basic information
**Features** - Contains three types of metals: zinc, tin, and aluminum, and despite having a film thickness of 5 microns, it exhibits high corrosion resistance with no rust occurring even after 2000 hours in a unique salt spray test, achieving an excellent adhesive film. The coating is flat and smooth, allowing for smooth fitting of bolts and nuts, and reducing damage to the film during screwing. - Generally, during surface treatment processes such as pickling or electroplating, hydrogen is absorbed into the steel, leading to hydrogen embrittlement. This treatment does not cause hydrogen embrittlement, making it suitable for high-strength bolts and high-carbon steel materials. - No harmful substances listed in the RoHS Directive 6, including hexavalent chromium, lead, cadmium, and mercury, are used, and it complies with REACH regulations, ensuring an environmentally friendly treatment. **Specifications** **Process**: Pre-treatment → 1st coat → Baking treatment → 2nd coat → Baking treatment **Treatment Method** - Dipping treatment *Note: For spray treatment, the maximum processable dimensions are up to 600 mm square.
