Chemline (St. Louis, Missouri) is now offering an advanced line of rapid-curing polyurethane coating systems specifically engineered for water pipelines, both potable and wastewater.
The unique chemistry of Chemline’s coatings provides long-term protection against corrosion, abrasion, impact, and other mechanical damage in a highly challenging environment, the company says.
Chemline’s coatings have been formulated to offer strong flexibility to withstand the movement associated with the installation of pipelines, including nearly constant submersion in water with varying temperature, alkalinity, pH, mineral content, and/or dissolved solids.
The 100% solids polyurethane systems meet stringent volatile organic compound (VOC) regulations, the company says, and they are one of very few coatings with an acceptable extractable and leachable profile for potable water. In fact, these coatings have no impact on the taste of water.
The coatings build quickly and smoothly to desired thickness, Chemline says. Additionally, cure times are fast—making them ideal for original equipment manufacturers who want to boost throughput.
Key features of the coatings include:
• 100% solids/zero VOCs, meaning no coal tar, styrene, or solvents
• Durable, high adhesion for long-term protection
• No primer requirement on properly prepared metal
• Full compliance with AWWA C-222-08 specification and ANSI/NSF Standard 61
