I use this rubber to produce moulds from purple resin out puts
(viper) of my CAD designs. I religiously follow the instructions,
but some thing seems to go wrong and the result one lump of half
done rubber mold and the resin master spoilt. If some one can
explain step by step the process I will thank him/her for saving my
time and energy,and almost giving up on a good product.

Sorry, I haven’t used the resin your referring to, only the white
resin output from Stereo Lithography.
I went back to the Castaldo WebSite to try and find a clue, No Joy.
However it did raise the question regarding the use of Clean Mold
Frames and other contaminants. It appears that it is not forgiving
when it comes to mixing with other types of rubber. As I recall, the
ones that I did I followed the instructions meticulously since I try
for repeatable results and it’s just part of the ritual.
So having said that, I picked up the phone and called Mr. Knight at
Castaldo to give him a heads up to your message in case he missed
it. I believe that he monitors the forum, again, No Joy. He is on
Vacation for a couple of weeks and no one else could answer the
I did leave a message for him to check the forum when he returns.
BTW if you would like to contact me offline, I’d be more that happy
to try and experiment with your resin if you have something you can
