The processing technology is extremely simple and does not require special equipment; a small amount can be handled with a plastic bucket.
The black dyeing process for nickel metal can be easily done at room temperature by anyone, anywhere. (This product is a concentrated solution, so it should be diluted with tap water before use.) 【Target Metals】 It can be widely used for black dyeing of finished products and parts made of nickel metal. - Pressed parts, pins, screws, bolts, nuts, washers, springs, shafts. - Finished products or cast parts of machines, tools, and molds. - Black dyeing or repair of parts of assembled machines. 【Characteristics】 - It allows for black dyeing at room temperature through immersion. No special equipment is required. - The processing technique is extremely simple and does not require special equipment; a plastic bucket is sufficient for small quantities. - Even complex shapes of the items being treated can achieve a uniform coating. - Since the processing temperature is at room temperature, it does not damage the material. - The black dye is odorless, non-flammable, and does not deteriorate over long-term storage. - There is almost no change in dimensions before and after processing. - It is an acid aqueous solution that blackens nickel metal and colors it purple at room temperature. - It is safe and economical to use, dissolving in water without danger during work and can be diluted for use.

basic information
1. **Degreasing**: Black dye processing requires complete degreasing due to chemical reactions. (Note: Insufficient degreasing can cause dye unevenness.) For degreasing agents, there is Trichlorethylene or a dedicated degreasing agent, Tobikamarit, a water-based degreasing cleaner made by Tobi Co. In the case of Trichlorethylene degreasing, immerse the item to be dyed for 1-2 minutes, ensure it is fully degreased, then remove and let it dry naturally. 2. **Surface Activation**: If there is rust or smut, immerse in a 10% hydrochloric acid solution (a solution diluted 2-3 times with water from industrial hydrochloric acid) for 1-2 minutes. 3. **Black Dye Treatment**: Dilute the room temperature black dye Tobik Blacky N with water (distilled water or tap water) at a ratio of 1:2-3. Place the pre-treated item into this solution and stir up and down several times while immersing for 30 seconds to 1 minute. (Be careful, as using the undiluted solution or insufficient dilution can lead to poor fixation.) 4. **Washing (Hot Washing)**: Since black "sludge" adheres to the surface, please wash it off with a sponge or cloth. 5. **Black Dye Finishing**: For nickel parts that have been black dyed and washed, immerse or apply the black dye finishing agent Metal Clean or (Special) concentrated solution for 5-10 minutes to finish.
