Abstract
Additives for application in construction chemistry are proposed comprising an organic and/or inorganic core component A) with rheology-enhancing properties and a shell component B) applied to the same by virtue of physical and/or chemical interactions which acts as a coating. Component A) should be a of water-soluble and/or water-swellable and/or water-absorbable compound of the non-cellulose type with viscosity-enhancing properties in the final application. The shell component B) should preferably be a film-forming polymer which is able to release component A) during the application in construction chemistry in a retarded manner such as for example polyvinyl alcohol, polyvinyl acetate and polyethylene glycol. Component B) can be composed of several layers and comprises at least one reactive layer. The new additive is used as an additive with a time-delayed action in paints and also for timed control of the increase in viscosity or development of rheology in building material systems based on inorganic binders.
