So my first time using Aluminite Clear. I love its fast cure time and hoping to fix the issue im having.
I made 2 molds out of dragon skin 30 and pressurized them. I mixed 12 grams of A and B and mixed good and poured in a new cup and stirred more before i poured into my molds that had no release.
I put these molds in my pressure pot and set at 60 psi and left it for 2.5 hours to be sure.
When i opened my molds they were solid white and still soft so im confused what happened. I mix these types of materials for a living so im stumped. Really could use some help. I normally use uv resins but want something i can do in transparent colors with polymer clay.

Lady Ann,
Typically the white cloudy, wispy white as some call it is caused by too much A side. It is typically resolved by the following two bits of information, Lady Ann. This is a weight measurement resin, not volume. Secondly, make sure you scales are accurate as sometimes it doesn't take much to alter a ratio (depending on amount you are using) to get this result. If scales are functioning properly, 1:1 by weight, then we can look at the mixing. When you are mixing making sure it is completely blended, scraping sides and bottom of mixing vessel well. When you scrap off the mixing stick on the side of the cup, make sure you mix it one more time to put back in the material what you scrapped on the side of the cup for a complete blend/mix. Once all that is tried, if you still have an issue, please let us know, you may call if you prefer.
The softness is more than likely a mix or ratio issue. To have a completely hard cure all the A's have to meet/combine with all the B's. This will create a chemical cross link for polyurethane exothermic 2 part resins.
Regards,
Carol

I tried again and did 12 of b and 10 of a and it was clear and harder. Not sure if i got a wonky batch or not. I put my pieces in a pressure pot and had some bubbles on the outside of the pieces. Going to try vacuuming and see what happens.

Lady Ann,
If the bubbles are on the outside of the pieces, it sounds like it could be a moisture issue. Urethanes are very moisture sensitive in their liquid state. These materials need to be used and stored in a climate controlled environment. Nothing water based for dying, fillers, encapsulation pieces, etc. Lady Ann how old is your material?
Regards,
Carol

Sorry just came back to this thread and trying this again. Its fairly new. May maybe?
I just got a new scale but it does not pick up small amounts. Bought a pressure pot to help with the bubbles. Now its just a coloring issue.
Thank you for the information.
I did watch a video on measuring this product so that has gotten better.

Consider adding a moisture trap to your Compressor before you fill your Pressure Pot.
