ADHESIVE BONDING
Adhesive bonding is used to fasten two surfaces together, usually producing a smooth bond. This joining technique involves glues, epoxies, or various plastic agents that bond by evaporation of a solvent or by curing a bonding agent with heat, pressure, or time. Historically, glues have produced relatively weak bonds. However, the recent use of plastic-based agents such as the new “super-glues” that self-cure with heat has allowed adhesion with a strength approaching that of the bonded materials themselves. As a result, gluing has replaced other joining methods in many applications—especially where the bond is not exposed to prolonged heat or weathering. A large fraction of modern glues are carbon-based petrochemical derivatives. These can be used to bond almost any combination of surfaces, either by direct contact or by fastening both surfaces to a third as with adhesive tapes. Glues can serve as bonding agents in strong structural materials—one of the earliest, and still common use is the fabrication of plywood. Other related composites include fiberglass and various fiber-epoxies such as boron-epoxy and carbon-epoxy.
In the past,about 40 years ago, dentistry replaced self cured, tooth colored resins with uv light cured resins to fill cavities. Self cured meant chemically cured and the resin darkened with age. Light initiated curing had the advantage of being color stable. However, uv light has limited penetration through tooth structure, hence the newer high intensity light cured systems. All that being said, it does not relate to the "gluing" ability of the product.
As stated in adhesives.org, there is the adhesion to the surface of what is being glued, the internal strength of the glue, the material being glued. Remember using tube glue to put plastic models together? If you put them together immediately they stayed but years later the glue seemed to dry and the model fell apart. Then you learned to wait to give the glue time to soften the surface, pushed them together and actually "welded" the parts. Liquid cements let you assemble the parts first and would weld by melting.
For your self written quiz learn weld vs solder vs glue. For extra credit find out why there is the need for different plastic glues.
Bottom line uv gives the advantage of setting when YOU are ready, other than ambient uv starting the set. It says nothing about the ability to attach parts with longevity. I would stick to epoxy or superglue. You could try soldering, there have been articles on solder repairs of flat figures! You just need to be excellent or love blobs.
Sorry I got carried away in my response.
