storage stability
desmodur rfe must be stored in a sealed container. whenever product is transferred from one container to another, moisture (including air moisture) must be prevented from entering. therefore, when small quantities of product are to be used regularly, they should not be taken from large shipping containers but from specially designed bottles of appropriate size.
in addition to the original container, twist cans made of aluminum or glass are particularly suitable for storing deslmodu rfe. suitable lids include screw caps with sealing gaskets. gaskets made of materials that release alkaline substances are not suitable.
crystals will form when the product is stored at low temperatures, but when heated slowly (to room temperature) the crystals will dissolve.

product safety
desmolds are composed of polyisocyanate and ethyl acetate. the former has low volatility, while the latter is volatile and flammable. therefore, precautions appropriate for use with flammable organic solvents must be taken. fog generated when working with adhesives containing desmodul rfe must be removed using an exhaust fan to ensure that there is no risk of inhalation (see safety data sheet for details).

compatibility
solvents that can be used to dilute desmodu rfe include: methyl acetate, ethyl acetate, acetone, methyl ethyl ketone and toluene. all these solvents must be free of water and alcohol.

purpose
properly formulated two-component adhesives have a limited pot life after adding desmodul rfe and must therefore be used before expiration. the above pot life depends not only on the polymer content of the adhesive, but also on other ingredients such as resins, antioxidants and solvents.
after the pot life expires, which typically lasts from a few hours to a working day, the adhesive becomes increasingly difficult to work with, its viscosity rises rapidly, and the formulation eventually gels irreversibly.
