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.
March Meeting
Tuesday, March 11th
The meeting on Tuesday, March 11th (11:30am-1:30pm) will be held at Sika MBCC US LLC in Shakopee, MN (889 Valley Park Dr S, Shakopee, MN 55379 MAP). Bonnie Piro of Sudarshan North America, Inc. will present, "The Impact Pigment Finishing Choices Have ON Coatings Formulations". The meeting will involve a short business update, lunch and the technical talk and will cost $30 for NWSCT members and $35 for non-members. Registration must be made by/before Friday, March 7th.
Abstract: Pigments, whether organic or inorganic, are a very important part of the colorant world. They bring color to the final article. The color is designed to achieve several outcomes – catch the eye of a shopper, identify the brand of the product, provide technical properties to the end product for its environment and many more. It is these technical properties that can be “shifted” by the choice of finishing technique or process selected for that pigment product.
About 75% of a pigment’s technical properties are achieved by chemistry alone. Properties such as heat stability, weather fastness and chemical resistance are derived from the chemistry of the pigment. The remaining 25% of the technical properties are obtained by the choice of the finishing. Finishing of a pigment encompasses both chemical and mechanical processes that are put on the pigment once the crystal is formed. The choices selected are made with the end application or sub-application in mind. Is this pigment to be used in coatings, plastic or ink formulations? If it is coating, will it be water, solvent or powder? If a solvent-based coating, will it be used for industrial or higher end automotive? The answer to these questions drives the pigment formulator towards a certain set of processing steps. However, this is not to say that a pigment developed for one application cannot be used in another application because they can. The finishing steps will provide different outcomes in the formulation.
This presentation will provide examples of how the finishing steps can shift the performance within the same chemistry pigment.
Speaker Bio:
Bonnie Piro – Technical Service and Marketing Manager; Sudarshan North America, Inc. - Education: B.S Chemical Engineering – Drexel University, 1989; M.S. Engineering Management – Drexel University, 1992
I have been with Sudarshan for 7 years working with both the US sales team and with our labs in India to provide the technical support needed. In addition, I head up the product promotion and customer learning and idea generation via our monthly webinar series – Pigment 101 and our Color of the Month series. Prior to Sudarshan, I was with Axalta Coating Systems (formally DuPont) for 30 years and all of that time was in the pigment/colorant area – replacement, dispersion formulation and color matching and design.

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.
