A mask, preferably for high temperature applications, such as flame spray processes, welding or soldering. The mask consists of an uppermost sacrificial layer formed of a high temperature resistant polymer, a perforated metal layer, preferably a metal screen bonded to the lower surface of the sacrificial layer, a barrier layer formed of a high temperature resistant polymer and bonded to the lower surface of the perforated metal layer, an adhesive layer applied to the lower surface of the barrier layer and a release layer covering the adhesive until used. Additional layers and additives such as flame retardants may be used. A preferred additional layer is comprised of a vermiculite dispersion which is coated onto the top of the sacrificial layer.

High temperature resistance mask

An EMI/RFI shielding panel assembly is provided which is lightweight and easily and economically manufactured. The panel assembly of the invention may comprise one or more hinged members which snap together to form a closed frame having a filter media panel disposed therein, or may alternately comprise an integral frame having a filter media panel disposed therein or attached to the surface thereof.

EMI/RFI shielding vent and method of use

An EMI/RFI shielding gasket comprising a resilient elastomeric core enveloped with a fine, open format knit or braided wire mesh, and having a strip of pressure sensitive adhesive disposed lengthwise along a surface of the gasket. This strip of adhesive allows the gasket to be removably fastened to an enclosure, circumventing the need for a metal clip and thus making the gasket lighter and less expensive than conventional gaskets.
