This is our medium Urethane, Shore-50 in our line-up. It can be used in a variety of applications, for instance as a filling of the hoof. The biggest advantage of this ISI-PACK MEDIUM is it’s stickiness to the sole together with the ISI-PACK pad/net, making sure that the filling stays in its place. The set time is 2 minutes, which can vary due to different conditions (weather conditions & humidity).
