Silicone Rubbers

Silicone rubbers (both liquid and paste versions) are used to create molds for reproducing a wide variety of objects. They are compatible with virtually any material: epoxy resins, concrete, wax, metal, ceramics, glass, wood, and plastics in general.

Which Objects Can Be Reproduced with DIY Silicone Rubber?

You can reproduce practically any object made of any material. From a small metal ring to a large life-size statue. There are no limits, as long as you properly prepare the workspace and, above all, choose the right product!

What is the difference between Liquid Silicone Rubbers and Silicone Rubber Paste?

Liquid silicone rubber for molds is a casting silicone that is poured directly over the model to be reproduced (after placing it inside a container to prevent the silicone from flowing away). Here is a Video where you can find the complete procedure.

Being liquid, it penetrates into every corner and creates a faithful copy of the original. It is particularly suitable for 3D molds (for example, a ring or a small figurine), but it requires more preparation time (due to the container where the original will be placed and then covered with silicone rubber for molds).

Advantages:
✅ Reproduces all details (3D)
✅ Reduces the risk of air bubbles

The two-component silicone rubber paste is a soft compound, particularly easy to use and non-toxic. Like “modeling clay”, it is applied directly onto the original object that you want to reproduce.

Here is an example of how easy and quick it is to use!

Being a paste, it tends to penetrate less and is therefore particularly recommended for 2D molds (for example, a medallion or an inlay).

Advantages:
✅ Fast
✅ Completely non-toxic
✅ Extremely easy to use.

Silicone Pastes for Molds, Which Ones Should You Choose?

ResinPro has developed the IGUM line to meet all the needs of its customers.

IGUM is a two-component, non-toxic, and extremely easy-to-use paste. Being a paste, it does not run and is ideal for reproducing “2D” objects (such as coins, medallions, or decorations).

For example, if you want to reproduce a decorative detail on a vertical surface, you can simply apply this paste over it (as it does not drip) and, after just 4 minutes, have a ready-to-use mold!

How to Choose the Hardness of a Silicone?

Silicone rubbers can have different consistencies (or hardness levels), which are normally measured in “Shore” values. The higher this value, the “harder” the mold will be.

For example, a 20 Shore silicone will be harder than a 5 Shore silicone.

Normally, high Shore molds (from 30 Shore and above) have the advantage of not deforming during casting, maintaining the original shape, and are generally used for larger castings.

How to Keep a Silicone Mold in Good Condition

To keep a silicone rubber mold in good condition, it is recommended to treat it with Silicone Oil every 10–15 uses.

ResinPro Silicone Oil is a liquid that can be applied with a brush inside the mold and left to dry for a few hours (then removing any residue with a cloth).

This will renew the mold surface, significantly extending the “life” of your Silicone Mold!

It is extremely easy and affordable to use and will prevent the silicone from deteriorating, losing its shine, or, even worse, sticking to the material used to fill the mold!
