De-ice is a granular compound with exothermic (heat generating) action which gets to work immediately on contact, each individual granule burrowing rapidly through the surface. The speed of ice melting has to be seen to be believed ! De-ice is ideal for use around factory reception areas, hospitals, A & E areas, old peoples' homes, supermarkets and shopping malls. In fact, anywhere where slip hazards may exist. De-ice remains effective to lower temperatures than salt (- 35°C) and is used in much smaller quantity providing a cleaner, safer environment. De-ice is also residual and provides refreeze protection overnight.
