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
