Description

Zinc Sulfamate CAS NO 13770-90-6 is an inorganic salt primarily valued for its role as a highly soluble and efficient source of zinc ions in specialized electroplating and metal finishing processes. Its key advantage lies in its ability to produce smooth, fine-grained, and low-stress zinc deposits, which are critical for high-performance corrosion protection and wear resistance. This makes it an essential raw material for manufacturers in the automotive, aerospace, fastener, and electronics industries seeking superior metal coating solutions.

Application

• Acid Zinc Electroplating: A primary component in sulfamate-based plating baths for rack and barrel plating, offering excellent throwing power and deposit uniformity.
• High-Speed Electroplating: Used in processes requiring rapid deposition rates while maintaining quality, such as for wire and strip plating.
• Low-Stress Zinc Deposits: Critical for plating components susceptible to hydrogen embrittlement or dimensional fatigue, including springs and high-strength steel parts.
• Alloy Plating: Serves as a zinc source in the electrodeposition of zinc-nickel, zinc-cobalt, or zinc-iron alloys for enhanced corrosion resistance.
• Printed Circuit Board (PCB) Manufacturing: Used in certain plating formulations for electronic components and connectors.
• Metal Finishing & Corrosion Protection: Provides a sacrificial coating on iron and steel substrates across automotive, aerospace, and industrial hardware.
• Research & Development: Employed in laboratories for developing new plating chemistries and surface treatment technologies.

Quality Control

Our Zinc Sulfamate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and performance in demanding electroplating applications. Each lot is tested against stringent specifications for key parameters such as zinc content, sulfamate content, and impurity levels. A comprehensive Certificate of Analysis (COA) detailing assay results and trace metal analysis is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C). The original container should be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking and reduced solubility.
