I am still curious if naptha alone works on a properly cured part.. gonna give it a try…

In reply to Darrel Somoza. For me it was a matter of getting exact, repeatable tolerances on infuriatingly small, complex parts with mirror finishes. The size difference during silicone curing and the texture left by the release agent wouldn't have been acceptable, and any sort of sticking when double casting would have likely ripped the small details. Normally, though, this would be a great way of doing it!

Why go through all that trouble? Simply double cast. First in Mold Max then in Mold star.

Someone did an experiment with resin printed dice that had been sitting around for 2 weeks. He was testing to see if Inhibit-X was just naphtha. He had a control, Inihib-X, and just naphtha. The control came out normal with no mold curing problems. He then made new dice and then immediately made a mold and had curing problems.

So waiting a couple of weeks will fix the problem and eliminate curing problems.

Hi Josh,

This is a really awesome write-up as I’m facing the same challenge when attempting to cure platinum silicone in an SLA mold. This is a critical part of a business model I’m working on.

Does the Mann Inhibit X work for multiple mold pours, or does it need to be reapplied each time?

Have you learned anything new since creating this post?

Thanks for taking the time to make this post
