Cure Characteristics:

The curing process begins as soon as the catalyst is mixed with the base.
Under normal temperature (77F/25C) and humidity (50% RH) conditions, the material will cure as described in the data above.
Any large change in temperature (+/-5C) or humidity (>60-70%) may alter the cure profile of the material.
You can accelerate the cure with mild heat; 150F at 1 hour per inch of thickness.

HOW-TO:

Items Needed:

You will need an original part, clean mixing containers, mixing utensils, and a mold box into which to place your piece while making your mold.
A mold box can be made out of almost anything, including a reusable food container, cardboard, wood and Legos.
You may also need a digital scale, a glue gun and/or clay.
Depending on the size of the piece, 1/2″ of silicone mold-making rubber is the minimum thickness necessary for the walls of your mold.
- Making it too thick will reduce the flexibility of the mold, while too thin will reduce the resistance to tearing.
Silicone RTV mold making rubber may soak into a porous surfaces like wood or plaster. To prevent sticking, first seal the part with a sealant appropriate to the material.

Measuring & Mixing:

Shake the catalyst very vigorously for 60 seconds before weighing it.
Weigh parts A and B accurately (10:1 by weight).
Once you have correctly measured both parts, mix parts A and B together with a plastic or wooden stirring utensil.
Take care to scrape the sides and bottom of the mixing container.
Keep your stirring utensil on the bottom of the container to reduce the amount of air being mixed into the silicone.
Mix for several minutes, scraping the sides and bottom frequently, until the silicone is one uniform color with no streaks.

Pouring Silicone:

When pouring your silicone, do NOT pour it directly onto the part. Instead, pour the silicone into the shallowest part of the mold and let it find its own level. This method prevents air bubbles forming on the surface of your part.
Storing Your Cured Silicone Mold (Storage longer than 1 week)
- First, apply mold release to your cured mold.
- Second, pour your casting material into the prepared mold. Or, you can insert a previously cast cured piece into the prepared mold.
- Third, put your mold (if a smaller mold) with the piece in it into a doubled “Ziploc” type bag with all the air pressed out of the bags.
- Fourth, seal the bags tightly closed using either a plastic bag sealer or over-tape them with duct tape.
For larger molds, use very heavy duty doubled garbage bags, remove all the air and seal tightly either with a plastic bag sealer or over-tape with duct tape.
- Finally, put your sealed, bagged mold into a plastic storage container with a lid, close the lid and store on a flat shelf/surface (NOT the floor or window) at continuous 70F out of direct sunlight.

Cleaning Silicone Molds for Use:

Wash your cured silicone mold with warm/hot water and mild liquid dish soap.
Pat dry thoroughly and then let the mold air-dry fully.
Never use any type of abrasive soap, cleaner or pad to clean your silicone mold!

Tips:

Not suitable for making food storage containers.
Not use for making baking or microwave pans.
Shake catalyst vigorously for 60 seconds before using.
Wash the cured mold thoroughly with warm water and liquid dish soap before use.
