| Number | Title | Issue Date |
| 6875471 | Metallization of polymer parts for painting The quality of painted surfaces of polymeric articles is improved by depositing a coating of a metal such as zinc or zinc alloy on the surface of the article to be painted. For example, zinc is electrodeposited on a conductive surface of the article. The metal coate... | 04/05/2005 |
| 6872294 | Metallization of polymer composite parts for painting The quality of painted surfaces of polymer composites is improved by first forming an electroless metal coating on the molded surface of the composite and then electroplating a coating of zinc or zinc alloy on the metallized composite surface. The “galvanized” c... | 03/29/2005 |

| 5702584 | Enhanced plating adhesion through the use of metallized fillers in plastic substrate A polymer substrate is plated with a metal, using metallic filler particles in the polymer as anchorage points for a layer of metal formed by an electroless plating operation. The polymer has a filler that includes non-metallic filler particles and metall... | 12/30/1997 |
| 4775449 | Treatment of a polyimide surface to improve the adhesion of metal deposited thereon A method of improving the adhesion of metal applied on a polyimide surface is disclosed, in which the surface is first treated with an adhesion-promoting compound containing a nitrogen-oxygen moiety prior to plating of the metal thereon.... | 10/04/1988 |
| 4552626 | Metal plating of polyamide thermoplastics A process for metal plating filled thermoplastic resins such as nylon-6. The filled resin surface to be plated is cleaned and rendered hydrophillic and preferably deglazed by a suitable solvent or acid. At least a portion of the filler in the surface is r... | 11/12/1985 |
