Coating composition

摘要

Coating compositions containing components derived from the thermo-catalytic conversion of biomass are provided. The components derived from the thermo-catalytic conversion of biomass are useful in increasing the bond strength retention of such coating compositions to the surface of a substrate.

主权项

1. A coating composition, comprising a high molecular weight fraction of a biomass T-C oil, wherein the high molecular weight fraction comprises a non-hydrotreated portion and a portion that has been at least partially hydrotreated, and wherein:
i) the high molecular weight fraction of the biomass T-C oil is produced from the thermo-catalytic conversion of a biomass and has a boiling point of at least 650° F.; ii) at least about 10% of the carbon atoms of said high molecular weight fraction are functionalized with a functionalizing component selected from the group consisting of a hydrogen-bond donor moiety, a hydrogen-bond acceptor moiety, and combinations thereof; iii) the at least partially hydrotreated portion of the high molecular weight fraction has an oxygen content less than about 10 wt %; and iv) the non-hydrotreated portion of the high molecular weight fraction has an oxygen content less than about 20 wt %.
