Polycarbonate Diols (PCD) for Durable Polyurethane Coatings

ETERNACOLL® polycarbonate diols (PCD) and ETERNATHANE® polycarbonate-based polyurethane prepolymers are used for a wide range of Polyurethane Coatings, providing extreme durability and high performance to the final polymer. These products offer customizable possibilities for superior & long-term retention of designed performances.

Polycarbonate Diols and Polycarbonate-based Prepolymers

Durable Polyurethane Coatings

Polycarbonate Diols (PCD) and Polycarbonate-based polyurethane Prepolymers are used for a wide range of polyurethane-based coating formulations, providing extreme durability and a high performance to the final polymer. 

These products offer customizable possibilities for superior & long-term retention of designed performances, with no modification of initial properties after being exposed in harsh environments.

Ask for a sample

The Polyurethane produced from Polycarbonate Diols or
Polycarbonate-based Polyurethane prepolymers is superior
to the one
produced from polyether-diol or polyester-diol in terms of durability.

Why? Because it can provide outstanding performances, such as:
  • Excellent hydrolytic stability
  • Increased chemical and stain resistance
  • High thermal stability / lower yellowish
  • Improved mechanical properties
  • Better retention of gloss
  • Very good scratch & abrasion resistance, and others!
