Chomerics introduces electrically conductive silver epoxy coatings for EMI shielding
Chomerics Europe has introduced two new electrically conductive coatings to provide EMI shielding of electronic equipment enclosures. CHO-SHIELD 576 and 579 provide shielding levels up to 80dB in the 30MHz to 1GHz range. Both may be applied by either conventional spray equipment or a brush.
CHO-SHIELD 576 is a highly conductive two-component silver-filled epoxy coating. It provides excellent EMI and environmental protection when applied to glass, plastic or epoxy substrates and it may be copper or tin plated after application.CHO-SHIELD 579 is also a two-component, silver-filled coating. The material has been specifically developed to have a low level of volatile organic compounds (VOCs) and achieves a VOC rating of just 357 grams/litre – 40% lower than its predecessor.
Both new CHO-SHIELD materials are touch-dry in less than one hour at room temperature. However, the best final electrical properties are achieved by curing the material at elevated temperatures.
CHO-SHIELD 579 is available in 454g tins, whilst CHO-SHIELD 576 may be supplied in either 454g or 2.270Kg tins.
