Dacromet Series

Updated: 2026-09-18

Overview

The Dacromet Series refers to a family of zinc-aluminum flake coatings developed for superior corrosion protection. Unlike traditional zinc plating, Dacromet coatings are applied through a water-based process, making them more environmentally friendly. These coatings are known for their ability to withstand harsh environments, including high temperatures and salt spray, making them ideal for demanding industrial applications. The technology behind Dacromet was originally developed in the 1960s and has since evolved to meet modern environmental and performance standards. Today, it is widely used across multiple industries, particularly where long-term corrosion resistance is critical. The coating process involves dipping or spraying components with the Dacromet solution, followed by curing at high temperatures to form a durable protective layer.

Physical and Chemical Properties

Dacromet coatings are characterized by their unique flake-like structure, which provides excellent barrier protection against corrosion. The coatings typically consist of zinc and aluminum flakes suspended in a water-based binder. This composition ensures high resistance to salt spray, often exceeding 1,000 hours in standardized tests. Additionally, Dacromet coatings can withstand temperatures up to 300°C without significant degradation. Chemically, Dacromet is inert to most solvents and oils, making it suitable for use in environments where chemical exposure is a concern. The coating also exhibits good adhesion to various substrates, including steel, iron, and aluminum. Its low friction coefficient makes it suitable for applications where parts may experience wear or mechanical stress.

Main Applications

The Dacromet Series is extensively used in the automotive industry for components such as brake calipers, fasteners, and exhaust systems. Its ability to resist corrosion under high temperatures and harsh conditions makes it particularly valuable in this sector. Aerospace applications include landing gear components and engine parts, where reliability and longevity are paramount. In the construction industry, Dacromet coatings are applied to structural steel, bolts, and other hardware exposed to outdoor conditions. Electrical enclosures and marine equipment also benefit from the coating's resistance to saltwater and humidity. The versatility of Dacromet makes it a preferred choice for industries requiring durable, long-lasting corrosion protection.

Safety and Storage

Dacromet coatings are generally considered safe to handle, as they are free from hexavalent chromium and other hazardous substances. However, proper ventilation is recommended during application to avoid inhalation of dust or fumes. The coatings are non-flammable and do not emit harmful vapors under normal conditions. Storage of Dacromet products should be in a cool, dry environment to prevent moisture absorption or contamination. Containers should be kept tightly sealed when not in use. Shelf life typically ranges from 6 to 12 months, depending on storage conditions. Disposal should follow local environmental regulations, as the coatings may contain trace metals.

B2B Procurement Guide

When procuring Dacromet Series coatings, it is essential to verify the supplier's compliance with relevant industry standards, such as ASTM or ISO specifications. Technical data sheets should be reviewed to confirm performance characteristics like salt spray resistance and adhesion strength. Volume discounts are commonly available for large orders, and suppliers may offer customized solutions for specific applications. Lead times can vary depending on the complexity of the order and the supplier's production capacity. It is advisable to establish long-term relationships with reputable manufacturers to ensure consistent quality and reliable delivery. Testing samples before full-scale procurement is recommended to validate performance under actual operating conditions.
