If you are looking for an adhesive with a RI of 1.5, you might
choose either Hxtal Epoxy or Paraloid B-72.  Either one are closer
to RI 1.5 than Opticon UV-57. (Hxtal is around 1.52; B-72 around
1.48-1-49, and UV-57 around 1.53).  See

    Tennent, N. and Townsend, J.,
    "The significance of the refractive index of adhesives for glass
    repair"
    in Adhesives and Consolidants, IIC Paris Congress, 1984, pp.
    205-212.

The address for Opticon UV-57 is also given in that paper, as

    Opticon Chemical
    P.O. Box 445
    Palos Verdes Peninsula, CA 90274
    USA

What exactly are you repairing? That would influence my choice.
