ST-201 is a high functional chemical polishing agent to enhance the surface roughness and glossiness of carbon steel and its alloy. The application method of ST-201 is as below.
• Improves surface roughness and provides high glossiness
• Improves adhesion of plating
• Concentration of solution is controllable depends on steel grade
• Solution can be used for long time
• ST-201 can be handled in room temperature (10~25℃)
• Short time of application
