Features: Ideal for replacing defective or broken touch screen LCD screens. This is a true LOCA (Liquid Optical Clear Glue) gel. The syringe will protect it from the hardening of conventional lights. UV light curing UV glue must be cured using UV light. It will harden in about 30 seconds, but it is recommended to cure for about 3 minutes. Sunlight can also be used, but it takes more time to cure. Original UV glue LOCA liquid optical transparent adhesive for mobile phone cover glass LCD screen repair. Installed in an syringe, which protects glue from normal light and hardens it.

Clean the LCD screen area. 2. Apply about 1.5g of UV glue to the middle of the LCD screen. 3. Make sure the area of the LCD screen is clean, except for the area where you use UV glue and prepare the front glass for glue. 4. Glue the front glass correctly. 5. After the UV glue is applied, the entire screen is exposed to ultraviolet light, and the UV glue cures for 3-5 minutes. Note: 1. If you are not a technician, please do not buy. 2. Do not use fluorescent lamps when soldering. Fluorescence emits ultraviolet light, which is sufficient to slowly cure the glue. For longer working hours, work under normal light bulb or LED lighting. You can even put the lights far away if needed. Also, if you don't have UV light, don't forget that sunny days can also cure this glue. Just 3 minutes. Cloudy cloudy days may take longer. 3.
