PRODUCT CHARACTER-
ISTICS
COSMONATE PH is highly purified monomeric MDI. It takes the form of white crystals at room temperature and appears as a clear, colorless liquid when melted. Monomeric MDI exists as a mixture of 3 isomers: 2,2- , 2,4- , and 4,4-MDI, with each monomer having two reactive isocyanate groups. MDI has particularly strong resistance to discoloration, and is applied as a stabilizer against high temperatures and ultraviolet light.

HANDLING AND STORAGE
Careful attention must be paid when handling this product after it has been held in storage, as it may spontaneously generate cyclohexane insoluble in quantities varying with storage time and temperature. It is therefore recommended that this product be used as soon afterdelivery as possible.
Generation of cyclohexane insoluble occurs most readily at temperatures slightly below the melting point of COSMONATE PH (30~38˚C) and at temperatures above 50˚C, and is reduced at temperatures slightly above the melting point (40~45˚C), as well as at cold temperatures below 0˚C (refer to Figures 1 and 2).
