Black CA

Never seen the stuff before, but I know it wouldn't be of much use to me.  I use CA as my go-to seam/ejector pin mark filler, and then use a black Sharpie on the cured CA to act as a leveling indicator for when I sand it smooth later.  I sand until all of the black is gone, and then I know I'll have no more visible seam/pin mark.  If the CA itself were black, I'd never be able to tell when I had the seam leveled out with the surrounding plastic.  Not sure what those guys see as an advantage with black CA.

Over the last several months I've noticed many of my youtube heroes using black CA.  My go to CA is Loctite ultra control.  Is there any advantage in using the black stuff?  Maybe it's easier to see where to apply it?  Is there properties in the black to make it superior?

 

Seen it around, but haven't used it myself. I don't see where it would really make any difference.

Hello!

Until now I have only seen black CA being applied once - interestingly it was a girlfriend of my former co-worker who used it for professionally "doing" eyelashes... And I can tell you, the lady sure had a steady hand, imagine glueing fibres, human hair calibre a millimeter away from a human eye while taking care of proper geometry... Why somebody would want to have such operation performed on themselves is beyond me, but there were lines forming and money to be made on it so...

Now maybe that's the trick with using coloured CA - you don't have to paint it up after the glueing is done. I personally don't see the advantages here - I say the glue joints have to either be hidden or painted up anyhow. In the rare cases where I'm glueing stuff that won't be painted later I'm using some more forgiving glue anyhow - white glue or somethin'

On the second thought, if you think what would be desirable on this dang eyelash job (any special formulation) - like low fogging and stuff like that, maybe that would be good for us modellers, too - when glueing canopies or biplane rigging.

Thanks for reading and have a nice day

The stuff is supposed to be better for gluing soft flexible materials such as the tires on RC cars. It is a medium viscosity type CA. I've used it as a filler here and there, and for gluing single length flexible tracks on some AFV builds to test out that aspect. It works well enough in both types of usage.

Looks like I'll stick with Locktite and Bob Smith for the super thin stuff.  Thanks all.

Believe it's used mostly for seam/gap filling. It sands easier than normal CA.

It is another Bob Smith product. I used to get it at a couple of the local shops who carried the various BS CA glues with a shop name label attached.

Hey, Pawel!

    Maybe this is what I need for the Shark model I got. It's some kind soft resiny stuff. I have never worked with flexible main parts before!

I have to admit the idea of having any version of CA so close to the eye and its moisture gives me the cold chills...but more power to those who have that skill, I suppose.... 

I didn't know it existed...but I'll have to keep it in mind next time I'm doing vinyl or rubber parts, just to see.

I wonder if it would work on Delrin?

Bob smith does market a version of the stuff...they say its 'rubber toughened'.
