Low viscosity, electrically insulating epoxy boosts optical clarity

MASTER BOND EP30LP-2 two component epoxy with a low viscosity and a volume resistivity of over 1014 ohm-cm making it suitable for potting and encapsulation applications. The high performance system can also be used for bonding and sealing. The easy to handle compound has a convenient two to one mix ratio by weight or volume. A 100 gram batch has a 60-90 minute working life at room temperature, which can be extended by using shallower mixing vessels or mixing smaller size batches. System is formulated to cure at room temperatures or more rapidly at elevated temperatures.  http://www.masterbond.com/properties/optically-clear-polymer-adhesives
