Abstract
The present invention provides a water-based coating system that can be used to form a durable, abrasion resistant, tough, protective coating on a wide range of substrates, including the underbody of transport vehicles, storage units, and the like. The coating composition includes an asphaltic component and advantageously has excellent adhesion properties when coated onto metal surfaces, including the underbody of transport vehicles, storage units and the like. The coating system is particularly effective for protecting metal or metal-containing substrates forming the underbody of an intermodal cargo container. The resultant coatings are flexible and impact resistant.
