Introducing the "Discoloration Preventive Agent for Copper Plating" handled by Chiyoda Chemical Co., Ltd. During the water washing process after discoloration prevention treatment, when lifting the plated sheets and parts, if the water does not flow down smoothly, it will adhere to the plated sheets and parts, causing stains. Conventional products have water-repellent properties when new, but after prolonged use, the plating solution mixes with the discoloration preventive liquid, reducing water repellency and causing stains. Our product maintains its water-repellent properties even when mixed with the plating solution. 【Product Details】 ■ Solubility: (soluble) water, alcohol, glycol ■ Appearance: colorless to yellow liquid ■ Packaging: (can) 22kg (drum) 240kg *For more details, please refer to the PDF document or feel free to contact us.
