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.

    These coatings contain a high percentage of zinc particles that provide cathodic protection to the underlying metal substrate. Zinc-rich coatings are used in a variety of applications, including bridges, pipelines, and marine structures.

  • Epoxy coatings:

    Epoxy coatings provide excellent adhesion and chemical resistance, making them ideal for use in harsh environments. They are commonly used in the aerospace, automotive, and industrial sectors.

  • Ceramic coatings:

    Ceramic coatings offer excellent resistance to heat, wear, and corrosion, making them ideal for use in high-temperature applications. They are commonly used in the energy, aerospace, and automotive industries.

  • Inorganic coatings:

    Inorganic coatings, such as phosphates and chromates, provide excellent resistance to corrosion and can be applied to a wide range of metals and alloys. They are commonly used in the automotive, aerospace, and electronics industries.

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.
