The NWSCT is planning IN-PERSON meetings for the current
2024-2025 meeting season.
Meetings are typically held the second Tuesday every month through April.

The February TopGolf event has been postponed (due to the inclement frigid weather) and it will be rescheduled in the near future.


April Meeting

Tuesday, April 8th

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 2025-2026 season. The meeting is being held on Tuesday, April 8th, 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 $30 for members and $35 for non-members. Registration must be made by/before Thursday, April 3rd.

There will be two (2) presentations titled, "Make polyurethanes without isocyanates? What are the possibilities?" presented by Dean C. Webster, Jingbo Wu, Alan Ekin, Ivan Hevus and "Hybrid Fluoropolymer Coatings" presented by Mark Rigel Ali, Eugene Caldona.

Abstracts: Polyurethanes are a high-performance class of polymer materials and are valued for their toughness, abrasion resistance, adhesion, and durability. Two-component polyurethanes can be applied under a wide variety of conditions and rapidly cure at ambient temperatures to a solid coating film. Due to potential health hazards of handling isocyanates, there has been growing interest in finding alternative ways to make polyurethane materials without exposing the end user to isocyanates. Some involve alternative urethane-forming reactions, but so far these have been found to have drawbacks. Another approach is that of alternative crosslinking polyurethanes (ACPU) where urethane groups are in the polymer backbone, but another chemistry is used for crosslinking. Epoxy functional polyurethanes are a potential ACPU and have been shown to have rapid cure speeds, which can enable curing at low temperatures. A good combination of properties such as hardness and flexibility along with good adhesion can be realized. A new and improved method to make epoxy functional polyurethanes has been discovered that has the potential to increase the commercial viability of these systems. We have also identified a method of making polyurethanes where isocyanate chemicals are not used in the process at all, and can lead to coating systems that cure rapidly under ambient conditions.

Fluoropolymer-based composite coatings with hybrid configurations offer an advanced solution for enhancing corrosion resistance, mechanical durability, and surface functionality in aggressive environments. This work explores the synergistic integration of functional additives into fluoropolymer matrices to optimize their protective performance. By incorporating inorganic and organic reinforcements, the hybrid coatings exhibit superior adhesion, electrochemical stability, and environmental resilience compared to conventional coatings. Our strategy involves integrating either network perfluorocyclobutyl (PFCB) or melt-processable poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) matrices with nanostructured fillers such as polydimethylsiloxane-modified silica, electrodeposited polyaniline, thienyl-functionalized silane, and organo-modified montmorillonite. These tailored hybrid formulations exhibit remarkable improvements in corrosion resistance, as measured via electrochemical assessment, and enhanced mechanical robustness through optimized filler-polymer interactions. The inclusion of hydrophobic and conductive polymeric phases contributes to both barrier protection and active electrochemical passivation, reducing water uptake and ionic transport at the metal-coating interface. Surface engineering approaches, including electropolymerization, silane coupling, and nanoclay functionalization, further improve coating-substrate adhesion, mitigating delamination risks under cyclic environmental stress. Wettability modifications, such as superhydrophobic structuring via fluoropolymer integration, also contribute to prolonged coating lifespan by minimizing corrosive electrolyte interaction. The thermomechanical performance of these coatings demonstrates significant improvements in hardness, flexibility, and thermal stability, making them suitable for demanding industrial applications. Our work provides a comprehensive framework for designing fluoropolymer-based hybrid coatings with tailored multifunctionality. By leveraging synergistic material interactions, these coatings offer a scalable and effective approach to improving long-term protection for metal substrates in various industrial applications.

January 2017 Winter Outing

This year the NWSCT broke new ground by hosting an event at Summit Brewing in St. Paul on January 10th. This event included a tour of their facility, dinner and of course beer sampling. It also allowed us to gain insight into a very important batch making process. Based on the turnout and enthusiasm for the event it will probably not be the last time that we host an event like this.

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.
