SiSiB® HF2083 is primarily used as a crosslinker for addition-cured silicone elastomers, imparting superior properties to the end product, including strong aging resistance, excellent UV stability, and no yellowing even after extended use.
In the LED industry, SiSiB® HF2083 is commonly used for potting, bonding, and encapsulation. It is particularly valuable in the production of silicone encapsulation materials for high-power LEDs, as well as potting, sealing, bonding, and coatings for the optoelectronics, electronics, and microelectronics industries. It is also used to develop high-transparency, high-hardness lenses and other specialty applications.
SiSiB® HF2083 is supplied in 20Kg plastic drum, 190Kg steel drum or 900Kg IBC tote.
In the original unopened packaging, SiSiB® AF8250-15 has a shelf life of 24 months in a dry and cool place.
