What is the best temperature to cure silicone?
Single component silicone adhesives require a humidity of 5% to 95% to cure. Besides the presence of humidity, a temperature of between 40 and 100oF (5 and 40°C) is required to cure the adhesive.
How long does 100 silicone take to dry?

Wipe it with a soft cloth to be certain. The caulk also has to be completely dry before putting another layer on top.
How long does it take for silicone mold to set?
Normal curing time for most silicones is between 18- and 24-hours, but cure times may be greatly reduced by using fast-acting catalysts. When making molds in a studio where such equipment is available, de-airing in a vacuum chamber is recommended to remove trapped air bubbles.
How do you remove high temp silicone?
DIRECTIONS: Remove heavy silicone residue using Permatex ® SaferScraper ™ . Spread liberally on surface and let stand for several minutes to soften gasket material. Allow longer contact time for thick layers. Wipe material with a clean rag or scrape from surface with Permatex ® SaferScraper ™ .
