Application Rates
NASi SF can be applied with all standard airport solid spreading equipment.
The application of products is distinguished as either anti-icing or de-icing. Anti-icing is to apply immediately prior to the onset of freeze conditions to prevent the bond of precipitation with pavement. It is considered the most efficient use of chemicals. De-icing is to apply product after an event to aid in the removal of ice and snow. The following suggested rates will vary depending on a range of conditions including air temperature, humidity, precipitation type, wind, ground temperature, surface material and application equipment.
