Floors/flooring epoxy resin dispersions

Two-component epoxy resin water thinned dispersions are now being used as floor sealers. They have good adhesion to concrete as well as good chemical resistance. However, the particle size of the dispersion is comparatively large (approximately 1-1.5 microns) and consequently penetration into good-quality concrete is minimal and an on-surface seal is obtained. However, with porous low-quality concrete substances, considerable binding/strengthening, etc. of the surface can be achieved with water-dispersible epoxy resin-based floor sealer. 

For the purpose of the swelling behavior, sensitive parquet formats with bright decoration, such as beech and maple, require the development of both water- and solvent-fi-ee reactive resin flooring adhesives. In addition to epoxy, resin adhesives used in Germany are mainly polyurethane adhesives. The environment-friendly way to glue flooring is undoubtedly the use of water-based dispersion parquet adhesives. These consist of polyvinyl acetate polymer dispersions and binders such as chalk and mineral fillers.
