Two new electromagnetic shield coatings, specially formulated to meet EMI requirements, have been launched by Trimite as part of its 'Paints for Plastics' product group.

Designated J190 and J191, both coatings have been specially designed to give excellent coverage and adhesion to most commonly used plastic substrates such as ABS, PVC, Noryl and various commercial blends.

The very high conductivity achieved of 0.3 ohm/sq.in results in reduced costs and increased productivity.

J190 is a silver based coating.

The formulation provides electromagnetic compatiblity on plastic housings for a wide range of products.

It meets the EMI requirements and provides excellent electromagnetic discharge through a low film thickness.

Shield Coating J191 is a silver coated copper system.

It offers similar characteristics to J190 but requires a heavier film thickness to obtain full shielding properties.

Both products are suitable for direct application to thermo plastics but require a primer on thermoset plastics such as GRP, SMC, DMC and Glass Reinforced Phenolics.

The two new products complement Trimite's existing J2904 Plastilac Electromagnetic Shield Coating which is a nickel-filled product used on a wide range of plastic housings.

It conforms to all major EMC regulations and is suitable, without priming, for use on most plastic substrates.
