What is UV Glue Tempered Glass?

UV tempered glass package comes with something called LOCA gel. LOCA is a short form of ‘Liquid Optically Clear Adhesive). LOCA gel is used to stick cover lens, glass etc to phone’s body and as it is a clear adhesive, it has superior optical properties. As you use Ultraviolet light (UV) to heal the liquid UV glue, these accessory makers started calling this ‘UV glass’.

Liquid optically clear adhesive (LOCA) is liquid-based bonding technology used in touch panels and display devices to bind the cover lens, plastic, or other optical materials to the main sensor unit or each other. These adhesives improve optical characteristics and durability. LOCA glue is often hardened using ultraviolet light.

How to choose a good UV glue tempered glass?

UV glue tempered glass first appeared in 2018, but until now, most products on the market have the following problems

The accessories are scattered and the installation is cumbersome. Once an error occurs, a glass can only be scrapped (picture);

The curing time is very long (2 minutes);

Once cured, it is difficult to tear up. For example, if your tempered glass is accidentally broken and needs to be replaced with a new tempered glass, you may hurt your hands (picture);

Glue overflowed during installation, sticking to the side buttons, resulting in scrap (picture)
