Washable Coatings for Laser, Dicing and Handling Processes

DAETEC offers Water-Soluble Hard Coatings for Laser and Handling Processes in Display and Semiconductor Manufacturing Processes. Each product is carefully formulated to provide fast curing, good thermal resistance, high adhesion and can be removed easily using simple DIW or detergent rinse.

Benefit:

  • Hard, Rigid Coating
  • Tunable Viscosity
  • Inert Ingredients
  • Quick Cure (UV or Spin-Dry)
  • Fast Cleans in DIW or DaeClean Detergents

Industries:

  • Packaging
  • Handling
  • Dicing (Laser or Saw Processes)
  • Planarization Layer

During laser processing, surface protection requires the application of a simple washable coating and rinsing after laser processing, removing debris from the heat activation zone (HAZ). Our products are based upon polymer chemistries not susceptible to thermal crosslinking. We discouraged the use of polyvinyl alcohol (PVA) or polyvinyl pyrrolidone (PVP) due to their formation of thermally induced insoluble residues.
