Product name STABIO™
Product description 1,5-Pentamethylene diisocyanate (STABiO™ PDI™) and a polyisocyanate hardener made as a derivative of this
  1. High reactivity compared to 1,6-Hexamethylene diisocyanate (HDI), reducing curing time by approximately 25 percent
  2. Improves chemical resistance, gloss and abrasion resistance for paints and adhesives
  3. Non-yellowing
  4. 70% biomass (PDI™)
  5. In CO2-equivalent terms, reduces greenhouse gas emissions by approximately 20 percent (based on life cycle assessments of the derivative versus an existing product manufactured by Mitsui Chemicals)
Main applications Automotive and plastic coatings, adhesives, etc.

With STABiO™, Mitsui Chemicals has developed the world’s first bio-based isocyanate PDI™ and polyisocyanate hardener 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 bio-based also makes the material environmentally friendly. Development is now advancing for new applications that require materials with unique textures – including a product that is lightweight but strong and transparent, as well as a gel with unique softness.

Going forward, Mitsui Chemicals will work to popularize STABiO™ as it looks to help bring about a society that gets maximum use out of renewable resources.
