Formulating Polyurethane (PU) products that meet your needs is not simple!

Indeed, products that can withstand extreme conditions as well as guaranteeing durable high performance are not always easy to identify.

UBE polycarbonate diol ETERNACOLL® Technology enable to formulate unique, customizable polyurethane coatings, elastomers, adhesives and sealants which offer long lasting performance even after exposure to extreme environments.

Polycarbonate diol ETERNACOLL® offer greater stability, allowing polyurethanes to retain its initial properties over time.

This site will provide you with information on polycarbonate diols for polyurethane products, including case studies and downloads, product and industry news as well as everything you need to know about polyurethane technical performance, formulation and product selection.


In terms of durability, the Polyurethane produced from Polycarbonate diol ETERNACOLL® is superior to that produced from polyether-diol or polyester-diol.

Its exceptional properties include:

  • Increased adhesion to substrate
  • Outstanding water resistance
  • Excellent hydrolytic stability
  • Greater chemical & stain resistance
  • Higher thermal stability
  • Improved mechanical properties
  • Better gloss retention
  • Good scratch & abrasion resistance

Polycarbonate diol ETERNACOLL® are used for a wide range of polyurethane coatings, adhesives and elastomers.
