COLD BLACKENING CHEMICAL - VCBLK HB-18
Cold blackening is a process used to impart a durable black finish to metal surfaces, primarily steel and iron, through a chemical reaction. The VCBLK HB-18 is a specific cold blackening chemical formulation designed for this purpose. Here’s an overview of what VCBLK HB-18 is, its uses, and some considerations:
* Process
1. Preparation: The metal surface must be cleaned and degreased thoroughly to ensure proper adhesion of the blackening layer.
2. Application: The VCBLK HB-18 solution is applied to the metal surface, typically through immersion, brushing, or spraying.
3. Reaction Time: The metal is left in the solution for a specified time to achieve the desired thickness of the black oxide layer.
4. Rinsing and Sealing: After blackening, the metal is rinsed to remove any excess chemical and often sealed with oil or another protective coating to enhance durability and corrosion resistance.
