JaaU - 5ml UV Glue LOCA(1600) for IPhone 4,5, Galaxy S2, S3, S4 LCD screen glass 5 ml JaaU UV Glue - Super Low Viscosity - 1600 (MPA.S) Liquid Optically Clear Adhesive(LOCA) stored in an amber UV light resistant syringe Super low viscosity means that Glue is not very thick and flows very easily. Not only are air bubbles less likely to occur with Glue, but they are also easier to remove. JaaU Glue's super low viscosity also means that you can get the job done with less glue than with generic LOCA formulas. Ask about other generic LOCA's viscosity values, they will be most likely over 2,000 to 5,000.
