Hi Todd,

For more information on UV epoxy resin 3094, see below.
It is now produced by another company, the new name is Dymax 3094.

AI Overview
"UV epoxy 3094" refers to different products from different 
manufacturers, specifically the Dymax 3094 and ThreeBond 3094, which are 
both UV-curing adhesives used for plastic and medical device bonding, 
respectively. The Dymax 3094 is a low-stress adhesive for plastics like 
PMMA, PC, and PS. The ThreeBond 3094 is a high-viscosity, UV-curing 
resin with good adhesion to polycarbonate and acrylic, used for medical 
device assembly, and is biocompatible according to ISO10993 standards.
Dymax 3094

Thank you,
Albert
