Sometimes when Sherwin-Williams develops and launches coatings to address specific market needs, down the road we find other markets can benefit from those product attributes.Â Thatâ€™s what happened with a rugged glass flake-reinforced amine epoxy coating and lining system that was originally intended for the demanding requirements of the marine and petrochemical markets.
One of our customers, a metropolitan sewerage district, could no longer rely on spot maintenance of its final clarifierâ€™s inner drum and rake arms. Working with our field sales organization, the MSD of Madison, Wisc., learned about a new technology â€“ Sher-Glass â€“ that was prized in petro and marine applications for its low permeability, basically a thin-film system with the same performance as a high-build system.
The glass flake component of the coating, which functions like armor but is lightweight, produces a more cohesive, durable film with enhanced resistance to abrasion and chemicals.Â Another plus: the superior edge retention so crucial to dealing effectively with the numerous angle welds, edges and seams of a rake arm assembly.
Joe Lynch, senior maintenance supervisor of Madison MSD, had a simple need at the Nine Springs Wastewater Treatment Plant â€“ a long-term approach to asset protection using a durable coating his own people could maintain without specialized plural component equipment or hazmat gear.Â Itâ€™s worked so well that heâ€™s using it again this summer on two additional rake arm assemblies.Â Read the full story in the current issue of Water & Wastes Digest.
