The Emulan grades are emulsifiers for the preparation of stable oil-in-water and water-in-oil emulsions.
Some of the Emulan grades are also suitable for making or stabilizing water-based dispersions; such as wax, polymer, and rubber dispersions, which are used for impregnating, lubricating, cleaning, polishing, protecting surfaces, or preventing dust.
The choice of the right emulsifier is extremely important for producing a stable emulsion.
The Emulan grades emulsifying performance and range of applications are determined by the nature of the hydrophilic and lipophilic parts of its molecules.
Oil-in-water emulsions are usually obtained if the hydrophilic character predominates and water-in-oil emulsions if the lipophilic character is predominant.
Storage of Emulan grades:
a) The Emulan types should be stored in their original packaging, which should be kept tightly sealed, in a dry place.
Storerooms must not be overheated.
b) Avoid a humid environment, because the products are hygroscopic and, being readily soluble in water, absorb moisture immediately.
For this reason, it is advisable to reseal drums tightly without delay each time material is taken from them.
c) The congealing points of the Emulan types must be taken into consideration when determining the storage temperature.
d) The Emulan types can become slightly cloudy if they are stored at low temperatures, but this has no effect on the product properties.
The cloudiness can be reversed at 50 – 60 °C.
e) Product that has solidified or that shows signs of precipitation should be heated to 50 – 70 °C and homogenized before use.
f) Product in drums that has solidified or that shows signs of precipitation should be melted or heated gently in a heating cabinet or heated chamber; the temperature should not exceed 50 – 70 °C, depending on the particular congealing or melting point.
This also applies if electric drum heaters are used.
Internal electrical elements are unsuitable for heating owing to the high heat load in some places.
g) If the Emulan types are stored in heated tanks at 50 – 70 °C (depending on the particular congealing or melting point), care must be taken to ensure that they do not come into contact with air (blanket with nitrogen).
Constant gentle stirring prevents them from overheating or becoming discoloured as a result of prolonged contact with the heating elements or external heating jacket.
h) Emulan OG and TO 40 Flakes should be stored in a dry place at a temperature not exceeding 25 – 30 °C.
Shelf life of Emulan grades:
The Emulan types have a shelf-life of at least 24 months, provided they are stored in their original packaging and kept tightly sealed.
