Electrically conductive silver plated copper coating 3800C
EMI/RFI shielding application for prototype and touch up work of plastic enclosures/housings
Conductive silver plated copper coating Is supplied ready for use, it is designed to give low resistance in thin film thickness, and exhibits superb EMI shielding and grounding properties displaying excellent adhesion to most plastics and is specially suitable for electronic equipment housing. It exhibits superb long term shielding and grounding properties while providing an esthetically pleasant appearance.
The resin becomes touch dry in approx. 5 minutes after application, to handle in 10 minutes and achieves maximum conductivity within 4 to 16 hours when air dried. It is intended to prevent electrical interference which penetrates enclosures made from thermoplastics and other insulating materials. The coating also prevents static build up.
It is recommended that an grounding connection is made to achieve maximum shielding performance. A suitable material for this is Part number 3201, Copper shielding tape which can simply be stuck onto the coated surface or over-sprayed with the electrically-conductive copper coating. The coating, once it has been applied, has a copper colored finish.
