Ice Melt Crystals are perfect for use on roads, car parks, airports, waiting platforms, loading bays, walkways, etc. Ice Melt Crystals are an exorthermic chemical that melt snow and ice up to 8 times faster than ordinary salt. Ice Melt Crystals are effective down to lower temperatures than salt and are less corrosive than salt. Ice Melt Crystals should be thinly sprinkled over the affected area with a trowel and will react exothermically (produce heat) when added to water or ice so rapidly melt ice or snow covered surfaces. The residual product acts as salt but more efficiently by lowering the freezing point of water and thus inhibits refreezing. Unlike salt, this highly effective lightweight product is less corrosive, leaves no residue and will not damage the surface or discolour boots, shoes, carpets, etc. Ice Melt Crystals work for longer than salt and give greater coverage.
