AI Technical Summary

Benefits of technology

The technical effect of this patented technology is that it provides specific types of fine ceramics called submicrocerams (sub microns) which can be used for coatings without losing their properties or causing corrosive damage during use. This results in longer lifespan compared to previous methods while maintaining good performance against various environmental factors such as rain water, salt sprays, humidity, temperature changes, etc..

Problems solved by technology

The technical problem addressed in this patented text relates to improving the durability and appearance quality of metallic surfaces treated with fluoro carbon layers due to their lower rigidity or lack of wear resistant properties compared to traditional organosilane coatings used for protection against rustiness.
