Facts of Dome Epoxy Resin

Two options: hard or soft epoxy

• Soft Epoxy: is a clear, thermosetting resin to encase a (graphical) surface. Epoxy Potting process is taken place in a cleanroom of Class 100,000.
• Hard Epoxy: is a clear, resin to encase a (graphical) surface and needs to be cured under UV chamber. Epoxy Potting process is taken place in a cleanroom of Class 100,000.

Dome-shaped Epoxy Potting is intended for perfectly horizontally flat surface. It is not intended for concave or indented surface – due to its capillary nature.

Stemming from its property of capillary action, corner of the treated surface (top-view) must have a radius angle instead of a acute angle.

Advantages

• Optical clear.
• High performance bonding and sealing.
• Harden and can protect treated surface.
• Excellent resistance to thermal shock.
• Superior chemcial resistance.
• Abrasion resistance.

Limitations

Generally speaking:

• For Regular Shape:
  • Diameter or Width or Length: 2mm to 25mm
  • Height: about 1mm
• For Relatively Irregular Shape:
  • Diameter or Width or Length: 2mm to 20mm
  • Height: about 1mm
