What is the difference between tin-cure and platinum cure
The chemical difference between tin-cure (condensation cure) and platinum-cure (addition cure) silicone mold making rubbers lies mainly in the metal used to catalyze or cure the base rubber. The metal tin is used to catalyze or cure tin silicone, and platinum is used to cure platinum silicone rubber.
What is the difference between silicone and platinum silicone
Standard and food grade silicones are cured with peroxide. On the other hand, curing with platinum is more expensive, but the resulting silicone is cleaner and purer, and does not contain any fillers or byproducts. Medical grade silicones are cured with platinum – which is what we use.
Does platinum silicone inhibit tin silicone
Tin silicones are less expensive. Platinum silicones are more susceptible to chemical inhibition, so they often require a test cure before use. (Note: If you use a Tin silicone on a surface, you can no longer pour a platinum silicone against the same master due to inhibition issues.
Does tin cure silicone stick to platinum cure silicone
Tin cure and platinum cure silicones are not compatible and cannot be used together.
What inhibits silicone from curing
For example, applying latex, urethane or silicone rubber directly over a model made of clay containing sulfur will result in cure inhibition. The sulfur in the clay is preventing the rubber from curing.
What causes silicone inhibition
Inhibition can occur when a platinum-cure silicone rubber comes in contact with any of the following: Chlorinated solvents. Acetone, MEK. Adhesive tape (e.g., duct tape)
Does water stop silicone from curing
It's not recommended to expose the silicone to moisture before the caulk cures completely to ensure the caulk is completely waterproof. However, if you can't wait 24 hours, you should at least wait 12 hours. … This will ensure that the surface of the silicone is completely dry, and the water can't be completely absorbed.
What is platinum cure silicone used for
Platinum cure silicone, also called addition cure silicone, are two-component high tear strength and flexible mold or casting compounds. They are recommended as a mold material for casting polyurethane, epoxy, or polyester resins, wax and a wide range of other casting materials.

Is platinum a silicone medical grade
