The vapour pressure, between the specific temperature limits, can be calculated
using the Antoine equation:
log10P+A - B where P is the vapour pressure in kPa and T is the temperature in 潞C.

Hexylene glycol is used as a coupling agent in the manufacture of hydraulic
Applications
fluids, industrial cleaning compounds, soluble oils and dry cleaning soaps. In
latex paints, hexylene glycol is a valuable and versatile additive; it aids
coalescence, promotes levelling and smoothness of films, enhances film
integrity and preserves freeze-thaw resistance. Solvent uses for hexylene
glycol include the preparation of dyes, and synthetic resin-base- flash-dry and
steamset inks. It also functions as a moistening and softening agent for
composition cork, casein, leather, paper and textile fibres, and as a wetting or
dispersing agent in polishes and cleaners. Other applications for hexylene
glycol include its use as an ingredient in grinding and extrusion aids and as a
solvent palsticiser in surface coatings.
Provided proper storage and handling precautions are taken we would expect
Storage and
hexylene glycol to be stable for at least 12 months.
handling
Advice on storage and handling may be obtained from your local Shell
Chemicals company. Hexylene glycol is available from Shell in bulk and
drums; details available on request.
Hexylene glycol is irritating to the eyes and skin.
