Platinum silicone rubber for mold making is a higher grade silicone compare with tin cure silicone, as it is food grade and medical grade for some types, better performance and durability,
But as it uses Platinum as catalyst system, the silicone is quite sensitive with several elements, like:

Nitrogen, Phosphorus, Sulphur, Plumbum, Tin, Mercury, and Arsenic.

These elements will cause platinum silicone face the cure inhibition problems, which you will see the silicone mold is partially cured and partially not cured, or the contact surface with the copy item is sticky or gooey,
And among those elements, in our daily lives, Nitrogen, Phosphorus and Sulphur often appears in detergents like sanitizer, cleanser or liquid soap etc.

And Tin mostly the hidden culprit for the cure inhibition, is being ignored!

Most experienced mold makers used or started with Tin cure silicone for mold making in the past, but did not know that.
