Each segment below details how our isophorone integrates into customer processes, the compliance guidelines governing its use, recommended dosage strategies, and typical finished goods originating from these industry chains.

1. Production of Isophorone Diisocyanate (IPDI) for High-Performance Polyurethane Systems

Isophorone serves as the essential precursor for synthesizing IPDI, an aliphatic diisocyanate widely adopted in high-value polyurethane formulations such as automotive coatings, industrial clear coats, and weather-resistant adhesives. Our partners utilize it in dedicated isocyanate synthesis lines incorporating continuous reaction monitoring, feedstock purity controls, and strict hazard management throughout the process to achieve consistent downstream polymer quality.
