Sherwin-Williams Launches Fast Throughput Polyurethane Pipe Coatings and Linings
Poly-Cote™ polyurethanes provide chemical resistance and smooth finish
CLEVELAND (August 7, 2014) – Sherwin-Williams Protective and Marine Coatings has introduced a line of fast drying, high build, solvent-free polyurethanes for corrosion protection for the water conveyance piping market. The chemical and abrasion-resistant Poly-Cote™ 110 Fast Set, Poly-Cote™ 110 Rapid Set, Poly-Cote™ 115 and Poly-Cote™ 115FR provide a smooth, glossy finish and offer the hydrophobic properties of an epoxy while maintaining the durability, flexibility and fast cure times of a urethane. All products are NSF certified up to 250 mils.
The performance characteristics of the Poly-Cote line exceed the minimum requirements of AWWA C222-08, Polyurethane Coatings for the Interior and Exterior of Steel Water Pipe and Fittings. They provide optimal film build and aesthetic properties, and have a wide range of acceptable dry film thicknesses (DFT). Epoxy DFT ranges are commonly 16-50 mils, whereas the Poly-Cote products are 20-500 mils DFT for non-potable water applications and 20-250 mils DFT for potable water applications.
"The Poly-Cote line of products is engineered for production applications where fast cure times and excellent application characteristics are crucial," said Kevin Morris, water and wastewater market director, Sherwin-Williams Protective and Marine Coatings. "Required coating thickness can be achieved in one coat – even on seams, welds and rivets – allowing the asset to quickly return to service."
Poly-Cote 110 Fast Set is a polyurethane coating formulated for exterior diameter pipe applications, and has an industry-leading dry-to-handle time of 5-10 minutes. It can be applied via plural-component proportioning equipment with direct impingement mixing. Poly-Cote 110 Rapid Set is designed for interior diameter pipe applications, and provides a dry-to-handle time of 20-25 minutes. Its smooth finish is engineered for pipes to achieve better water transfer.
Poly-Cote 115 is a flexible polyurethane coating developed for small fittings, elbows, valves and other tight work spaces, and provides a 24-hour recoat window. Convenient for the field, Poly-Cote 115FR comes in an easy-to-use kit for coating welds and damage repairs. It can be applied by hand to both exterior coating and interior lining systems.Sherwin-Williams is a global protective and marine coatings company that delivers smarter asset protection and unmatched service and specification support to its customers from 4,000 locations worldwide.
