Silicone Sealant: Silicone Oil, Diatomaceous Earth and Methyl Triacetoxysilane (Ceyzeriat 1964)
A one-part silicone that stays a paste in a sealed tube and turns to rubber in the open air. The moisture in the air splits the methyl triacetoxysilane, which then ties the hydroxyl ends of the oil together. Louis Ceyzeriat of Rhône-Poulenc made it with diatomaceous earth as the filler; his Example IV paste became an elastic solid in 15 hours.
Source: L. Ceyzeriat (Rhône-Poulenc), US 3,133,891 (1964), Example IV and columns 3–4. His filler was Celite 350; we use raw diatomaceous earth in its place. Picture drawn by Youblob.

Knead the paste
Knead 200 parts of hydroxyl-ended silicone oil with 80 parts of diatomaceous earth and 1 part of zinc oxide until it is an even paste. All parts are by weight.

Drive out all moisture
If the sealant is to be kept, it must be made dry: a paste with zinc oxide especially needs this. Heat it in the mixer at 50–200 °C, stirring, until every trace of moisture is gone, then let it cool. The patent gives that range, not one temperature or time.

Mix in the silane
Add 3 parts of methyl triacetoxysilane for every 100 parts of paste: 8.4 parts for the whole 281 parts (our arithmetic). Keep the air out while you mix.

Without letting any water in, fill it into dry containers and seal them airtight. Kept like this it stays usable for many months.

Spread or press it where it is needed and leave it in the air. Ceyzeriat's paste was an elastic solid after 15 hours. Pressed as a 2 mm sheet it tested 25.6 kg/cm² in tension, 290 % stretch and Shore A 50; after 24 hours, 39 kg/cm², 260 % and Shore A 58.
