We named this product DENTALL by combining the Japanese words for electricity ("den") and conductivity ("tall") because of its electrical conductivity characteristics.
We use a ceramic synthesis technique to produce potassium titanate fibers and a surface conductivity technique to coat the ceramic surface with a uniform conductive layer.
DENTALL is a white conductive filler that is uniformly coated with nano-order transparent
electrically conductive layers on the surface of inductors made of white potassium titanate
fibers (TISMO).
By adding DENTALL to various paints, adhesives, resins, or other materials, our customers
can provide conductivity without compromising the whiteness of these materials.
