Equi-Pak CS is a copper sulfate infused liquid urethane that sets in 60 seconds and is used as a pour-in pad to provide comfort, protection and therapeutic support for equine feet. It bonds directly to the sole and frog and can be used by itself as an instant pad, or as a packing underneath a pad. Equi-Pak CS limits exfoliation, promotes sole depth and makes the bottom of the hoof impervious to injury from sharp objects.
