Chongqing Bo Sheng Surface Technology Development Co., Ltd. was jointly established by a surface technology expert from the United States and local entrepreneurs. We specialize in the research, development, production, and sales of new surface treatment and analytical instruments. Our newly launched generation of lavender purple iron blackening solution at room temperature utilizes self-developed patented technology, significantly reducing blackening sludge, minimizing effective component loss, and substantially enhancing the blackening efficiency and quality. The blackening area per kilogram of the solution can reach as high as 18-22 square meters (while traditional room temperature blackening products only achieve 3-9 square meters). After extensive testing, we have突破 the technical challenges of room temperature blackening, making it a high-quality, low-cost practical process. Additionally, we also research, develop, and sell copper electroless nickel plating, copper alloy room temperature blackening, room temperature color film phosphatizing, degreasing, rust prevention, cutting fluids, and more.
