Abstract
The present invention relates to the use of nanoparticles for the preparation of water-based dispersion adhesives, and especially the use of finely divided barium sulfate therein. The nanoparticles can be used with or without chemical modification. Adhesives of this kind feature improved properties, examples being improved cohesion in conjunction with comparable adhesion and higher heat resistance. Preference is given to dispersion adhesives based on polyacrylate, polyurethane, and epoxy resin.
Claims27
A method of use of nanoparticles for the preparation of water-based dispersion adhesives, wherein the nanoparticles have a primary particle size smaller than or equal to 500 nm and, optionally wherein at least some of the primary particles are present in the form of secondary particles, the secondary particles having a size smaller than or equal to 1000 nm.
