April Meeting
Tuesday, April 7th
This is our Annual Education Symposium and features presentations from students at North Dakota State University's Department of Coatings and Polymeric Materials. The meeting will begin with an overview of current NWSCT business, including a vote for nominated executives for the NWSCT for the 2026-2027 season. The meeting is being held on Tuesday, April 7th, 11:30am-1:30pm at Sherwin Williams in Minneapolis, MN (1101 S 3rd St, Minneapolis, MN 55415 MAP) and will include lunch which the cost is $29 for members and $34 for non-members. Registration must be made by/before Thursday, April 2nd.
There will be two (2) presentations titled, "Autoxidation-Epoxy Curing Synergy for High-Performance Bio-Based Thermosets" presented by Mariia Usiichuk and "The Design of Ice-Resistant Coatings" presented by Dean C. Webster and team.
Abstracts:
The growing environmental and health concerns associated with petroleum-derived thermosets, particularly bisphenol A (BPA)-based epoxies, have driven the search for sustainable, high-performance alternatives from renewable resources. In this work, biobased dual-curing thermosets were developed using a soybean oil-based acrylic monomer (SBM), 2-glycidoxy-5-vinylanisole (GVA), and 2-ethylhexyl acrylate (2-EHA). The designed system combines epoxy-amine crosslinking and autoxidative curing, enabling controlled polymer network formation. A biobased curing agent, 5,5′-(1-Methylethylidene)bis[2-furanmethanamine], allows efficient epoxy-amine crosslinking and formation of highly crosslinked networks. The substantial presence of polyunsaturated fatty acid fragments in the SBM structure provides the potential for oxidative crosslinking, complementing the epoxy reaction pathway.
A series of formulations with varying epoxy-to-amine ratios was prepared to determine the optimal balance between the two curing mechanisms. Thermosets produced through the dual-curing route exhibit markedly improved mechanical strength and solvent resistance compared to those obtained via either curing mechanism alone. Optimization of the epoxy-to-amine ratio shows that a 1:0.8 stoichiometry provides the best balance of properties, yielding thermosets with a Young’s modulus of 1240 MPa and a storage modulus in the glassy region of 3030 MPa – values not achieved through a single-curing mechanism.
This study demonstrates that dual-curing strategies and targeted formulation design enable the engineering of high-performance thermoset coatings possessing enhanced mechanical and chemical durability, while preserving the advantages of renewable, bio-based components.
Ice accumulation on infrastructure creates significant operational and safety issues. Ice accumulation adds weight that can bring down trees and power lines. It can upset the balance of ships. And falling ice can create a safety hazard. Removal of ice can itself be hazardous and using deicing fluids can harm the environment. There are many approaches reported to coatings that can reduce the adhesion of ice. One important aspect is that the coating should be able to shed large areas of ice accumulation. To do so the coating needs to demonstrate low interfacial toughness (LIT) between the coating surface and the ice so that when a crack is initiated it can propagate. The coating should also be durable so that it can continue to function after multiple icing and deicing cycles. Our approach has been to start with a tough coating resin system and made modifications to reduce the adhesion of ice and introduce LIT behavior. In one system, we started with an epoxy-siloxane coating system and investigated the effect of adding silicone oils of differing composition on the ice releasing behavior. From the study a formulation was identified that had very low ice adhesion. Other resin systems can be modified in a similar fashion, but the specific oil composition that results in the best properties may be different. Overall, we have identified several different coating systems that have good ice release properties and good durability.

Annual Education Symposium Abstracts
Electrochemical Investigation of Polyester Powder Topcoats and Application to Magnesium-Rich Primers for Corrosion Protection Systems
Casey Orgon
Abstract
Environmental concerns in the coatings industry have led to strict regulation of the use of conventional solvents used in coatings formulations. Powder coating systems avoid this issue by fluidizing finely ground particles in air for efficient transfer to a substrate. Once cured, these coatings can provide high performance protection and have already proven themselves in many extreme environments. In partnership with Valspar and The United States Air Force, NDSU has begun research on powder coatings for corrosion protection. Electrochemical impedance spectroscopy has been used to assess barrier properties of polyester powder topcoats crosslinked by TGIC and Primid chemistries. In addition, the feasibility of applying powder topcoats to Mg-rich primers has been explored with promising results. Combining these coatings can provide a corrosion protection system with high barrier properties of the powder topcoat and cathodic protection by the Mg-rich primer.
Vanillin: A Biobased Crosslinker for Epoxy Thermoset Coatings
Alison Rohly
Abstract
With an increasing need for biobased replacements of petrochemical materials, lignin offers significant potential in strength, durability, cost, and functionality. Lignin can be depolymerized to form small molecular weight compounds, the most abundant being vanillin. Although little research has been done, vanillin offers great potential as a crosslinker in coatings systems due to its unique functionality. The current research is therefore focused at incorporating lignin-derived vanillin into epoxy thermoset systems as a biobased crosslinker.
