Patent number: 9127195Abstract: A quantity of insoluble solid particles is coated with a hydratable gelling agent to produce a composition comprised of a mass of discrete solid particles which is dry and flowable. The composition is made by placing a binder on the insoluble solid particles and then, while the binder is sticky, placing a hydratable gelling agent on the sticky binder to thereby form the composition. The hydratable gelling agent on the composition, upon contact with an aqueous liquid, operates to increase the viscosity of the aqueous liquid.Type: GrantFiled: October 9, 2012Date of Patent: September 8, 2015Assignee: Fritz Industries, Inc.Inventors: James C. Ferrell, Jr., James J. Lavene, Trinidad Munoz, Jr.
