It involves applying a water-based coating containing zinc and aluminum flakes to the fastener, which is then cured at a high temperature. This process creates a highly corrosion-resistant, inorganic finish with exceptional performance characteristics. | | Exceptional Corrosion Resistance | This is the primary advantage. Dacromet coatings offer superior resistance to salt spray corrosion (often 500 to 1000 hours to white rust, and 1000+ hours to red rust) significantly outperforming standard zinc plating. It provides excellent protection against atmospheric, chemical, and industrial corrosion. | | No Hydrogen Embrittlement | The process is electrolysis-free, meaning there is no risk of hydrogen being introduced into the high-strength steel during coating. This eliminates the danger of hydrogen embrittlement, a critical failure mode for high-tensile fasteners (e.g., Grade 8, Class 10.9, 12.9) that are common in automotive and aerospace applications. Post-coating baking is not required for hydrogen relief. | | Excellent Heat Resistance | The silicone-based matrix of the coating can withstand continuous exposure to temperatures up to 300°C (572°F), making it suitable for applications near engines, exhaust systems, and brake assemblies. | | Uniform Coverage | The dip-spin application process allows the coating to flow evenly onto all surfaces, including recesses and threads, providing complete coverage and consistent protection without building up on threads, which helps maintain fit and tolerances. | | Galvanic Compatibility | It provides good cathodic protection to the steel substrate, similar to galvanizing. The silvery-gray finish is also aesthetically uniform. | | Not for Decorative Use | The finish is a dull, matte gray and cannot be made bright and shiny like chrome or zinc. | | Limited Abrasion Resistance | While the corrosion resistance is excellent, the coating itself can be less abrasion-resistant than mechanical platings during installation or in high-wear environments. It is often used with an appropriate lubricant/sealer. | | Cost | Generally more expensive than standard zinc or electroplating processes. | | Packaging | boxes, cartons or plastic bags, or according to customer needs. | | Category | [Assortment Kits & Mixed Fastener Sets](https://engineeringhardware.com/fastener-products/fastener-sets-assemblies/assortment-kits-mixed-fastener-sets/) | ## Technical parameters | Performance and Characteristics: | Dacromet is not a plating process but a unique surface treatment technology.
