Sherwin-Williams Protective & Marine Coatings has released its Zinc Clad 4100, a high-solids coating featuring recoat times as short as 30 minutes.
This shortened timeframe allows for accelerated shop throughput, enhanced project schedules, and fast project turnarounds. To provide further efficiency, the three-component, organic zinc-rich epoxy primer eliminates the need for sweat-in time.
The packaging of the coating also allows applicators to mix components directly in the Part A container for faster and more accurate mixing, the company explains.
Performance Characteristics
Designed for use over properly prepared blasted steel, the organic zinc-rich primer offers strong application properties and performance in the field. For example, the coating provides cathodic protection to reduce corrosion potential in the event of the steel substrate being exposed due to coating damage. In addition, the coating exhibits self-healing properties if it becomes damaged.
“Zinc Clad 4100 answers our customers’ need for a high-solids, organic, zinc-rich epoxy that enables productivity improvements across and array of shop and field applications,” says Tim McDonough, marketing director for the company's products and services business.
Wide Application Range
The coating enables more application opportunities for bridge, highway, and structural steel markets due to its performance characteristics. For example, it meets Class B requirements for slip coefficient and creep resistance for use in slip-critical bolted connections in all U.S. states. The coating also meets performance requirements for use on highway bridge steel in the northeast United States.
The coating is suitable for a wide range of shop and field applications, the company explains, including bridge structures, stadiums, steel fabrication shops, piping, barges and ships, drilling rigs, and refineries.
