TPR: I need to find or create a solvent based glue for TPR. Is there something I can purchase that will chemically bond TPR to itself? The application is a simple TPR molded sample we got from china, we had to cut it open to get to the electronics and now we need to glue it back together. UV cure-able polymer/urethane: I'm working on a personal 3-D modeling machine (not a 3D printer) and I'm wondering if someone can help me out with developing a transparent material that hardens to anything greater than shore D 75 durometer when exposed to UV or near UV light. The cure time must be instant, and curing must be able to take place where no oxygen is present. For example, if I turn on a UV LED and submerge it in the UV liquid, it should polymerize around (coating) the LED. Thank you in advance. If there is a better place to ask these questions please let me know.
