RTV Silicone Mold Making FAQs:
What are the differences between the various liquid silicone rubber kits?
Different silicone kits are ideal for different sorts of projects. While some silicone kits may be best for molding plastic figurines or mechanical parts, others work well with pourable concrete. Silicone putty can be useful for materials that are not pourable, like a horse’s hoof.
The AM 128 RTV Silicone Rubber is our most popular liquid silicone for molds. It’s durable and tear-resistant, and perfect for those heavy duty jobs. You can also use the brushable variant for projects that might require vertical cling.
The AM 115T is translucent, so it’s perfect for those jobs that you need a little extra visibility on.
AeroMarine Silicone Accelerator is ideal when you need to speed up the time it takes for your silicone mold making rubber to dry and cure.
If you’re working with a project requiring enhanced detail, the Silicone Oil Thinner is perfect for making the pourable silicone for mold making better at getting into those nooks and crannies. If you have the opposite problem, there’s always the Silicone Thickener too.
When should I use latex vs silicone rubber molds for my project?
Latex and silicone rubber molds have varied uses that will depend on the sort of project you’re using them for.
Latex is only brushable, so projects involving making a latex cast of concrete, wood, or other hard surface is an ideal use for a latex mold. Latex also requires multiple layers to make a useable mold, so you may want to consider our Black Powder Rubber Extender and Filler to make that latex you bought go a little further.
Silicone is sturdier, more durable and tear-resistant, and long-lasting. Silicone also comes in a number of different formats; if you need to paint the silicone on, our brushable silicone is a good option.The general mold-making AM 128 RTV is sturdy and pourable, and can be poured into a plastic or cardboard frame for convenient later use — it’s our most popular silicone rubber mold making kit.
For projects where pourable silicone is not necessary, we offer a fast-drying Silicone Rubber Putty.
Are all options of liquid silicone safe for food applications?
Unfortunately, not all liquid silicone rubber molding is suitable for use with food. If you’re making molds that you plan on using for food (like chocolate molds or even ice trays) you’ll want to check out our Food Grade Silicone Rubber. It’s FDA-approved and specifically developed for use with consumable materials.
