Abstract
An enclosure for providing both a moisture free and particle free environment is disclosed. A portion of the inner surface of the enclosure, that comprises an electronic device sealed in a container, is coated with a pressure sensitive adhesive comprising 4-40 percent, by volume, of a solid desiccant. The preferred adhesive is a silicone pressure sensitive adhesive and the preferred desiccant is zeolite.
