Jade 454 is a moderate Acetic acid emitter. It has been shown to fall in the acidic range for pH before and after aging. In aging tests, Jade 454 has been shown to emit Toluene, water, Dichloromethane, 2-ethoxy ethanol, and 2-ethoxy ethyl acetate. (Down et al 1996). Enclosures prepared with off-gassing materials, especially when large quantities of the materials are used, should be allowed to dry for three to four weeks before being used to enclose sensitive objects (Tétreault 2017).
