Webinar: An Accelerated Weathering Survey of Organic Yellow Pigments Dr. Brij Mohal, Vice President – Innovation and Technology

Register for June 4th Webinar 11am EDT


Performance expectations of high chromatic colorants, especially organic yellows have increased over the years along with the popularity of bright outdoor colors.  Pigment yellows with the following color index (CI numbers) including 3, 65, 74, 97, 110, 138, 155, 184 and 184/74 blend will be compared via Xenon arc accelerated weathering as colorants in commercial exterior bases with different levels of titanium dioxide (ultra-deep base and medium tint base).  Measurements discussed compare CieLAB, Delta E, and strength at 500, 1000, 1500, and 2000 hours in a Q-Sun Xe 3HS weathering incorporating ASTM G-155 Cycle 3; Standard Practice for Operating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials.

In addition, with the possible issues with certain pigment production the possible alternates with their pros and cons will be discussed.  It is worth noting that each of these pigments possesses a firm place in industry because they satisfy some need which exists in the market.  The importance of this comparison is to assist the user in determining the proper yellow pigment for their application.  The value of these pigments will also be compared with respect to relative cost and weathering performance.
