The present disclosure describes aqueous adhesives comprising, inter alia, adhesives and saccharide fatty acid esters, particularly unsaturated fatty acid esters (uSFAE), including aqueous adhesive compositions containing such a combination and where such aqueous adhesive compositions show improved water resistance compared to adhesives which do not contain said uSFAE. Articles of manufacture comprising said aqueous adhesive compositions are also described.

The present disclosure relates to the technical field of building additives, and in particular to a preparation method of modified starch ether for improving the anti-sliding property of a ceramic tile adhesive. The preparation method includes chemical modification of subjecting starch to one-step etherification to obtain starch ether, followed by physical modification. In the preparation method, the cumbersome multi-step etherification in existing methods for preparing modified starch ether is avoided, and only one-step etherification is used to obtain modified starch ether of better properties. Because physical modification is added, the obtained product can significantly improve the anti-sliding property of a ceramic tile adhesive. Moreover, the conditions for one-step etherification are significantly different from the prior art.

The invention relates to a dimensionally stable preparation which can be abraded on flat materials, containing a translucent water-based polymer-containing carrier composition and platelet-shaped solid particles. The platelet-shaped solid particles have an average maximum diameter ranging from 2 to 40 μm and are contained in the preparation in a proportion by volume specified by the selected particle size in order to achieve a sheen which is clearly perceptible to the human eye while simultaneously having good abrasion properties. In a sub-aspect of the invention, the preparations according to the invention further have adhesive properties such that the abraded film is best suited for securing flat decorative elements or generally for adhering flat porous materials.
