Guayule Coproducts: Emerging Technology in Industrial, Marine, and Peelable Coatings


Environmentally friendly, low VOC coatings were developed with the low molecular weight guayule rubber (LMWGR) and organic soluble resin (OSR) fractions obtained from Guayule (Parthenium argentatum gray) processing. Chlorinated maleinized guayule rubber (CMGR) was synthesized, characterized and formulated into commercial epoxy-polyester hybrid powder coatings as a multi-functional crosslinker/additive, and gave gloss reduction, surface texture, and corrosion resistance properties. The OSR isolated from the solvent-based guayule rubber extraction process was shown to be biologically active and blended into a marine coating formulation. Subsequently, the biologically active species of the OSR were isolated, characterized, and control release studies are currently in progress to determine leaching rates and long term biological activity. Finally, peelable coatings with excellent film properties were developed via use of the OSR in combination with Epon/Jeffamine intermediates. The peelable coatings offer ease of recoatability over conventional chemical or heat stripping techniques, and find potential applications in coating defense vehicles and other objects requiring temporary protection.
