High Corrosion Resistance Coatings
High Corrosion Resistance Coatings
Okuno offers a range of high corrosion resistance coatings that provide long-lasting protection to metals and other materials that are exposed to harsh environments. These coatings are designed to prevent corrosion from occurring by providing a barrier between the material and the corrosive elements.
Now, car manufacturers strive to create the new technology in order to help reduce carbon dioxide emissions. Not only for the reduction of carbon dioxide, but also for making more fuel-efficient vehicles, many car manufacturers have actively adopted aluminum and magnesium into automotive parts.

OKUNO's strength in silica-based coating solution
Silica-based thin coating is a method to obtain ceramic coating films by hydrolysis and condensation polymerization reaction from metallic solutions.
The thin coat can be formed by low-temperature heat treatment from 100 to 150℃ utilizing the chemical reaction (sol-gel process) in liquid phase.
In the process, covalent bond will occur on the surface of substrates between silanol group (Si-OH) and hydroxyl group (-OH), which can improve adhesion strength.
