Solvent-Free Coating Using Maco Bio-Based Reactive Diluent, Ryder James
Solvent-Free Coating Using Maco Bio-Based Reactive Diluent, Ryder James
Williams Honors College, Honors Research Projects
The project performed utilizes methacrylated cardanol (MACO) and a linseed oil resin to test how different weight percentages of MACO affect coating performance. MACO is synthesized from a phenolic lipid extracted from cashew nut shells, which are a cashew industry waste product. Not only does it utilize a waste product, but being a bio-based reactive diluent means it can replace the use of volatile organic solvents that are harmful to both humans and the environment. Weight percentage samples of 0%, 10%, 20%, 30%, and 40% were used. Coatings were applied using a 6-mil drawn down bar, with samples being prepared …

Synthesis Of Polyurethane From Sustainable Sources, Jovan Jevric
Williams Honors College, Honors Research Projects
The most common method of polyurethanes involves a reaction between various petroleum-based isocyanates and a polyol along with a catalyst; all of which have a negative impact on environmental and human health. The objective of this research project is to eliminate or mitigate the risks and hazards associated with the production and degradation of polyurethane. Hexamethylene diisocyanate isocyanurates (3HDI) are one of the most common isocyanates used in the polyurethane processing industry. 3HDI contains numerous toxins, and it has a negative impact on the environment and human health1. It has been found that there are other compounds that …
Effects Of Corrosion Inhibitor On The Corrosion Behavior Of Low Carbon Steel In Co2 Environment, Michael Harris
Effects Of Corrosion Inhibitor On The Corrosion Behavior Of Low Carbon Steel In Co2 Environment, Michael Harris
Williams Honors College, Honors Research Projects
The effectiveness of Benzalkonium chloride (C14) as a corrosion inhibitor for mild steel in an aqueous CO2 environment was studied for dual use. It is a known biocide and currently untested corrosion inhibitor. Potentiodynamic polarization was used to determine the anodic and cathodic reaction kinetics through analysis of the potentiodynamic curves and the corrosion current densities. Electrochemical impedance spectroscopy (EIS) was utilized to analyze the surface characteristics through analysis of the Nyquist and Bode plots. C1010 and C1018 mild steel were tested in a 200mL jacketed Gamery cell, and purged with CO2 (99.9%). Temperature effects were studied and …
