Bayer raw materials help polyurethane coatings with improved weatherability

Atlanta, April 4, 2014 — When evaluating coatings for industrial maintenance applications, asset protection is a top priority. Yet, methods for re-creating real-world conditions in the lab, such as accelerated weathering, do not necessarily predict performance in the field. This is due to the difficulty in simulating variables such as dirt pickup, air pollution, acid rain, wind-borne particle erosion and mildew.

Focusing on how the chemistry of a coating is broken down, such as through photo-oxidation and hydrolysis, creates a more realistic correlation between lab tests and field performance as it considers the effects on a binder’s chemistry, the coating’s formulation and weathering conditions.

With these testing methods, Bayer is able to develop polyurethane coatings that are among the most versatile topcoats available in today’s market and can be formulated to offer years of protection for highly valued assets.

Todd Williams, corrosion manager, Coatings, Adhesives & Specialties, Bayer MaterialScience LLC, will present “Correlation between QUV-A and long-term Florida weathering: Formulation and structure / property relationships in polyurethane coatings” at 5 p.m., April 7, during the American Coatings Show and Conference in Atlanta. His discussion includes performance results for several coating formulations after examining the binder chemistry effects on fluorescent artificial (QUV-A) and South Florida weathering test methods.

“One of the key findings of the study is that the selection of a quality polyol is the most critical formulation variable to influence long-term weathering of a two-component acrylic polyurethane,” Williams said.
