Aliphatic Diisocyanates and Transparency

Aliphatic isocyanates, as well as possessing superior light stability have also been seen to show increased phase separation behaviour over aromatic isocyanates. The T s of systems based upon HDI, H12MDI and IPDI are lower than that of TDI and MDI systems. This is attributed to stronger hydrogen bonding being obtained in the hard block domains. [Pg.59]
