What Are Aliphatic Diisocyanates?

Aliphatic diisocyanates are a class of isocyanate compounds, which contain two isocyanate groups. Unlike aromatic diisocyanates, they are characterized by their aliphatic chains, resulting in lower volatility and enhanced stability. This makes them less toxic and more suitable for applications that require high durability and resistance to weathering.

Key Properties

One of the standout features of aliphatic diisocyanates is their ability to cross-link with polyols to create robust polyurethane systems. These systems offer excellent mechanical properties, resistance to UV light, and good thermal stability. Consequently, materials created using these diisocyanates exhibit superior performance in demanding environments.

Common Examples

Some widely used types include hexamethylene diisocyanate (HDI) and isophorone diisocyanate (IPDI). HDI, for instance, is often used in automotive coatings, elastomers, and adhesives. IPDI is favored in applications requiring transparency, such as in clear coatings.

Applications in Industry
