Optically clear encapsulants provide durable clarity, high product yields, superior process characteristics and high reliability for applications including image sensors, photo detectors, infrared devices, and LED displays.

SolEpoxy optoelectronic encapsulants provide moisture resistance, thermal shock durability and excellent color stability even in outdoor applications and at elevated temperatures. Superior color stability through UV and thermal aging is the hallmark of SolEpoxy optoelectronic encapsulants.


Unique Characteristics

Transmission properties can be tailored to specific wavelengths and our proprietary resin system provides outstanding resistance to yellowing even after extended exposure to UV light. We call this "Durable Clarity."

It's because, unlike other clear molding compounds the MG18 and MG97 family of products do not contain aromatic compounds. When exposed to UV light, most aromatic compounds form unstable free radicals which degrade the polymer and cause yellowing.

Color stability is crucial to devices that emit UV light such as VCSELs and white LEDs, as well as in outdoor exposure applications. Long-term thermal exposure may also cause discoloration when aromatic compounds are present. Superior color stability through UV and thermal aging is the hallmark of SolEpoxy optoelectronic encapsulants.
