How long does it take for the silicone to cure?

It cures to flexible rubber within 6 hours at room temperature, or faster with heat. Demolding is advised after 24 hours for better replication.

Product Q&A

Q:Why does the curing time of platinum silicone vary with temperature?

Platinum cured silicone is sensitive to temperature. It cures quickly with heat but can also be formulated to cure at low or room temperatures.

Q:Why are the bottom and sides of platinum silicone molds still gummy?

This occurs if mixing is inaccurate. The material must be mixed thoroughly for at least 3-5 minutes, scraping the container sides, bottom, and corners.

Q:Why does platinum silicone rubber not cure?

It is sensitive to inhibitors like sulfur-vulcanized natural rubber, tin-catalyzed RTV, amine-catalyzed epoxy, and certain solvents like ketones or alcohols.

Q:Is platinum silicone food safe?

Yes, it is safe for contact with food and skin, making it suitable for food molds and prosthetics.

Q:What is the recommended mixing ratio for Part A and Part B?

The ratio is 100:2 by weight. Part A should be stirred thoroughly before mixing evenly with Part B CA30 Curing Agent.
