Mont Clay Desiccants Principle They appear as gray or gray-red irregular granules. After being filtered among original mine of Mont stone, they are innoxious, environmental, biodegradable. They absorb water physically. Their capacity of moisture-absorption is stronger than other kinds of desiccants. Moreover, they are fit for vacuumized products. And the contents of heavy metal is lower than the standard of ROHS in EU and GP in Sony. Applications Be widely applied for dehumidification of the computer equipments, sophisticated machinery, optical glass instruments, test for semiconductor products encapsulation semiconductor products and electronic products. Criteria Meets international standard specifications such as MIL-D-3464E(US), JIS Z 0701 (Japan) and DIN 55473 (Germany).
