10ml LOCA (Liquid Optically Clear Adhesive) Glue repairs approximately 5 phones! If this is your first repair, we HIGHLY RECOMMEND using at least a 10ml tube. Using a smaller volume like 5ml may not yield enough adhesive in case you make mistakes and need to try again. DESIGNED FOR SMART PHONE SCREEN REPAIR: Xfactor UV GLUE Liquid Optical Clear Adhesive (LOCA) is formulated especially for bonding the outer glass to the digitizer in a smart phone or tablet display assembly. Compatible with all touchscreen devices such as iPhones, iPad, Kindle, Samsung, LG, Motorola, and other phones and tablets needing LOCA to attach glass and/or digitizer to LCD PROFESSIONAL GRADE, ULTRA LOW VISCOSITY adhesive dries clear! - 2000mPa*s viscosity (general LOCAs average 5000mPa*s). Thanks to such LOW VISCOSITY, bubbles/voids can be easily removed, smaller amounts of glue can be used, easier to clean, flows well, & cures with NO YELLOWING EFFECT, GUARANTEED!
