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. |
