Hexamethylene Diisocyanate

1. Definition Hexamethylene Diisocyanate:

Hexamethylene Diisocyanate (HDI) is a chemical compound that is commonly used in the production of polyurethane coatings, adhesives, sealants, and elastomers. It is a colorless to pale yellow liquid with a pungent odor.

2. Use:

HDI is primarily used as a crosslinking agent in the manufacturing of polyurethane products. It reacts with polyols to form polyurethane polymers, which are then used in a wide range of applications, including automotive coatings, industrial coatings, and furniture finishes.

3. Usage Hexamethylene Diisocyanate:

When using products containing HDI, it is important to take precautions to minimize exposure to the chemical. This includes wearing appropriate personal protective equipment, such as gloves, goggles, and a respirator, to prevent skin contact, eye contact, and inhalation of HDI vapors. It is also important to work in a well-ventilated area to reduce the risk of exposure.
