Product Q&A

Q:Why does platinum silicone rubber fail to cure?
A:
Platinum-cure silicone is sensitive to inhibitors. It will not cure if exposed to natural rubbers vulcanized with sulfur, RTV elastomers catalyzed with metal salts (e.g., tin compounds), epoxies catalyzed with amines, or certain organic solvents like ketones, alcohols, and ethers.
Q:Why are the bottom and sides of platinum silicone molds still gummy?
A:
This usually results from inaccurate or insufficient mixing. The material must be mixed thoroughly for at least 3-5 minutes. Ensure you scrape the container sides, bottom, and corners during mixing to achieve a homogeneous mixture.
Q:Why does the curing time vary with different temperatures?
A:
Platinum (addition) cured silicone rubber uses a platinum catalyst and is sensitive to temperature. While it can cure at room temperature, applying heat significantly accelerates the curing process, transforming the liquid to solid rubber more quickly.
Q:Is platinum silicone rubber food safe?
A:
Yes, it is safe for contact with food and skin. It is suitable for making molds for food items such as chocolate and fondants, as well as for making prosthetics.
Q:How should the two components be mixed?
A:
Mix components A and B according to the 1:1 weight ratio. They can be mixed thoroughly by hand or using a low-speed electric mixer to minimize air entrainment and avoid temperature increase. A special mixing and dispensing machine can also be used.
