Product name STABiO™
Product description 1,5-Pentamethylene diisocyanate (PDI™) and polyisocyanate curing agent
Characteristics 1. High reactivity compared to 1,6-Hexamethylene diisocyanate (HDI)
2. Improves chemical resistance, gloss and abrasion resistance for paints and adhesives
3. Non-yellowing
4. 70% biomass (PDI™)
Main applications Automotive and plastic coatings, adhesives, etc.

With STABiO™, Mitsui Chemicals has developed the world’s first plant-derived isocyanate PDI™ and polyisocyanate curing agent using this. STABiO™ is used in paints and adhesive products, granting chemical resistance, abrasion resistance and gloss to a level not found with conventional polyurethane materials.

The high reactivity of STABiO™ allows for curing at lower temperatures and shorter times, leading to increased energy efficiency. Being plant-derived also makes the material environmentally friendly. Development is now advancing for new applications to create materials with unique textures, including a product with lightweight but strong transparent and a gel with unique softness.

Going forward, Mitsui Chemicals aims to use STABiO™ for further contributions to society by accelerating the development of new uses with a focus on its Mobility, Health Care and Food & Packaging business sectors.
