Where you need a convenient, easy to use optically clear adhesive for a
critical situation then the Opti-tec 5013 two pack epoxy from Intertronics
offers high optical clarity and fast room temperature cure. It is designed
for assembly/repair of glass, quartz, metal, plastics, wood or ceramics in
applications such as optical filters, lenses, prisms, opto-electronics, e.g.
photonics and LEDs, artwork and sculpture, as well as encapsulation, glob
topping, casting and potting - and it is highly effective in restoration of
minerals, gems and quartz crystals.
Opti-tec 5013 features a high surface energy which allows it to wet and wick
between surfaces, although its medium viscosity makes it easily handlable.
Within minutes this two pack sets in place (can be handled in 30 minutes)
with full cure achievable in 10 mins at 65°C if required. After cure the
Opti-tec 5013 joint is hard and capable of being polished. It is water white
clear, to make it virtually invisible in many applications - such as a
recent example reported by one customer:
This involved repair of an exhibit quality quartz crystal, which was
achieved without special fixturing due to the fast cure. Since the
refractive index of Opti-tec 5013 epoxy exactly matched the quartz, the
repair lines were completely invisible.
