Tyranno Coat®

Tyranno Coat®

Fine ceramic is a material now getting a lot of attention from different areas, thanks to outstanding properties that include hardness, as well as high temperature, oxidation, and chemical resistance. When a thin film of this ceramic is applied to various materials, it can be used to make products with excellent heat and corrosion resistance features. UBE has produced a new paint based on this technology, using its proprietary Tyranno Polymer. The polymer is a type of organic silicon compound that dissolves easily in various organic solvents to make a paint or spray. When heated, the coating takes on heat-cured properties. Tyranno Coat® was developed with this polymer as the main ingredient, and has a variety of applications.

  • Testing was JIS K5400 compliant.
  • A 40-micron coating was applied to a SUS304 steel plate, 1-mm thick (previously polished with No. 240 sandpaper, 100 mm 100 mm, and degreased with acetone), and the sample was baked for 10 minutes at 250°C.

Coating and Baking

1) Preparation of the application surface

Degrease the surface with a solvent such as acetone or trichlorethylene, and then sandblast it.

2) Paint agitation

As the fillers in Tyranno Coat settle relatively easily, it must be properly shaken or stirred to a uniform consistency.

3) Coating

Apply with a regular paint applicator by brushing, spraying, or dipping. Use xylene if Tyranno Coat needs to be diluted, according to the following proportions, as a general rule.

Brushing 0%-5% (by weight)
Spraying 0%-10%

Brushing A lacquer brush or a cylindrical brush works well.
Spraying Nozzle diameter should be about 0.6 mm to 1.2 mm, and pressure of 3 kg/cm2 is preferable.
Dipping Use a container with an agitator and a hydrometer.

It is best to apply 2 or 3 coats for both undercoat and topcoat. The preferable final thickness is in the range of 40±10 microns.

4) Heat curing

After painting, air-dry for 5 minutes. Then bake for at least 10 minutes at 250°C or higher.

5) Notes

  • Painting should be performed at temperatures below 60°C, in principle.
  • Do not paint during high humidity, or outdoors in the rain.
  • Ensure proper ventilation while handling or applying the paint to avoid inhalation.
    Protective clothing is recommended to avoid skin contact. Keep product away from flames.
  • Rapid heating may cause blistering or pinholes in the applied coating.
