Can silicone molds for epoxy resin be reused?

Resin can be used to create a wide variety of decorative pieces, such as jewelry, key chains, magnets, coasters, pictures, figurines and much more. To shape the resin, you need molds that are adapted to the shape and size you want.


Epoxy resin molds can be made of different materials, such as plastic, metal, wood or silicone. However, one of the most popular and recommended materials for making resin molds is silicone. Silicone is a resistant and flexible material, which has several advantages when working with it.

Some of these advantages are:

1.Silicone is non-stick, which makes it easy to demold the resin part without leaving a trace or damaging the mold or part.

2.Silicone is flexible, which makes it possible to make molds of complex and detailed shapes, and also to demold parts with relief or curves without problems.

3.Silicone is resistant, which makes molds last longer and better withstand the heat and pressure of the resin.

4.Silicone is transparent or translucent, allowing you to see inside the mold and better control the pouring and curing process of the resin.

But one of the main advantages of silicone molds is that they are reusable. This means that you can make series of the same or different pieces, without having to buy or make new molds each time. This saves money and materials, as well as being more sustainable and environmentally friendly.

In order to reuse silicone molds for epoxy resin, it is necessary to follow some tips and precautions that we explain below:

1.Use a release agent suitable for your mold. The release agent is a product that is applied on the mold before pouring the resin, to facilitate the removal of the part once the resin has cured. There are different types of release agents, such as waxes, oils, aerosols or liquids, which should be chosen according to the mold material and the resin to be used. It is important to follow the manufacturer's instructions and apply the release agent evenly and without excess, to avoid affecting the finish of the part.

2.Clean the mold after each use. Once you have demolded the resin part, you should clean the mold to remove any remaining resin or release agent.

3.Store the mold in a suitable place. After cleaning the mold, you should store the mold in a safe, clean and dry place. Avoid direct exposure to direct sunlight, extreme heat or cold, as these can affect the shape and quality of the mold. Also avoid contact with dust, moisture or insects, which can soil or damage the mold. You can wrap the mold in aluminum foil or plastic wrap, or store it in an airtight box or bag.

By following these tips, you will be able to reuse the molds and obtain art pieces easily and safely. We hope you liked this article and that you are encouraged to experiment.
