Use of a copolymer (A) preparable by free-radical polymerization of a) at least one olefinically unsaturated monomer and b) at least one olefinically unsaturated monomer different than the olefinically unsaturated monomer (a) and of the general formula I R1R2C═CR3R4 (I), in which the radicals R1, R2, R3 and R4, in each case independently of one another, are hydrogen atoms or substituted or unsubstituted alkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl radicals, with the proviso that at least two of the variables R1, R2, R3 and R4 are substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals; in an aqueous medium for producing molding compounds and moldings.
摘要:
The invention relates to aqueous dispersions. They are obtainable by polymerizing an ethylenically unsaturated monomer or a mixture of ethylenically unsaturated monmers [sic] in an aqueous solution of an at least partially protonated epoxide-amine adduct. It is characterized in that the epoxide-amine adduct is for its part obtainable by reacting (A) a glycidyl ether of a polyphenol that contains on statistical average at least one epoxide group in the molecule, or a mixture of such glycidyl ethers, (B) a polygycidyl [sic] ether of a polyol that contains on statistical average more than 1.0 epoxide groups in the molecule, or a mixture of such polyglycidyl ethers, and (C) a compound that contains a primary amino group in the molecule, or a mixture of such compounds, to give the epoxide-amine adduct, components (A) and (B) being employed in a ratio of equivalents of from 1.0:0.5 to 1.0:8.0 and from 0.3 to 0.7 mol of component (C) being employed per equivalent of epoxide groups of (A) and (B).
摘要:
Aqueous dispersions entirely or substantially free from volatile organic compounds, comprising (A) at least one block copolymer preparable by two-stage or multistage free-radical copolymerization in an aqueous medium of a) at least one olefinically unsaturated monomer selected from the group consisting of hydrophilic and hydrophobic olefinically unsaturated monomers, and b) at least one olefinically unsaturated monomer different than the olefinically unsaturated monomer (a) and of the general formula I R1R2C═CR3R4 (I) in which the radicals R1, R2, R3 and R4 each independently of one another are hydrogen atoms or substituted or unsubstituted alkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl radicals, with the proviso that at least two of the variables R1, R2, R3 and R4 are substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals; and (B) hydrophilic nanoparticles; processes for preparing them, and their use as or to prepare coating materials, adhesives, and sealing compounds.
摘要:
A two-coat coating system for producing a two-coat coating, comprising (A) a composition of a transparent radiation-curable or radiation-curable and thermally curable clearcoat material, comprising at least one hydroxy-functional binder, and (B) a pigmented coating composition, the pigmented coating composition comprising at least one blocked, water-soluble or water-dispersible isocyanate.
摘要:
Method of preparing single-layer or multilayer color and/or effect films comprising a color and/or effect layer, by (1) continuously applying a component amount of a basecoat material (A) by means of a directed application technique to a carrier, the applicator (1) and the carrier being in relative motion with respect to one another, to construct a portion of the color and/or effect layer, (2) at least once, continuously applying the remainder of the basecoat material (A) and/or a basecoat material (B), which is different than the basecoat (A), to the component layer (1) formed by an application technique (2) which in the resulting component layer (2) induces no arrangement of the pigments in a preferential direction, the applicator (2) and the carrier being in relative motion with respect to one another, to further or fully construct the color and/or effect layer, and (3) drying or partly or fully curing the color and/or effect layer.
