Color and Its Effects on Coating Performance: The Value of Clear Coats

Color and Its Effects on Coating Performance: The Value of Clear Coats
Available for download

To determine how colors change during weathering, ten non-leaded polyurethane colors were exposed to QUV accelerated weathering, Chicago outdoor exposure and Florida outdoor exposure. Color change, percent gloss retention and Aesthetic Ratings were made every 1000 hours in QUV up to 8000 hours, yearly in Chicago exposure for four years and yearly in Florida exposure for three years.

Color change, percent gloss retention and Aesthetic Ratings were made every 1000 hours in QUV up to 8000 hours, yearly in Chicago exposure for four years and yearly in Florida exposure for three years. Dramatic changes in Aesthetic Ratings revealed that some colors maintain aesthetics much longer than other colors. The same ten colors were also exposed with a clear coat topcoat. Using a clear coat improved aesthetic performance significantly and greatly reduced the differences in Aesthetic Ratings between the various colors.

Coating Failures on Painted Galvanized Mast Arms

Product Number: 41208-402-SG
Author: Paul Vinik, Richard A. Burgess
Publication Date: 2008

Galvanized mast arms support uncounted numbers of traffic signals and signage throughout the United States. The proportion of these that have a “duplex” coating system (both galvanizing and organic coatings) is unknown. However, the number is surely significant, and the number of coating system failures is also significant.

Benefits of Using Both SSPC & PDCA Standards in Project Specifications

Product Number: 41208-441-SG

This paper examines the authors successful experiences on some simple and very complex projects where both the coatings and environmental requirements were limited to a few pages. Being made up almost entirely of SSPC/NACE and PDCA standards that described “performance criteria” as opposed to being a prescriptive or proprietary type of specification defining what was to be used, when it was to be used and how it was to be done.

Current and future coating restrictions that reduce atmospheric emissions as well as the potential for the leaching of chemicals into drinking water systems are pushing tank owners and/or specifiers towards the use of 100% Solids by Volume (SBV) coatings. A majority of these high solids coatings whether epoxy, polyurethane, or polyurea, can or should be and in some instances must be, applied using Plural Component (PC) spray equipment.
