Abstract
Hardenable one-component substances composed of hardenable components and an activator wherein one of the components is contained in a reaction hindering protective casing to inhibit hardening until use are disclosed wherein, as an additional component, hollow microspheres are included. The microspheres provide increased stability to storage of the composition as well as enhance the rupture of the protective casing during activation and application of the substance and also provide a low specific gravity to the component. Methods for preparing and using the substances are also disclosed.
