Patents by Inventor Olivia R CROMWELL

Olivia R CROMWELL has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • SURFACE APPLIED CORROSION INHIBITOR
    Publication number: 20210214564
    Abstract: A sealer composition for a cementitious substrate, a cementitious structure sealed with the sealer composition, and a method of sealing a steel reinforced cementitious structure with the sealer composition. The sealer composition includes a substantially non- aqueous blend of a first silane, a second silane having a higher molecular weight than the first silane, and a corrosion inhibitor. The corrosion inhibitor is soluble in silane, soluble in solvent-diluted silane, and at least partially soluble in water. The cementitious structure includes a cementitious substrate and the sealer applied to the surface of the substrate and at least partially penetrating into the substrate. The method of sealing a steel reinforced cementitious structure from intrusion of corrosion-causing agents includes applying the sealer to the surface of a steel reinforced cementitious substrate and permitting the sealer composition to penetrate into the substrate to seal the substrate.
