Dacromet is a new type of surface treatment technology. Compared with traditional electroplating processes, Dacromet is considered a "green plating" technology. Its advantages are as follows:
1). Superior Corrosion Resistance: The thickness of the Dacromet film layer is only 4-8μm, but its anti-rust effect is more than 7-10 times that of traditional electro-galvanizing, hot-dip galvanizing, or paint coating methods. Standard parts and pipe fittings treated with the Dacromet process show no red rust after over 1200 hours of salt spray testing.
2). No Hydrogen Embrittlement: The Dacromet treatment process inherently eliminates the occurrence of hydrogen embrittlement, making it highly suitable for coating stress-bearing parts.
3). High Heat Resistance: Dacromet can resist high-temperature corrosion, withstanding temperatures up to 300°C and above. In contrast, traditional galvanizing processes begin to peel and fail once the temperature reaches 100°C.
4). Good Adhesion and Recoating Properties: The Dacromet coating has excellent adhesion to the metal substrate and strong bonding with other additional coatings. Parts treated with this process are easy to spray and color, and their adhesion with organic coatings even surpasses that of phosphate films.
5). Good Penetration: Due to electrostatic shielding effects, areas such as deep holes, narrow slits in workpieces, or the inner walls of pipe fittings are difficult to electroplate with zinc and cannot be protected by electroplating methods. Dacromet, however, can penetrate these areas to form a protective coating.
6). Pollution-Free and Environmentally Friendly: Throughout the entire production, processing, and workpiece coating process, Dacromet does not generate wastewater or waste gas that pollutes the environment. It requires no waste treatment, thereby reducing processing costs.
