Abstract: The present invention provides a comestible product having extended release of additives wherein the additives are mixed with a carrier containing from about 10 wt. % to about 100 wt. % of a microcrystalline material, the microcrystalline material having a particle size ranging from about 0.1 .mu.m to about 100 .mu.m. Additives which may be mixed with the microcrystalline carrier are flavors, sweeteners, vitamins, pharmaceuticals, minerals, colors, acids, and mixtures thereof. Examples of carriers are microcrystalline cellulose, zeolites, carbon black, and mixtures thereof. Examples of comestible products in which the additive/carrier blend may be used are chewing gum, bubble gum, instant beverages, and frozen desserts.

Abstract: Protective coating systems are reinforced by first laying a suitable mesh screen of plastic, metal or the equivalent on the surface to be protected. Thereafter, a thin layer of a coating composition, e.g., a latex cement, is poured over the mesh and allowed to set. In this operation the mesh is bonded by means of the coating composition to said surface. The screen also protrudes to the upper surface of said layer and when the latter has been allowed to set, a second layer is applied resulting in a system in which the reinforcing mesh not only aids in forming a durable bond between said first layer and said surface, but also likewise renders the two layers thus formed resistant to spalling or separating caused from expansion or contraction of said surface.
