US Patent:

45540497, Nov 19, 1985
Filed:

Jun 7, 1984
Appl. No.:

6/618159
Inventors:

Edwin W. Bastenbeck - Plymouth CT
Assignee:

Enthone, Incorporated - West Haven CT
International Classification:

C09K 1304
C09K 1306
C23F 100
C23G 108
US Classification:

156656
Abstract:

Stripping solutions comprising hydrogen peroxide and sulfamic acid in correlated amounts are effective for the rapid and selective removal of nickel from mild steel surfaces and nickel, nickel alloy and nickel reaction products from alloy substrates. The compositions contain sulfamate, nitrate and chloride and peroxide ions and, preferably, an iron complexing agent such as ethylene diamine tetraacetic acid.

US Patent:

47755571, Oct 4, 1988
Filed:

Nov 9, 1987
Appl. No.:

7/118811
Inventors:

Edwin W. Bastenbeck - Plymouth CT
Juan Haydu - Orange CT
Richard A. Bellemare - Watertown CT
Assignee:

Enthone, Incorporated - West Haven CT
International Classification:

B05D 310
US Classification:

427307
Abstract:

A process for specially conditioning and etching a polycarbonate resin prior to metal plating to enhance the coverage and adhesiveness of metal plating to the resin. The swellant composition comprises a compound represented by the general formula, R. sub. 1 (OC. sub. n H. sub. 2n). sub. m O--R. sub. 2 wherein R. sub. 1 and R. sub. 2 are independently selected from the group consisting of aryl groups and alkyl groups of 1-4 carbon atoms, n is 2 to 4 and m is 1 to 5. The swelled resin is then etched using, preferably, a highly alkaline composition such as a solution containing greater than about 100 g/l NaOH. Other etchants such as chromic acid may also be used. The resin is now ready for plating using conventional techniques.

US Patent:

46632409, May 5, 1987
Filed:

Nov 6, 1984
Appl. No.:

6/668753
Inventors:

Juan B. Hajdu - Orange CT
Edwin W. Bastenbeck - Plymouth CT
Assignee:

Enthone, Incorporated - West Haven CT
International Classification:

B32B 1504
US Classification:

428545
Abstract:

An RFI shielded enclosure and a process for making same are disclosed. The process comprises coating at least one surface of the enclosure with a fluid organic binder having a substantial percentage of catalytic particles suspended therein. The particles used cause the electroless deposition of copper or nickel to produce an RFI shielded enclosure having in excess of 40 dB's shielding at frequencies above 10 kiloHertz.
