With the proper release, you can cast Alumilite into almost anything. Here are a few examples: Silicone, Wax, Non-Sulfur Clay, Urethane, Latex, Plaster, Steel, Aluminum, and Wood. A thick paste wax or the Stoner Urethane Mold Release is required...
The catalyst is the curing agent for 2 part room temperature vulcanizing (RTV) silicones.
Tensile Strength...is measured by grabbing two ends and pulling them apart until the part breaks. This measures the tensile strength and also gives you an idea of how elongation by measuring how much it stretches before breaking as well. Pot...
Silicone rubber has a 1 year shelf life, but similar to the urethane resins, moisture is the cause of problems and will affect product performance. So it is important to store your silicone rubber in a clean and dry place to maximize the shelf...
To replicate tires, use a high strength tin base silicone mold making material to make a 2 piece mold of your original. Flex 80 casting resin with Black dye works great to reproduce the tire itself. You can use softer Flex series products if you...
The rule of thumb is this; silicone bonds to nothing but another silicone, Alumilite resins bonds to everything but silicone! When pouring RTV silicone against any non silicone surface (exception: a porous surface, such as wood, it would need to...
Yes! To aid in the release of silicone rubber from your mold box or your original, use a small amount of rubbing alcohol. The rubbing alcohol will make the cured silicone very slippery and will help seperate the silicone from the other surface....
If casting into a silicone rubber mold, it is usually not necessary to use a mold release because of it's natural no-stick tendencies. If in doubt, Alumilite offers a Pol Ease Release 2300 that will not only help release your part but will also...
Tin silicones like warm humid environments to cure in. To help the silicone cure, take a wet a washcloth or hand towel and place it in the microwave. Warm the towel until it is steaming. Open the microwave door and place your mold box in there (do...
Pol-Ease 2300 Release Agent is a good option and should provide a good release interface. PVA may be a good choice as well, but you'd want to test it for your specific application.
There are approximately 21 cubic inches per lb of silicone rubber. This will give you an idea for whatever size mold box you need. To answer you question more directly ... 1 lb is approx 16-17 fl oz. The 10 lb kit is a little bit more than a...
You will need an artist brush (natural) to paint a thin/skin coat onto the original. It is not the idea to cover the object with this first layer, but to push the silicone into the nooks and crannies filling in all the fine detail. This first...
If you are using one of the FDA silicones for food molds, do not use any harmful chemicals for clean up. Instead, wipe surfaces several times with a soft cloth or paper towel until a very thin film remains and then finish cleaning with rubbing...
Silicone Fluid otherwise known as silicone oil thins the viscosity for unmixed silicone making it easier to pour. It will also slightly lower the hardness of your cured silicone system. The silicone oil can bleed from the cured RTV rubber if too...
Many factors need to be taken into consideration, so this is difficult to answer with a specific time. The primary factors that play a role in the life of a silicone rubber are what the rubber is being used for, what casting medium is being used,...
Generally speaking, our silicones have a very long shelf life. We've used as well our customers have informed us they have used our silicones very effectively after sitting for years. The official shelf life of all Alumilite's silicones are one...
When measured accurately, mixed thoroughly, and cured properly, many of our materials with FDA standards. Even though these silicones can be washed, it is highly recommended to designate molds that are to be used for food as food only molds. DO...
Silicones pick up the exact detail of the original including flaws and imperfections. So make sure your master is exactly how you'd like it prior to pouring. Fingerprints and scrim shaw are examples of very fine detail that are captured using our...
Our customers have both molded and cast very large items such as entire walls, bars, museum pieces, sculptures, trees, stairways, and architetural reproductions to name a few. Most of the materials are the same however the processes may change....
Vacuuming: A vacuum pump is like a vacuum cleaner. A vacuum cleaner is designed to pick up things such as dirt off of carpet using suction or vacuum. A vacuum pump is identical to a vacuum cleaner, except it will have MUCH more suction. A vacuum...
Using mold release before pouring parts can double the life of your mold. Over time, the silicone oil will absorb into the silicone rubber mold to replenish some of the oil that has been lost during normal casting and demolding of your parts. The...
This all depends on the intricacy, what material you are pouring, and the detail of the part. Other factors are how many undercuts and how well the mold is cared for. It also depends on how often you are pouring, how hot your mold gets and if they...
Tin based silicones can be poured over anything and they will cure properly. If pouring over another silicone, a rubber to rubber mold release will need to be used to prevent it from bonding. If you do not have a rubber to rubber mold release,...
Tin-based silicone (condensation cure) uses tin salts as a catalyst, releases byproducts during curing, and has a shorter lifespan with slight shrinkage. It’s commonly used for general mold-making but isn’t ideal for long-term or food-safe...
