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.
Claims21
A hardenable composition comprising a hardenable monomeric, oligomeric, or polymeric component, a hardening agent therefore, wherein the hardenable component or hardening agent is contained in a reaction-hindering protective casing which can be ruptured by the usual pressure normally used in applying such compositions, and microhollow spheres which are of sufficient strength to withstand rupture by said normal pressure, the amount of said spheres being at least 1% by weight based on the weight of the hardenable component.
