AI Technical Summary

Benefits of technology

This new type of coating material can be used effectively for protection against rusting or damage caused from rainwater while also providing improved durability over time due to its ability to bond well with metals without causing any issues like cracked plates that could harm them during use. Additionally, this coatings provide superior water repelling characteristics compared to existing paints made up mostly of organic solvents which may cause environmental concerns such as volatile emissions (VOC). Overall, these technical improvements make it possible to create stronger yet more effective materials for various applications where they're needed.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the durability or long life span of existing antirust coatings that were developed over time due to factors like weather conditions (temperature) changes caused by temperature fluctuations during winter months when they may affect other parts on the same platform). Additionally, there was also concerns about reducing damage from rusts while maintaining good appearance quality through improved surface hardness without compromised glossiness. Therefore, modifying these coatings could lead to better overall efficiency and cost savings compared to traditional methods.
