GT-250MG4
Pattern Etchant
GT-250MG4 is developed to substitute HF which is used for cleaning and etching glasses and it can be applied in organic EL etching process. GT-250MG4 significantly lowers corrosion and irritation to and of the targeted glass, human body, equipment, and environment compared to HF. GT-250MG4 also improves the surface quality of panel glasses.
[Features]
• Its corrosiveness and irritation to human body and equipment are significantly lower than HF
• The cleaning power on pollutants of panel glasses’ surface is very strong and helps maintaining the clean surface
• Significantly increases the cleaning efficiency as no excessive corrosion and erosion occur
• Provides stable surface condition for coating process after cleaning
• No HF gas generated and provides stable cleaning effects
• Provides the good surface roughness
