Frequently Asked Questions
The questions customers ask most during selection — each links to the technical answer and matching products.
Cleaning coated optical glass without damaging the coating or overflowing the tank
Two hard constraints: chemistry mild on the deposited film (neutral system) and no foaming in spray operation. ZL-001 uses a neutral system (3–10% working solution) with a low-foam design, cleaning in 1–3 min at 45–50 °C without tank overflow or spray-pressure loss.
Read answer →How to remove stubborn screen-print ink from phone glass?
Aqueous alkaline boil-off often fails on stubborn screen-print ink. Match the ink system: L506 for TOYO inks (alkali + penetrant dual channel); BL-7M056-V2 for high-volume back-cover/frame stripping (80 °C, ~7 min, 1581 parts validated); L515 high-solvent custom grades for unusual inks.
Read answer →How to clean oil and coolant residue before curved-glass hot bending?
Pre-bending cleaning must remove machining oils and coolant residue; otherwise they convert into pits, haze and mold contamination in the hot zone. L18S is a medium-strong alkaline aqueous system that handles both in one step.
