HEXAMETHYLENEDIAMINE Chemical compatibility with O-rings, rubbers, & plastics

Hexamethylenediamine (HMDA) is an organic compound with the formula C6H16N2. It is a colorless, crystalline solid with a slight amine odor. HMDA is primarily used as a precursor in the production of nylon 6,6 and other polyamides. It reacts with adipic acid to form the nylon polymer, which is known for its strength, elasticity, and resistance to wear and chemicals. HMDA is also used in the manufacture of coatings, adhesives, and elastomers. Handling HMDA requires caution as it can cause skin, eye, and respiratory irritation. Prolonged or repeated exposure may lead to more severe health effects, including liver and kidney damage. Proper storage and handling, including the use of personal protective equipment and good ventilation, are essential to prevent exposure. HMDA's role in the production of high-performance materials highlights its importance in the chemical and manufacturing industries.
