Polycarbonate Diols and Polycarbonate-based Prepolymers

ETERNACOLL® polycarbonate diols (PCD) and ETERNATHANE® polycarbonate-based polyurethane prepolymers to produce extremely durable Polyurethane (PU)

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.

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!

Leverage the durability and weatherability of Polyurethane Wood Coatings

Polyurethane wood coatings are frequently exposed to harsh environments such as heat, UV, stains, scratch and abrasion.
For this, they have to be highly resistant to heat, UV, hydrolysis, chemicals, stains, exposure to scratch & abrasion or solvents. However, it is not easy to develop a durable Polyurethane wood coating without having to compromise on flexibility.
To cope with this, UBE has developed Eternacoll® Polycarbonate Diols, specific raw materials for Polyurethane that bring best-in-class durability, excellent weatherability and tunable balance between hardness and softness to wood coatings.
