It is a non-bonding, skin-safe silicone packing material dispensed under a pad to seal, protect and cushion the equine foot. It totally fills and seals all void areas and prevents debris migration. Sil-Pak Soft applications are weight bearing in 2 minutes. Auto-mix cartridge system ensures consistent performance and predictable set time. These are the same cartridges as the rest of the Vettec line and require the same 210 tips.
