What is the technology to extend the service life of coating films by inorganic-organic hybridization?
Recently, there has been growing need to extend the maintenance cycle of high-rise condominiums and steel structures. This requires highly durable paints that contribute to reducing the life cycle cost of buildings. We have achieved durability beyond that of fluororesin paints by taking full advantage of hybridization technology of inorganic and organic components.
What are the key features of this technology?
Inorganic components, like stone and glass, are characterized by superb chemical stability. The binding energy is stronger than the ultraviolet energy of sunlight and is the source of durability. Inorganic components demonstrate excellent durability, but they lack flexibility and are vulnerable to bending. Hybridization with special flexible organic components helps harness the advantages of both types of components to demonstrate superb durability.
* Ultraviolet energy: 410 kJ/mol
* Binding energy of Si-O in inorganic polymers: 444 kJ/mol
Contribution to solving social issues
The number of high-rise buildings, which are difficult to maintain, has been increasing, and there has been growing need to extend the maintenance cycle. Inorganic paints contribute to reducing the life cycle cost of buildings due to their superb weather resistance.
