SB-219SE
SUS Etchant (Micro-etching)
Sand Blast-219SE is a micro-etchant which is used for sand blast process of SUS surface with wet corrosion method. SB-219SE is developed considering effects on human body and environment, provides high quality surface by micro-etching, and does not corrode material and facilities.
[Features]
• Provides easier working condition compared to dry corrosion method
• Provides clean surface by removing oxide scale etc. at the same time of etching
• Nearly no acid gas generated, and no excessive corrosion of material and facilities
• Easy to do post process such as filming, etc.
