Alumilite mold putty- think I found Zubber

[mazinz]

A long time ago Zubber was a discussion on these boards because it was a rubber like substance and was a kids toy that could be pressed into molds to make rubber insects and such.

Here is that discussion and you can see my results with further info using this material on page 2 of that post:

Today I finally had a chance to go to a Hobby Lobby (and I must say the place is amazing!!). I found something there called Alumilite Mold putty and that can be seen below:





Now Zubber has technically bombed and disappeared off the store shelves. The problem with that, is it was an amazing on the fly and super quick flexible mold maker

So I was reading the box of Alumilite mold putty and it did seem to be a zubber like substance. I plunked down the rather pricy $30.00 and tried it out

This stuff is 99% exactly what zubber was. The only real difference is this was way less greasy and it did stick to a paper plate (zubber did not), but everything else is the same (same mix time, same cure time, etc). The instructions mentioned on how to do a 2 part mold and did go on to say that if you do this you need to coat the dry mold with Vaseline otherwise the material will stick to the already dry half. Zubber was the opposite of this and applying new zubber to old zubber would not stick

I just wanted to bring it out there for those that may have never heard of Alumilite's Mold putty previously and liked using zubber as a mold maker or even pressing it into your new/old Creepy Crawler molds to make new rubber whatevers that this substitute will work fine

I have used and experimented with both Zubber and Alumilite's Mold Putty. I think I was even the first to break the news here when Zubber first came out.

My findings have been that they are both good for an inexpensive quick push mold. However, They both have a very lousy tear strength. Meaning that over a short period of time the mold will likely be destroyed and you will have to make a new one. This especially holds true when working with making moldings that have intricate under cuts. When using this stuff be sure that you make your mold extra thick so that it will last longer.

FYI - For Hobby Lobby fans I would like to encourage you that do not know and remind those that already know to take advantage of the weekly Hobby Lobby 40% coupon found on their website.

So far to date this year Hobby Lobby has continued to have this coupon for the 40% off every week of 2012. (knock on wood) I hope that they continue to do so. Previous years the coupon would be like every other week and was kind of spur attic so one had to keep checking back. I am a very avid Hobby Lobby customer so I definitely put the coupon to good use time and time again.

Can the result be painted?

Thank you for the coupon and yes that was your post sir. However I never had the molds I made with the stuff go bad or rip, then again it is sometimes hard to see just how much of the crap you will need to cover your item, so I always ended up overdoing it and making large thick molds for a relative smaller object.

Anything I used the stuff with (mold or as a filler for a mold) still is in fine shape today. I have a feeling this stuff will last a number of years if not indefinitely

I have never found any paint that actually stuck to Zubber. However this stuff is less greasy so you might be able to get paint on it. Hmm then again if you coat this with the flex seal rubber sealant and if it does stick, you can then paint the flex seal rubber

I think you should add the pigment before it cures if you needed to have a specific color.

Not sure if that would work since the stuff is similar to silly putty in texture

No problem at all. Always glad to help out when I can.

You are absolutely correct. The thicker the mold the better. I made a lot of mine sparingly in the beginning as I was just experimenting. I tried to make a little go a long way. The end result was not very saving at all.

Trying to find a paint that would actually stick to the material was my biggest challenge. I never was successful at doing that and eventually put the project on the back burner to do other projects and tests.

Nice thought although I think the issue with trying to do that would be that you would end up having dye all over your hands from mixing/kneading it. That and I do not think that one would have time to mix it properly to get an even color distrubution before the stuff turned hard on you.

Rubber gloves might help with avoiding dyed hands...Heh!
