Weatherability of bio-based versus fossil-based polyurethane coatings “2279

HIGHLIGHTS

SUMMARY

    As the weathering degradation of PU top-coats was assessed more critically, the build-up of hydrophilic moieties during coating degradation promoted the absorption of water, thus leading to the formation of blisters on the coating surfaces after alternating dry and wet environments. The wahave differentPUD drying mechanisms and consequently different coating compared terborne coatings have different drying mechanisms and structures consequently different to PU coatings, resulting in relatively lower hardness and mechanical properties. coating structures compared to PU coatings, resulting in relatively lower hardness and For original non-exposed coatings, the hydrophobicity was . . .
