Hysol GR17 | White Epoxy Mold Compound
- Reflective compound
- For Optocouplers
- High moldability
Hysol GR17 is a white, reflective epoxy molding compound used for optical applications. This silica filled (68%) product has been designed to improve light reflectance and workability for optocouplers also knows as photo-couplers, optical isolators, or opto-isolators.
Hysol GR17 cures with heat and can be used for transfer processes. It has been formulated to provide high moldability, low stress and high adhesion to a variety of substrates. Transmissivity is 18.5.

| Specific Gravity |
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.
For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

| Glass Transition Temperature (Tg) |
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.
The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
| Thermal Conductivity |
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance.
Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
|Transfer Pressure||40 - 85 kg/cm2|
|Transfer Time||10 - 15 s|
Store product in the unopened container in a dry location. Storage information may be indicated on the product container labeling.
Optimal Storage: 5°C or below, in closed containers. After removal from cold storage, the material MUST be allowed to come to room temperature, in the sealed container, to avoid moisture contamination. The suggested waiting time for a standard 15 kg carton box is 24 hours.
