International Paint has launched a series of fast-cure zinc silicate coatings that purportedly offer dramatic productivity gains to fabrication customers.
The Interzinc 22 Series can be recoated in less than five hours, which can cut overall finishing time by more than a full day when using a typical three-coat zinc/epoxy/polyurethane system, the company says.
“The technology used in the Interzinc 22 Series results in much faster recoat times than conventional zinc silicates,” said Ian Fletcher, Worldwide Oil and Gas Market Manager. “This allows faster throughput of coated steel, greatly enhancing productivity.”
With four levels of zinc dust, the Interzinc 22 products offer the flexibility to tailor specifications to a variety of standards and customers’ end-use requirements, Fletcher said.
The series is available with 85%, 80%, 77% or 65% zinc dust content, all with low (<100 parts per million) lead content. The 85% and 80% products are compliant with the Norsok M501 standard, allowing offshore use; the 85% product is also Class B Slip Coefficient approved for use on slip-critical surfaces.
Feedback from customers has been positive, says International Paint, the world’s biggest producer of protective coatings for steel structures used in the power generation, oil and gas, mining and water industries, and for architectural infrastructure and bridges.
