Estes plastic parts RTF
Estes RTF plastic parts.
A while ago, in search of a model R/C aircraft, I came across some model rocket parts. It was fin can and N/C. I made a rocket from it. The fin can broke a fin and I tried to glue it back on. The glue did not take. The fin can will not take plastic glue. So... What do I use? Thanks in advance.

Some plastics are just not "repairable", unfortunately.
Do you know what kind of plastic it is ? If you did, I would be able to suggest a bonding agent.

Quote:
Contact cement will glue anything to itself, or to anything else--but it grabs *instantly*, making proper alignment of the "to be joined" parts vitally important. Ditto for cyanoacrylate (i.e., "Super Glue"), which also bonds as soon as the parts are pressed together. Epoxies--especially the ones with longer curing times (longer "pot lives"--they are also much stronger than the five-minute stuff, when cured)--also ought to work; so should polyurethane glues, which are sometimes, but not always, two-part bonding agents, like epoxy. (The two-part polyurethane casting resins [or epoxy casting resins, too], such as Alumilite, Por-A-Kast, Polytek, etc., are also effective bonding agents, as I've found [their documentation also mentions this use].) But: As Stine also mentioned in his book, there are some plastics--such as PVC, and other, "waxy surface-like" ones--that are "resistant," so to speak, to commonly available bonding agents; but even for these plastics, there are--as he also wrote--specialty bonding agents available. LOCTITE (see: https://www.loctite.com/loctite-location-selector.html ) offers multiple formulas of Industrial and Consumer (there's a separate webpage on their site for each category) epoxies--most, but not all, in their famous dual-syringe dispensers--that are formulated to bond many different types of plastics to themselves, and to other materials.
