Bill_Adcock Posted November 19, 2005 Share Posted November 19, 2005 I'm assembling a steam tank for a Steampunk game...the chassis and treads are resin, with pewter smokestack, gun, and hatch. I get out my trusty Krazy Glue, but it doesn't seem to be forming that great a bond between the chassis and one of the treads. Is the glue the problem?

eastman Posted November 20, 2005 Share Posted November 20, 2005 did you wash the pieces first? the silicone mold release agent used for resin casts needs to be washed off before glue or primer will stick. if you did wash it, you might need a different type of cyanoacrylic. I have had better luck using the gel than the the more fluid type. Quote Link to comment Share on other sites More sharing options...
Stern Kestrelmann Posted November 20, 2005 Share Posted November 20, 2005 BA- You might also try pinning the pieces together in addition to the glue. SK Quote Link to comment Share on other sites More sharing options...

Enchantra Posted November 20, 2005 Share Posted November 20, 2005 I...uh...guess I'll try washing the pieces then. Yes by all means wash the resin. Wash the pewter pieces too. You'll be better off for it. When you have all the pieces washed and dried, I would glue the pieces together with a gel cyanoacrylate glue and pin it also. I had a problem with the Earth Elemental I painted up for The Figure Trader back a couple months ago. I had washed him and rubbed him down with alcohol for good measure and I couldn't get the arms to stay put. I ended up pinning him really good to get the pieces to stay where they were supposed to go. So pinning will help after you have washed the pieces.

Joe Kutz Posted November 20, 2005 Share Posted November 20, 2005 Did the Krazy glue "melt" the resin at all? If it did - than it should work, and you might just need to switch a thicker glue to get a better hold while it sets up. If the glue didn't do anything to the surface - than you propably have a polyurethane resin and need to use a isocyanate glue. I get mine from an industrial supply shop here locally - but I am sure they have a few name brands that you can find in hobby shops. Quote Link to comment Share on other sites More sharing options...
Bill_Adcock Posted November 20, 2005 Author Share Posted November 20, 2005 Okay, so now I have to buy isocyanate glue...bah. Quote Link to comment Share on other sites More sharing options...
Joe Kutz Posted November 20, 2005 Share Posted November 20, 2005 You don't have to buy isocyanate glue, but it works better than super/krazy glue formulas on urethane resins. If you only have the one you can get away with adding some tooth to the two surfaces which will be glued together (using sand paper, needle files - even an bladed tool). Rough it up a bit, glue, press together and let it go the full cure time before trying to mess with it. Should hold well enough. Quote Link to comment Share on other sites More sharing options...
Mourningcloud Posted November 22, 2005 Share Posted November 22, 2005 Also it could be that your crazy glue is too old. Most people dot realize that that stuff only really has a life of about a couple of months after you puncture the tube and it gets exposed to air.

haldir Posted November 23, 2005 Share Posted November 23, 2005 anther good option is to rough up the areas where the glue joint will be, giving the glue something to bite into, use sandpaper or something similar. Also a little glue accelerator never hurts either. RM Quote Link to comment Share on other sites More sharing options...
