Gfro-1
Glass Frost Etchant (Haze 90% ↑)
Gfro-1 is a high functional glass frost etchant which can substitute HF. It minimizes corrosion on glasses and has low toxicity to human body, equipment and environment. Gfro-1 can be applied by simple dipping as the solution is in sludge (liquid) state, this simplifies unnecessary and dangerous procedures.
[Features]
• Nearly no corrosion and irritation on the equipment and human body
• Surface of glass shall be etched with light milky color after the processing
• The solution is in liquid state, mixing process and related equipment are not necessary
• Does not create HF gas and provides stable processing condition. Leads to excellent usability
• Improves productivity by etching glasses stably
• Surface can be rinsed off easily after etching
