Jade 403

Description

[Jade Adhesives, Chicago] A brand name for a white aqueous adhesive Emulsion containing Ethylene vinyl acetate (20/80) copolymer. Jade 403 may also contain small amounts of plasticizers, dispersion aids, defoamers and preservatives. Traces of Formaldehyde have been found (Down et al 1996). Jade 403N performed well among the six adhesives tested in the CCI Report No. 1603 on testing of polyvinyl acetate and acrylic adhesives (Down et al 1996).

Personal Risks

• The adhesive is not classified as hazardous.
• The residual monomer is considered toxic. Use in a well-ventilated area.
• Jade 403 SDS [1]

Collection Risks

Jade 403 is a low level Acetic acid emitter. It has been found to fall within an acceptable range for pH after aging. In dark aging tests, Jade 403 has been shown to emit Ethyl acetate, Methyl acetate, n-butanol, water, and dibutyl ether. In light aging tests, it emitted Acetaldehyde, ethyl acetate, methyl acetate, and water (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).

Physical and Chemical Properties

• Emulsion has 50% solids. Viscosity = 6000-7000 cps.
• Emulsion pH = 6.5-7.2 (manufacturer).
• Dried film swells in water, ethanol and toluene.

Working Properties

The Jade 403 emulsion may be applied with a brush, roller, or by extrusion. For proper viscosity and flow, it should be used at a room temperature of at least 72°F. The emulsion may be diluted with water. It should be stored between 60 and 100°F and not allowed to freeze.

Forms/Sizes

Emulsion is available in ½ pint, pint, quart, gallon, and 5-gallon containers.
