Protective coatings for heavy industrial and infrastructure applications must withstand the test of time. These coatings are under relentless pressure from environmental conditions and are often found in sensitive or hard-to-access locations where recoating must be minimized. Currently, fluoropolymers are the gold standard for these applications due to their ability to enable extreme durability. However, these resins do come with trade-offs  including high costs and growing regulatory pressure surrounding the use of polyfluorinated materials. To address these concerns, Eastman has developed novel polyester-based protective resin systems based on a unique monomer that showcase exceptional weathering and have the potential to match the performance of currently available fluoropolymers.

This presentation with showcase initial weathering data for these resins, as well as an analysis of the polymer linkages and modelling of polymer photo degradation to demonstrate why we believe these new resins are so highly weatherable.
