OE-6662 and OE-6652 phenyl silicone optical encapsulants are two-part, heat-curable products for improved reliability, anti-silver corrosion and durability for light-emitting diode (LED) designs. Offer Shore D 64 and Shore D 59 levels of hardness, respectively. Improved gas barrier performance protects delicate Ag-plated LED electrodes from sulfur attacks. In addition to inhibiting degradation of light output efficiency, this can extend the overall quality and lifetime of advanced LED designs.
