Latest Patents
Rauch-Puntigam's latest patents include innovative formulations for acrylate copolymer additives. One of his patents describes acrylate copolymers containing amino, hydroxyl, and fluorine groups, which are useful as additives for aqueous cationic coating systems. These additives help prevent surface flaws and improve the adhesion of subsequent coats, particularly in PVC-containing materials. The copolymers are designed to include a specific quantity of hydroxyl groups derived from monoesters of (meth)acrylic acid with diols, along with fluorine sourced from esters of (meth)acrylic acid. The recommended usage of these additives ranges from 0.5 to 5.0% by weight, based on the solids content of the binder in the coating system.
Another patent focuses on acrylate copolymers containing hydroxyl and fluorine groups as additives for aqueous anionic paint systems. These copolymers are formulated to prevent surface defects and include hydroxyl groups from hydroxyethyl (meth)acrylates or hydroxypropyl (meth)acrylates, as well as fluorine groups from 2-perfluoroalkethyl (meth)acrylate. The additives are utilized in amounts from 0.1 to 2.0% by weight, calculated on the total solids content of the binder in the paint.
