| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| ethoxylated propargyl alcohol | 1. ethoxylated propargyl alcohol (PME for short) is a condensate of propylene * alcohol and ethylene oxide, and is also one of the most important components in nickel plating brightener; 2. The function is leveling and rapid light emission. It usually needs to be used in conjunction with BEO, PPS, PVSS, COSS, PESS or MOSS and auxiliary brightener. 3. brightener and leveling agent for nickel plating; Fast light emission, less decomposition products. 4. it is produced by high-pressure method, high-vacuum refined processing, and has the characteristics of pure product. 5. Brightener and leveling agent for nickel electroplating. Fast light, less decomposition products. Using high-pressure production, high vacuum fine processing, with product purity and other characteristics. |
| use | nickel plating leveling agent, brightener used as brightener for nickel plating and ferrous metal corrosion inhibitor brightener for nickel plating, leveling agent; fast light emission, less decomposition products. |
