Resin gluing
Posted by Wylde on Wednesday, December 11, 2019 10:04 PM

I am building a bunch of cars from resin parts I casted but I am having difficulty glue the pieces together. What should I use?

Thanks in advance

First question, and I must ask, are you washing the parts? Even if you didn't use a mold release, tiny amounts of oil in the mold itself will coat the resin castings. This can affect painting as well as glue bonds.

Next, resins do not react to average model glues. Styrene glues bond by actually melting and welding the pieces together. Resin doesn't want to play that way.

You'll need super glue of some type. I prefer Gorilla glues as they have a dozen types of glues as well as that many types of applicators. 

Anyway, a super glue (cyanocrylate) or epoxy (2 part) glue is necessary to get any lasting bond.

As for Gorilla glues, I prefer the slow set super glue in a bottle with a brush and their super glue gel.

The brush seems a little clumsy at first but once you get used to it it's surprisingly versatile.

The gel is different from most in that for some reason you have to shake it before use. Annoying to be sure but, more like sand in a wet bathing suit, not tropical skin rash irritating. Anyway, it squeezes out a tiny drop compared to it's nozzle size and, has a tiny resevior cup at the tip I use to get spots of glue on a toothpick tip. 

If you try it though, never leave the cap off more than a couple minutes. When the tip becomes a little gummy? Leave the cap off for two minutes and wipe with a little tissue. Cleans it right off. Do not let the tissue get glued to your fingers! This will cause your friends and family to make fun of you endlessly. 

Don't ask how I know, just be glad the research has been done. ;)

Good questions. Thumbs Up

Been doing resin for many years, casting my own parts as well as building resin

kits, and have a nice collection still waiting for some love.

I like to start out giving all my parts a bath in BLECHE- WITE by Black Magic for 24 hours, followed by a bath in liquid detergent, then air dry.

As far as gluing, I have a favorite Hobby Town brand GAP FILLING super glue with a purple label, and ZIP KICKER by PACER, that instantly sets the super glue, all from Hobby Town hobby shop.

It's a nice combination of products I have use nearly 15 years.

Working with resin can be a lot of fun once you get to know how to work with it, like styrene.

There's a learning curve so be patient and it'll come to you Cool.

Good luck on your project.

What do you recommend if you are adding styrene parts to a resin body? I want to add the firewall and inner fenders from a plastic model to a resin body. The resin body firewall is just a big chunk of resin with poor detail.

I would use CA or Superglue if you are adding styrene parts to resin.  Model glue will not work on resin.

I would agree with mrmike  Thumbs Up.

Gluing resin to styrene or styrene parts to resin - use superglue.

Both ways work great. Just mke sure the resin has been cleaned properly.
