Formulated to have special optical transmission properties, EP30-2LB is an optically clear epoxy that does not permit UV light transmission, but transmits well from 450-900 nm and above. It is a user friendly compound that has a non-critical ten to one mix ratio by weight. This system cures readily in 24-48 hours at room temperature or more rapidly at elevated temperatures. EP30-2LB is highly resistant to water, oils, fuels, acids, bases and many solvents. This highly dimensionally stable product has low shrinkage upon curing.
