After an extensive seven-month testing period, Nalco’s DustBind Plus Technology proved it can meet this dust mitigation requirement. DustBind Plus technology is a patent-pending, VOC-free, car topper agent with a freeze point of -20°F (-29°C). This is an advantage over other toppers that typically have a freeze point of 32°F (0°C) due to their high water content. The DustBind Plus agent forms a flexible, yet durable crust on the coal or mineral surface, providing dust control even as the material settles during transit.
