Presenters Name: Laurence Teachout

Employment Title: Senior Technical Director

Company: Behr Paints

Biography: Larry started in the coatings industry with Flint Ink in 1988 after having graduated with BS in Chemistry from the University of Michigan. In 1989 while at Flint Ink he developed the industry’s’ first zero VOC non-hydrocarbon oil-based printing ink system using soybean oils. Larry earned a Master Degree in Polymers and Coatings from Eastern Michigan University in 1992. Over the years he has developed polysiloxane emulsions, aerospace and automotive polyurethane topcoats, epoxy primers, and colorant dispersions. He has worked for such companies as Pratt & Lambert and Deft Coatings. During this time Larry developed IR reflective and radar evasive coatings, fluorinated topcoats, and direct to metal coatings for Boeing, Lockheed, and Raytheon. In 2005 Larry was granted a patent for the development of a zero VOC direct to metal fluorinated topcoat with anti-corrosive properties based on Praseodymium Oxide to replace strontium chromate pretreatment of metals, as well as eliminating the need for primers. In 2005 he moved on to Behr Paints where he is currently is working as Senior Technical Director. Larry earned a Master Degree in Business Administration from California State University – Fullerton in 2008. He is a past president of the Los Angeles Society or Coatings Technology.  He was on the Board of Directors and served as Technical Chairman for the Western Coatings Symposium from 2003 until 2022.

Presentation Title:  Proper Colorant Formulation to Improve Properties of Tinted Decorative Paints

Presentation Abstract: There are many commercially available colorant systems used to tint POS and in-plant decorative paint bases. Most paint companies choose their colorant systems based on such factors as cost, yet never consider the impact the colorants will have on their tinted paints. However, these colorant systems have a significant detrimental impact on the performance properties of the paint bases they are used in. Properties such as surfactant leaching, blocking, scrub resistant, viscosity drop, stain resistance, corrosion resistance, dirt pick up, and many more. This results in significant use of resources in R&D as well as adding costs to the un-tinted paint bases.

In this presentation, we will show how colorants can be formulated to “improve” all the paint properties listed above when tinted into the paint base versus the un-tinted paint. This new system is also viscosity stable, has no syneresis, and eliminates mold growth in tint machines as well as painted exterior surfaces via use of technology from military and aerospace applications. This new colorant system can be used to match all commercially available colorant systems, so to allow for pour over the top of the older colorants and is cost neutral to older colorant system designs, and allows for reduction in raw material cost for paint bases.
