homemade silicone rubber
The invention of RTV (room-
Silicone changed this and allowed to make homemade items with silicone rubber.
These RTV silicone can be purchased at many art and industrial suppliers.
Silicone rubber that is not formed is not very interesting, so you usually pour these ingredients into the mold to make a statue or other shape.
Place the paper bucket on the scale and reset the scale to zero.
Pour some silicone bases into the paper bucket for weighing.
To get the most accurate mixture, you should weigh in ounces or grams.
Add the correct amount of catalyst to the alkali.
Most silicone uses a ratio of 10: 1 for alkali and catalyst, but the label on the silicone is to be checked to ensure.
If the ratio is 10:1, simply divide the alkali weight by 10 to determine the amount of catalyst to use.
For example, it takes 7 grams of 74 grams of alkali.
Mix the catalyst completely into the base.
Most silicone bases are white, while the catalyst is dark blue or green, allowing you to visually ensure that the two ingredients are mixed together.
When you work, scrape the sides and bottom of the bucket several times.
Take your time--
Most RTV silicone takes several hours to solidify.
Pour the silicone into a mold, cookie sheet, or other container to solidify.
If the container is made of silicone, you must first brush a thin layer of hand sanitizer for release as a mold.
No release is required otherwise.
