Physicochemical Indicators

Application   　Uses
　　 WANNATE ^® HMDI (4, 4'- 4,4'-Methylenebis(cyclohexyl isocyanate) ) is a dicyclohexyl aliphatic diisocyanate, appearing colorless or slightly yellowish, low viscosity liquid at room temperature, with a special odor.

WANNATE ^® HMDI As a raw material for producing polyurethane, it is suitable for producing polyurethanes with good light stability, weather resistance and excellent mechanical properties. It is especially suitable for producing elastomers, waterborne coatings, polyurethane dispersants and photocurable urethane-modified acrylates.  

Packaging Specifications
　　 200 kg Iron drum

Storage and Handling Precautions

WANNATE ^® HMDI It is a clear and transparent liquid. Due to its active chemical properties, it easily reacts with water to generate insoluble urea compounds and release carbon dioxide, causing drum swelling and increased viscosity. Therefore, during storage, it is necessary to ensure that the container is strictly dry and sealed and filled with dry nitrogen protection. Below 25 ℃ ， WANNATE ^® HMDI partial crystallization may occur and precipitate to the bottom of the container. In this case, first heat the product to 40 ~ 50 ℃ ，shake well before use.

Shelf Life

This product is sensitive to moisture. At 0~30℃ under cool and dry conditions, the shelf life of the product stored in the original sealed container is 9 months.
