By using aluminum as the base material, the surface becomes smooth and it is possible to observe at low to medium magnification without worrying about the background. Also, drift is reduced and fine particles can be observed at higher magnification. Quality has been improved compared to conventional non-woven fabric base materials, such as easier removal.
The surface is black because it is an adhesive containing carbon powder as a conductive filler.
However, it uses an acrylic adhesive and may melt when heated. This product is intended for use at room temperature.
