The efficacy of guayule resin as a pesticide
Bioresource Technology, 1991Abstract Researchers from the United States are evaluating the nonrubber-producing extract (resin) of the guayule bush (Parthenium argentatum Gray) as a potential wood protectant against marine and terrestrial wood-destroying organisms in Panama. Wood treated with guayule resin was not attacked, or only lightly attacked, by limnorians (crustacean ...

Journal of Materials in Civil Engineering, 2023 Guayule resin was investigated through mixture to assess its role in the field performance. For performance comparisons, conventional asphalt, neat guayule, asphalt-rubber-guayule, and guayule-rubber binders were implied.

Guayule resin in amine—epoxy strippable coatings
Bioresource Technology, 1991Abstract The use of guayule coproducts as plasticizer/ adhesive modifiers in high-performance epoxy resin coatings was investigated. An amine curing agent, Jeffamine D-400, was employed to affect crosslinking. Epoxy resin coatings with and without guayule modification were applied to treated and untreated steel and aluminum panels for performance ...

The leachability of guayule resin from treated wood
Industrial Crops and Products, 1993Abstract Field evaluation has shown that guayule resin has potential as a protectant for wood against damage by terrestrial wood-destroying organisms. When used in this capacity, it is essential to know whether the resin migrates from the wood, as a contaminant, into the natural environment.

Cutting height effects on guayule latex, rubber, and resin yields
Industrial Crops and Products, 2010 Abstract Guayule (Parthenium argentatum Gray) is a perennial shrub native to the Chihuahuan Desert. While guayule traditionally has been cultivated for rubber, more recently it is being cultivated for its hypoallergenic latex. Other uses including termite resistant wood products and as an energy source have also been identified.

Degradative Effects of Guayule Resin on Natural Rubber. II. Kinetic Studies
Rubber Chemistry and Technology, 1982 Abstract Qualitative studies reported earlier and the kinetic studies reported here indicate that the unsaturated fatty acids in guayule resin are primarily responsible for the ability of guayule resin to accelerate the oxidative degradation of natural rubber.

Ultrafiltration of Guayule Resin
Journal of Membrane Science, 1995Abstract The ability of ultrafiltration membranes to effect a separation of the volatle essential oil fraction of guayule resin from other volatile constituents is experimentally demonstrated. For a methanol extraction of guayule resin, 200 and 500 molecular weight cut-off cellulose triacetate ultrafiltration membranes produced a permeate rich in ...

Resources, Conservation and Recycling, 2020 This research seeks to interpret the component analysis of an innovative bio-asphalt binder using guayule resin in addition to crumb rubber modifier (CRM) at high concentrations. Such asphalt modification aims to minimize the dependency on virgin asphalt

Gravimetric Analysis for Determining the Resin and Rubber Content of Guayule
Rubber Chemistry and Technology, 1983 Abstract The method presented provides a fast and sufficiently accurate method for determining the resin and rubber contents of guayule. Although it does not provide definitive or “absolute” values that presumably can be obtained with sophisticated instrumentation, it is well suited for agronomic developmental studies at the field station level.

Improved methods for extraction and quantification of resin and rubber from guayule
Industrial Crops and Products, 2009Abstract Guayule, a shrub native to the Chihuahuan desert, is a natural source of high quality, hypoallergenic rubber. Unlike rubber trees that produce rubber in laticifers, the rubber in guayule is produced in parenchyma cells of the bark tissue of stems and roots.
