Skid preventing and snow-melting properties of a two-layer structure snow melting agent

Snow-melting agents are sprinkled to prevent automobile slip. However, chlorine ions cause damage such as corrosion. The author has developed a new type of snow-melting agent that needs a great deal less an amount of calcium chloride and has a larger snow-melting effect than calcium chloride. The agent is a snow-melting agent with a two-layer structure in which a heat storage material is coated with a snow-melting agent. Our two-layer snow-melting agent has a snow melting effect 1.3 times and sliding friction effect 1.5 times greater than the snow melting agents on the market by using a 20% coating. The agent reduces the damage caused by the chloride ions to one-fifth and so it is a snow-melting agent with a small environmental load.
