Abstract
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.
