Polycarbonate Diols (PCD) are used for a wide range of polyurethane-based coating formulations
, providing an 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 PCD 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!
