Bob Smith Insta Cure

How long do I have to hold pieces together?

When is strong enough to handle?

Have 'gap filling' type.

Thanks!

According to the bottle of BSI Insta-Cure Gap Filling, it says 5-15 seconds. I know if you want to set it immediately, you can use the BSI CA Activator liquid and its done. If you do use this, make absolutely sure that you dont get the activator on or near the bottle of glue...you can only imagine how I might know this.

I've found that the times stated on the bottle are typically only for a general time-frame for when the product has started to "set-up", by no means does this mean it is fully cured to support weight. If you arent using the activator, I'd let it set for probably a full minute or so, just to be sure, before handling.

Just used some the same product to glue a photoetch gun shield this evening. It took about a minute before it set enough that the part could be sat down to dry.

When has it dried enough to hold weight if you want to

say it that way?

Testors isn't safe to handle weight until it's dried overnight.

If it is on something like the main gear on an aircraft model, I would probably wait overnight before actually trusting it to be fully cured.

I've never tried the Testors CA, but if you are referring to the orange tube glue stuff or cement, I'd give it maybe a couple of days for full cure.

I have switched away from using CA except for on PE and other hard to secure parts that needs help from CA activator. I personally like using a PVA glue as well for PE, in particular I use Gators Grip regular and thin formula. I like that it holds well, dries clear and is somewhat flexible.

I do know that there are some builders who use CA exclusively on their builds and have good luck that way. I've never had any luck with it myself using it for the entire build. My problem is that I've had a model literally fall apart when using just CA. I cant say that this has occurred using the Bob Smith brand, but typical stuff you can pick up at most stores doesnt seem to last for the long-term.

Maybe I'm expecting something else.

30 sec epoxy might setup and harden within another

30 min where it's almost as strong as it ever will be.

Bought some regular epoxy so I will see what that's like.

Epoxy cannot be dispensed in drops though.

Reread posts.

One minute and I can move on to next job.

I'll go with that.

See if I can finish up some of these started kits.Smile
