Quantsil L with low and Quantsil H with high luminescent index are supplied as a two-part liquid component kit for the preparation of a hydrophobic, flexible, precise molding and encapsulation silicone material. The difference between these products is a concentration of quantum dots based luminescent pigment (Zno-QDs).
The mixture (10 to 1 mix ratio) can be cured at room temperature (2 days) or at elevated temperatures (for several dozen of minutes). The resulting cured polydimethylsiloxane (PDMS) is chemically inert, has good gas permeability, thermal stability and it is optically transparent. Multiple packaging sizes are available for this product.

- Luminescent PDMS Preparation
- Mix component A with component B using 10:1 (w/w) ratio (for ca. 10 minutes)
- Mixing generates a lot of air bubbles. Thus, leave the as-prepared mixture for about 1 hour at room temperature or use a vacuum desiccator for 20 min to remove bubbles.
- Place the material in the mold (ie. glass or silicone) and again remove bubbles if necessary.
- Cure the material at room temperature (ca. 25°C) for 48 hours or in the furnace at 90°C for 1 hour.
- Remove the materials from the mold carefully. The resulting PDMS should be stable for at least six months.
