I need a bit of help

[papaturner]

I use polyester resin when I cast. I have cast arrow shafts to create a camo effect,and I have cast combat ribbons. No real problems with them.

Now I want to cast some labels. Have not had much success. My problem is the PR does not seem to stick to the label or the label does not stick to the tube. Some times both problems occur with the same pour.

My process goes something like this. I prepare the tube by sanding,I then attach the label,I prepare the tube for the mold,next I warm the PR to about 100 degrees before mixing with the catalyst, I then mix the catalyst in the PR and pour in the mold. Let cure about 24 hrs. before I remove from mold.

Any help or suggestion will be reatly appreciated.

We have not done labels, but didn't I read they cover the label with glue first?? And let set for a couple days.

It came up frequently in search for label casting and the author knows a few things about casting, I am told!!

You don't necessarily have to cover the label with glue but most times you have to put some type of sealer on it. I bought a label sealing spray from Hobby Lobby when I purchased some supplies. I think you can also use lacquer spray.

If you seal the label, I think the PR will adhere stronger. I also wait for a day after putting the label on the tube before I cast. It seems to minimize air leakage from the label during the curing process.

The longer you wait between casting and turning, the harder the PR will cure also. Have you thought about post curing with a toaster oven?

Just some other things to think about.

Here is how I do labels. I use Avery 8253 labels(10 per page or the Avery full sheet and cut out the printed art work). Avery labels seem to work best and the 82xx series seem to work best for me. I paint the tubes with Rust-Oleum Painter's Touch wet or dry sandable primer. I paint the tubes with white and let the paint dryh for a couple of days. I stick on the labels and roll the label on the counter top to make sure they are nice and tight to the tubes...really stuck well. I pay close attention to the edge of overlap. I allow the labels to sit for a day or so for the label glue to get good and dry, then I cast as described in the post mentioned below. I do not coat the labels with any kind of sealer and I've had no problems at all. I have not experienced any of the problems that are frequently discussed here about label casting. Guess I'm just lucky:biggrin::biggrin::biggrin:

I did have a reason to coat some real stamps and I used Mod Podge and it worked fine. I've only used it once. Happy casting.

Thanks Ed...
Do a good turn daily!
