Overview

Isophorone Diisocyanate (IPDI) | CAS 4098-71-9 | Aliphatic Polyurethane Intermediate

Product Overview

Isophorone diisocyanate (IPDI) is a representative aliphatic diisocyanate used as a key building block in high-performance polyurethane systems. Compared with aromatic diisocyanates, IPDI offers superior weather resistance and non-yellowing properties.

Molecular Structure & Characteristics

IPDI features a cycloaliphatic backbone combined with reactive isocyanate groups, enabling controlled reactivity and balanced mechanical performance in polyurethane coatings, adhesives, and elastomers.

Physicochemical Properties

Appearance: Colorless to pale yellow liquid
Functionality: Diisocyanate
Moderate reactivity for formulation control
Excellent weather and UV resistance

Applications

Polyurethane Coatings: Automotive, industrial, and wood coatings.
Adhesives: High-performance bonding systems.
Elastomers: Durable polyurethane elastomer materials.
Specialty Materials: Outdoor and weather-resistant applications.

Market Insights & Growth Outlook

Demand for high-durability and non-yellowing polyurethane materials continues to drive steady growth of IPDI in global coatings and advanced material markets.

SYNVERTA provides stable chemical supply support for global markets and serves ongoing B2B procurement partnerships.
