要： The invention relates to rheology control kits for thickening two- or multi-component systems, comprising at least one module A containing (a1) at least one inorganic thickener and (a2) at least one wetting and dispersing agent that inhibits the thickening effect of the inorganic thickener (a1) and at least one module B containing (b1) at least one polymer that at least partially removes the inhibition of the thickening effect of the inorganic thickener (a1). The invention also relates to two- and multi-component systems into which modules can be incorporated, latent thickeners comprising module A and the use of latent thickeners in order to equip components with a latent thickening effect.

    摘要： The invention relates to a urea preparation containing (A) 5 to 75 wt. % of one or more urea components which have a molecular weight of at least 350 g/mol and contain at least one urea group; (B) 15 to 95 wt. %, preferably 30 to 80 wt. %, of one or more organic solvents from the group of N alkyl amides that have a molecular weight of 155 to 700 g/mol, are free of urea groups, and have the following formula (I), in which (a) R1 is an x-containing hydrocarbon group, where x=1 to 24 carbon atoms, R2 is a y-containing organic group, where y=1 to 12 carbon atoms, and R3 is a z-containing organic group, where z=1 to 12 carbon atoms, or (b) R1, R2, and R3 are defined as in (a) but R1 and R2 are connected to each other by a chemical bond and together form a ring with 4 to 10 ring atoms while incorporating the group C(═O)N, and in the case of a ring with 4 or 5 ring atoms, R3 contains at least 6 carbon atoms and maximally 11 carbon atoms, or (c) R1, R2, and R3 are defined as in (a) but R2 and R3 are connected to each other by a chemical bond and together form a ring with 4 to 10 ring atoms while incorporating the nitrogen atom of the general formula (I) with the proviso that for each of (a), (b), and (c), x+y+z≧8; (C) 0 to 35 wt. % of one or more organic solvents which differ from (B) and do not contain urea groups or ionic groups and which have maximally two heteroatoms selected from the group consisting of nitrogen and oxygen; and (D) 0 to 50 wt. % of a salt which differs from the urea component(s) (A), the solvent(s) (B), and the solvent(s) (C), wherein the sum of all of the stated weight percentages equals the total weight of the urea preparation. The invention further relates to the use of the urea preparation as a rheology additive for liquid compositions and to liquid media which contain the urea preparations.

    摘要： The invention relates to polyisocyanate adducts obtainable by reacting at least one polysiloxane of the structure (I), at least one polyisocyanate having at least three NCO groups, at least one (meth)acrylate of the structure (II), where U is one of the following groups: (III), and optionally a compound reactive with isocyanates. The indices m, n, x and y assume values of 0 to 100. In addition, t=2 to 30, s=1 to 400 and i=1 to 5. The radicals identified by the letter R are suitable organic groups. ASi is an OH—, NH2— or CO2H— group. In addition, m+n+x+y≧3. The invention further relates to a process for preparing the polyisocyanate adducts and to a radiation-curable coating composition comprising at least one radiation-curable polymer as a binder and at least one inventive polyisocyanate adduct. The invention further relates to the use of the inventive polyisocyanate adducts as an additive.
