[2] Aliphatic diisocyanates are used, not in the production of polyurethane foam, but in special applications, such as enamel coatings which are resistant to abrasion and degradation from ultraviolet light.

This distinctive attribute proves advantageous in processing low-viscosity prepolymers, resulting in a notably reduced residual content of monomeric diisocyanate.

The presence of methyl groups linked to the cyclohexane ring broadens IPDI's compatibility with resins and solvents.

The inherent cycloaliphatic ring confers heightened rigidity and a notably elevated glass transition temperature to IPDI-based products.

Semi-finished products like NCO-terminated prepolymers exhibit a low tendency to crystallize, remaining in a liquid state and facilitating easy processing.
