As a key ingredient, we use siliconized resin (pure silicon and denatured silicon) that excels in heat resistance and weather resistance. We use metal oxide and reinforcing materials suchas pigments and combined it so it best suits the heat resisting conditions and general terms.

Siliconized resin is the combination of organic groups such as methyl and phenyl and it also has the Si-O-Si bone structure very similar to glass. The strong point of siliconized resin is that it changes from organic film (the general organic resin) to hard inorganic film (similar to ceramics) at around 300°C.

The heat resistant temperature that is indicated on the heat resistant paint is determined by the overall performance of adhesion, anti-corrosion, and discoloration.

In general, we target ordinary steel boards to use as the painting material. Recently, our paints have often been used on coated steel plates, aluminum, and stainless steel. However, the materials themselves have thermal limits.

Ordinary Steel Boards	Up to 600°C
Hot Dip Galvanized Steel Boards	Up to 400°C
Electrogalvanized Steel Boards	Up to 200°C
Aluminized Steel Boards	Up to 400～500°C
Aluminum	Up to 500°C
Stainless steel	Up to 800°C
Transformation film	Up to 300°C

 

 

Physical Surface Treatment
Blast Processing	A rust removing method that uses the blast machine to blow river sand onto the surface at a high pressure.
Methods using power tools	A method used to scrape off the rust from the surface by using a sander or a grinder.
Methods using hand tools	A method used to scrape off the rust by hand by using a wire brush or sandpaper.

Chemical Surface Treatment
Removing oil	A method used to remove oil by solvent cleaning and a degreasing agent.
Removing rust	A method used to remove rust by using strong acid. This is also called pickling.
Surface adjustment	Adjusting the surface so that the transformation film forms equally on the surface.
Conversion Treatment	Form a phosphoric acid zinc film to have better anti-corrosion and adhesion.

Okitsumo's products do not have the distinctiveness of heat resistant paints, so it can be treated in the same way like you will in a general painting operation. It is also possible to do electrostatic coating as long as you are careful about the thinner's electrostatic property and dryness. Also, there are some general components that include large amounts of metal pigments, so please mix thoroughly before application.

The film thickness is a very important component when it comes to maintaining the heat resistance, beauty and anti-corrosion for a long period of time. The standard film thickness is very important because it brings out the highest performance of paint. The initial heating should be done gradually. When the thickness exceeds the standard film thickness and you have heated it rapidly, the residual solvent and the reactive gas that have occurred during the hardening of the paint film will increase and the peeling caused by the swelling of the paint film could be the cause of performance degradation.

Please choose the appropriate paint according to the object's temperature conditions and the functions that it requires. If you present the requirements to our company, we will choose the appropriate paint for you, so please feel free to contact us. We will choose the appropriate paint according to the information that you give us, such as purpose, color, gloss, paint type, dryness condition, heat resistant temperature, material, surface treatment, painting method, capacity, and the required performance.

・Please store paint indoors in a well-ventilated place while obeying the law.

・Please do not use where there is a possibility of fire.

・While painting and drying, make sure that the place is well ventilated and do not inhale any type of steam or gas.

・When you have stored the paint for a long period of time, hard sediments may appear in the paint even though the lid is completely sealed.

・Please mix thoroughly before use. If the paint container expands by any chance, please contact us.
