SU-8 3000

SU-8 3000 has been formulated for improved adhesion and reduced coating stress. It is being used where high bond strength and improved flexibility for microstructure fabrication is desired. As a result, adhesion to the substrate is greatly improved.

Material attributes:

  • Improved adhesion
  • Reduced coating stress
  • Vertical sidewalls
  • Greater than 100 μm film thickness in a single coat
  • Excellent dry etch resistance

Material uses:

  • Waveguides
  • Microfluidics
  • Stamps
