How to make mold

This material can readily accept pigments.Stirring individual components before use is recommended. Make sure to weigh and measure accurately. Close containers tightly after use. Products should be stored in their original, sealed containers in an environment that does not exceed 90℉. Under these conditions, the product will achieve the expected shelf life.

The following procedure is an example of a 10:1 mix ratio addition cure product. Please refer to the product's technical sheet for mix ratio information:

Mixing: Charge 1 parts by weight of "Part A" and 1 parts by weight of "Part B" into a clean, compatible metal or plastic container. The volume of the container should be 3-4 times the volume of the material to be mixed. This allows for expansion of the siloxane material as it de-gasses.

Mix thoroughly by hand or with mixing equipment while minimizing air entra
pment until a homogeneous mixture is obtained. This will occur when the material takes on a uniform color with no visible striations. Scrape the sides and bottom of the container thoroughly several times while mixing. Once mixing is complete it is recommended that the material be de-aired 2-3 times by intermittent evacuation for a few minutes to minimize any imperfections due to bubbles in the cured material. Typically after releasing the vacuum 2-3 times the mass will collapse on itself at which time the vacuum should be left on only 2-4 minutes longer.
