Dacromet

Dacromet is an advanced, chromium-based inorganic coating applied through a dipping and baking process. It forms a thin, silver-gray layer that provides exceptional corrosion resistance, heat tolerance up to 300C, and excellent adhesion without hydrogen embrittlement risk.

Product details

Typical Applications:

Automotive & Chassis Components: Widely used for high-strength screws in brake systems, engines, and underbody parts exposed to road salts and severe conditions.
Outdoor Infrastructure & Fasteners: Ideal for screws used in power transmission towers, highway guardrails, and agricultural equipment requiring long-term weathering resistance.
General High-Corrosion Environments: A preferred alternative to standard galvanizing for screws in chemical, marine, and industrial atmospheres.

Our Coating & Custom Capabilities:
We apply Dacromet coating to screws to meet stringent anti-corrosion specifications. Our service focuses on:

Process Control: Ensuring consistent coating thickness and full coverage, even on complex threads, to provide reliable salt spray resistance (often exceeding 500 hours to white rust).
Material Compatibility: Coating high-strength screws (e.g., Grade 8.8, 10.9, 12.9) without compromising their mechanical properties.
Custom Specifications: Adjusting coating thickness, and offering options for different sealing treatments to enhance performance against specific chemicals or humidity.

Our Dacromet coating provides screws with superior, environmentally friendly protection for the most demanding applications, ensuring durability and reduced lifecycle maintenance.
