Silica XG layers have a newly developed binding agent that makes it adhere to the aluminum substrate more strongly than the Silica G layers.  This equates to less flaking of the coating.

For these TLC plates a silica gel with a 60Å mean pore diameter, a 500m2/g specific surface area, a 0.75 ml/g specific pore volume, and a particle size of 5-17um is used.  Fluorescent indicator (UV254) and pre-cut sizes are available.

Silica XG: This is a soft layer plate that contains Gypsum.
