The NWSCT February meeting was held at the Tennant Company's Coatings Technology Center in Golden Valley.  Thanks to Tennant for hosting our meeting.  Tom Bekemeier from Dow Corning presented on "Next Generation Polysiloxane Coatings".  We had 25 people in attendance for the meeting, which included lunch, and welcomed two new members:  Chuck Gardner of Archway Sales and Kevin Rink of 3M.
 
Our March meeting will be held on Tuesday, March 12th at the 3M Innovation Center and will feature two technical speakers as well as an option to tour the 3M Innovation Center after our meeting.  This month's speakers are from Reichhold Chemical and 3M.  The Innovation Center is Building 278 on the 3M campus.  It is located at 2350 Minnehaha Avenue East;  St. Paul, MN  55144 (Map It).  The cost for the meeting is $15 for members and $20 for non-members if registration is made by Friday, March 8th ($20/$25 if registering later).  The meeting includes a luncheon buffet, technical presentations and an optional tour of 3M's Innovation Center.  
 

Registration is easy, just follow this link to register and pay for the meeting: Monthly Meeting Registration.  Please contact Wally Kesler (wkesler@valspar.com) if you plan to attend the meeting but will not be paying via PayPal so that we can get an accurate head count for lunch.  Please plan to arrive 5 minutes early so that we can prepare security badges for everyone.  Also, when registering, please confirm if you are going to attend the tour of the 3M Innovation Center at 2 pm.  This tour takes approximately 45 minutes.  

Jeff Danneman of Reichhold Chemical will present on "Alkyd Emulsions, a New Class of Low VOC Polymers".  Alkyd polymer chemistry provides a 1K self cross-linking binder based in part on bio-renewable resources.  The performance aspects of alkyds remain desirable but a change in carrier from solvent to water is necessitated by VOC restrictions.  As alkyds are polyester polymers, hydrolysis becomes an issue, particularly in architectural and maintenance coatings where several years of shelf life are required.  Several techniques are used to disperse alkyd polymers in water.  Fundamental differences in these will be described with an emphasis on the newest methodology introduced to the marketplace - Alkyd Latex. Some basic formulating guidelines, performance data and stability data will be presented.

Jeff Danneman received his bachelor's and master's degrees in Chemistry from the University of South Carolina.  He joined the coatings industry and FSCT in 1976 and has held positions with Glidden Paint, W.R. Grace and for the last 28 years, with Reichhold Chemical, where he holds the title Advanced Chemist Associate.  Mr. Danneman has spent the majority of his career in product development and technical service.  His development work includes polymers for water-reducible, high solids, UV cure, polyurea and alkyd latex coatings.   He holds patents for high solids architectural coatings, polyurea polymers and high performance traffic coatings.  His current focus is on formulating alkyd latex polymers for both architectural and industrial applications.

Lesbia Giron of 3M will present on the "Impact of properties on Coatings formulated with Ceramic Microspheres".  This study was conducted to determine the effect of Ceramic Microspheres in paint formulas as well as to determine the optimum amount of ceramic microspheres needed to produce a flat paint formulation that exhibits higher performance and quality.  The study also includes the effect of several Glass bubbles in a flat architectural paint.  The study will examine the impact of Ceramic Microspheres on Dispersibility, Scrub Resistance, Washability, Burnish Resistance and Gloss Control.

Lesbia Giron earned a B.S. in Chemical Engineering from the University of San Carlos, Guatemala City, Guatemala with an emphasis in Chemical Processes.  She has over 10 years of experience in research, development and formulation of solvent and water-based primers, inks and adhesives, with expertise in new product development and introduction of new technologies to worldwide customers.  She is a Senior Technical Service Engineer at 3M in the Advanced Materials Division, U.S. Paints & Coatings Laboratory. She is responsible for new product development, new applications and technical service with focus on ceramic microspheres, glass bubbles, and fluorochemicals.
