●Corrosion-Resistant Bronze Powder (Type R)
The heat resistance of this powder is the same as standard bronze powder, but the corrosion resistance is somewhat superior to standard bronze powder. Due to its effectiveness in resisting discoloration after printing or painting and as an anti-gelling material in vehicles, it is often used on fusuma (paper doors), wallpaper, and textiles.
●Heat and Corrosion-Resistant Bronze Powder (Type HRS)
This bronze powder offers superior corrosion resistance, heat resistance, weather resistance, chemical resistance, and solvent resistance compared to standard bronze powder. Due to its extremely high performance in terms of discoloration resistance, it is often used for wallpaper, wall materials, printed textiles, leather cloth, baked-on coatings, and as a coloring agent for synthetic polymers.

Note: A variety of particle sizes are available. For questions regarding particle size, please consult FUKUDA.
