I need some help with mold max. What do the numbers mean? I need to make a simple mold so I can pour some PR. Ive narrowed it down to MoldMax, but which one?
Which is the Moldmax the mold folks use? MM30,40,20,25,27???????

Tried using Si caulk but that was a mess for me......:bad:

I'm too late to the party. Yes, it's the Shore A hardness of the silicone.
That's a durometer rating system. Keep in mind that this hardness will
change if you alter the mixing instructions. 25-30 are fairly soft numbers.
70 would be like the tread on a car tire. Ebonite would be around 100.
 
Sorry Charlie....... Party's done.

So would a MM 40 be ok for the puzzle pieces you lazered? and at the same time have a little left for a single WW mold?

That should work .. although if you haven't purchased yet, I'd go with the
30 .. it just works better for the smaller things we do. If you're making
a larger mold (5x5, 6x6 etc.) then the 40 will give you more stability if you
go higher than an inch or so. But either one will work.
 
I have best longevity using 27 T clear. 40 is pushing it, 60 is so hard its brittle. Be sure you measure mix and stir it completely...electric mixer a good idea. I use a spade bit in my drill, groung spurs off the bit of course, works super
