Abstract

1,088,297. Etching. SPERRY RAND CORPORATION. June 16, 1965 [June 29, 1964], No. 25470/65. Heading B6J. An etchant for etching metal comprises ferric chloride, chromic-sulphuric acid, or copper chloride-hydrochloric acid, to which is added 3-8% by weight of a thixotropic agent such as colloidal silica, causing it to gel.
