Non-etherified reaction product of a cyclic urea and a multifunctional aldehyde

The invention relates to a coating composition comprising a reaction product UA of at least one multifunctional aldehyde A with at least one cyclic urea U, and a crosslinkable resin having at least one kind of functional groups selected from the group consisting of hydroxyl functional groups, acid functional groups, amide functional groups, amino functional groups, imino functional groups, mercaptan functional groups, phosphine functional groups, and carbamate functional groups, characterised in that the degree of etherification, measured as the ratio «(13 O—R)/«(U) of the amount of substance n(—O—R) of alkoxy groups as substituents of the aldehyde carbon atoms of the multifunctional aldehyde chemically bound in the reaction product UA to the amount of substance «(U) of cyclic urea U chemically bound in the reaction products, is less than 0.01 mol/mol, and to a process for the preparation of the reaction product UA.

Fluid Activatable Adhesive for Glue-Free, Liner-Free, Labels for Glass and Plastic Substrates and Methods of Use Thereof

Methods for applying a liner-free, or liner-less label, to a substrate, particularly glass or plastic (e.g., polyethylene terephthalate) substrates, are described herein. The method includes applying an adhesive composition, such as a polymeric coating, to a label face sheet, activating the adhesive composition with an activating fluid, and contacting the label to the substrate. The activating fluid is preferably a mixture of water and one or more organic solvents, such as low molecular weight alcohols.

Wetting and anti-foaming agent

A wetting agent according to Formula (I): wherein R 1 is selected from a branched alkyl group or linear alkyl group or a cycloaliphatic group or an aromatic group, each having 6 to 15 carbon atoms; R 2 is selected from hydrogen, methyl, or ethyl; R 3 is selected from hydrogen, methyl, or ethyl; R 4 is selected from hydrogen, methyl, or ethyl; R 5 is selected from methyl or ethyl; x ranges from 0 to 5; y ranges from 0 to 10; z ranges from 1 to 10; with the proviso that when x ranges from 1 to 5, R 2 is different from R 3 ; and with the proviso that when x=0, R 3 is different from R 4 . The wetting agent also imparts anti-foam properties to aqueous solutions while reducing surface tension.
