AI Technical Summary

Benefits of technology

This patented technology enhances the properties of certain types of coatings made by adding specific chemical substance into an aqueous solution that makes it harder than ordinary paints without affecting their effectiveness for use on steel surfaces such as automobile body parts. These coatings have both smooth surface appearance and increased durability over longer periods compared to regular painted layers due to its unique structure formed through drying and baking processes. Additionally, this method allows for easy addition of different materials while maintaining good adherence between them during application. Overall, these technical improvements make the resulting paint more resistant against rust damage even after multiple uses.

Problems solved by technology

Technological Problem addressed in this patented technical solution describes various ways to enhance the packaging capacity of thin films containing metals like zinc and chromium without losing their effectiveness over long periods when stored at room temperature. Existing methods involve increasing the amount of filler mixed into the film, making them thicker than desired. Additionally, there may also exist issues related to improving the storage stabilization of aquatic paints that contain FeCo type materials.
