Hysol GR180R | White Epoxy Mold Compound

Harmonization Code : 3907.30.00.40 | Epoxy Mold Compounds containing by weight more than 70 % silicon dioxide

Hysol GR180R | White Epoxy Mold Compound

Main features

  • Reflective compound
  • High reliability
  • Great workability

Product Description

Hysol GR180R is a white, reflective epoxy molding compound used for optical applications. This fused silica filled (76 - 86%) product has been specifically designed to improve light reflectance and workability for optocouplers also knows as photo-couplers, optical isolators, or opto-isolators.

Hysol GR180R cures with heat and has a filler cut size of 75um that is ideal for transfer processes. It has been formulated to provide the best possible moldability and for a wide range of molding process parameters.

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.

Thermal Properties
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.

Additional Information

Storage

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.
