Abstract:
The invention relates to a preparation for the treatment of metallic surfaces, comprising at least water, at least one emulsifier and 0.1 to 10 wt. % of a wax or a mixture of two or more waxes.
Abstract:
The invention relates to a metal surface, which is coated with a polymer layer containing at least one polymer that is not soluble in water and at least one water-soluble polymer, whereby the layer thickness of the polymer layer is equal to 2 mu m or less. The invention also relates to a method for reducing the susceptibility of a metal surface to fingerprints, according to which a metal surface is coated with a less than 2 mu m thick layer of a polymer mixture containing at least one water-soluble polymer and at least one polymer that is not soluble in water or is coated with a compound of general formula (I) Y-R -X comprising at least two acid groups.
Abstract:
Physically and/or chemically setting binders are modified by fats, in particular esters of fatty acids or fatty alcohols, specially triglycerides of higher fatty acids, preferably natural fats and oils. They may be added in high concentrations to the binders, in particular synthetic polymers such as homo- and co-polyvinylacetate, without neutralising their binding properties. Their admixture improves wetting properties, water resistance and above all hardness. In particular dispersion glues, hot-melt-type glues and glue sticks may be improved with these binders.
