MB series

MB series are photosensitive films with alkaline developer for RIB patterning on several base materials, which can produce excellent fine structures.

Features

Due to the film shape, it makes uniform thickness and good workability.
Due to the high performance of photo sensitively and developing ability, it can produce fine patterning on the large-area in a lump.
Good adhesiveness with glass or various resin base materials
Colorless or several colored types are available upon requests.

Example of Application

- Example for Display Materials: preparing rib structure
