Bovi-Bond urethane adhesive, from USA, is a proven system for attaching blocks to the healthy claw of lame cows’ hooves. Bovi-Bond does not need any special skill to mix and apply. The secret is in the double-barrel 160ml adhesive cartridge and the special dispensing gun. This system ensures that the two parts of the adhesive mixture are kept separate until they merge in the mixing tip. After treating the affected claw, the healthy claw is trimmed to leave a clean, flat and dry surface. Follow the instructions below for preparation of the cartridge for loading into the dispensing gun. Apply about 20ml (a 3mm-thick layer) to the clean hoof surface. Press the block lightly onto the adhesive, and hold still for 30 seconds. The block will wear off or break off naturally, by which time, if you repaired it correctly, the affected claw should have made a recovery. Bovi-Bond adhesive sets in approximately 30 seconds after application of the block. It can be load-bearing after 2 or 3 minutes (or slightly longer in cold weather). The 8-pack set above contains the adhesive cartridge plus 8 mixing tips and 8 blocks. The dispensing gun must be purchased separately. After opening, the Bovi-Bond adhesive cartridge must be used within one year.
