What is heat resistant paint?
Heat resistant paint is applied to high-temperature equipment or objects in order to prevent thermal oxidation and corrosion and to maintain good appearance. The paint film must not undergo heat decomposition nor deterioration at high temperatures but must maintain adhesiveness to the substrate. It is used for many things such as engines and mufflers of automobiles and motorcycles, chimneys, microwave ovens, cooking utensils, frying pans, and heaters etc. In recent years, new heat resistant paints have been commercialized with additional functions such as heat insulation and heat releasing properties.
Why does heat resistant paint withstand heat?
The combination with resin, pigment, and reinforcing material allows heat-resistant paint film to form. Heat resistant paint is produced by our company's base technology, or organic-inorganic composite technology, which extracts ideal or necessary features from both organic and inorganic materials. (

What is heat resistant paint made from?
Heat resistant paint uses silicon resin (pure silicon, modified silicon) as the main component and uses metal oxide and reinforcing material as pigment.
In recent years, products using engineering plastic fluorine and PEEK resins and nanosized inorganic fillers have been also developed(

How is heat resistance determined?
After heat tests (heat resistance test) based on assumed actual use, adhesion and corrosion resistance etc. are evaluated, and then the heat resistance is determined by overall performances of adhesion, corrosion resistance, and discoloration and so on. Also, the heat resistance of the material itself must be considered.

What is functional paint?
Essentially, paints have two functions; to protect the substrate and to decorate the materials. In recent years, new paints with additional functions have been developed and such paints are called functional paints. Heat resistance is also regarded as one of such new functions.
What are types of functional paints?
The functional paints include environment-responsive paint, heat functional paint, and light functional paint. Heat resistant paint is a leading product of the heat functional paint. Our company is developing new functional paints in which environmental responsiveness and light function are incorporated in addition to the basic heat functional paints.(

Is it possible to change the color of heat resistant paint?
Colors of some paints such as Color Flon 10G series, Color Flon 10F series, 300 series and Bose Neos Color can be adjusted.
Please consult us about possible color range.
Is heat resistant paint different from fire prevention paint?
They are different from each other. The heat resistant paint adheres to the base material without decomposing or deteriorating at high temperatures to protect the base material from thermal oxidation and corrosion and to maintain the aesthetic appearance. On the other hand, fire prevention paint suppresses burning, the spread of fire to wood material, and heat deterioration of metal material.
What is a process of surface treatment before painting?
When painting, treat the surface in accordance with the paint specification in reference to the table below.

Process |
Treatment |
Removal of rust |
Physical process |
Mechanical treatment via blast processing. Hand working with an electric sander or a wire brush. |
Chemical process |
Acid cleaning treatment: Remove rust on the surface by immersing the painting material into a solution of hydrochloric acid and sulfuric acid. |
Degreasing |
Solvent process |
Wash with naphtha, gasoline, benzine, or trichloroethane, or perform vapor washing. |
Alkaline process |
Immerse the painting material into an alkali solution of sodium hydroxide and sodium carbonate, or spray such solution on it. |
Planarization of paintwork |
Polishing process |
Polish the surface with a grinder, file, or sandpaper. |
Filling process |
Fill a pate or solder. |
Giving corrosion resistance and adhesion |
Chemical process |
Chemical reactions between metal surfaces and the composition in the treatment liquid form the chemical film on the surface. Form a phosphoric acid zinc film to increase corrosion resistance and adhesion. |
