How to Use Clear Polyester Casting Resin

Clear polyester casting resin is a versatile material that can be used to create a variety of objects, from jewelry and home décor to sculptures and furniture. It is a two-part resin system, consisting of a resin and a hardener, that when mixed together, will cure into a hard, durable plastic.

To use clear polyester casting resin, you will need the following materials:

* Clear polyester casting resin

* Hardener

* Mixing container

* Stirring stick

* Mold

* Gloves

* Safety glasses

* Respirator

Step 1: Prepare your mold

The first step is to prepare your mold. If you are using a silicone mold, you can skip this step. However, if you are using a hard mold, such as a plastic or metal mold, you will need to coat the mold with a mold release agent. This will help to prevent the resin from sticking to the mold and will make it easier to remove the finished product.

Step 2: Mix the resin and hardener

Once your mold is prepared, you can mix the resin and hardener. The resin and hardener should be mixed in a 1:1 ratio by volume. For example, if you are using 100 ml of resin, you will need to add 100 ml of hardener.

Be sure to mix the resin and hardener thoroughly. If the resin and hardener are not mixed thoroughly, the finished product will be weak and brittle.

Step 3: Pour the resin into the mold

Once the resin and hardener are mixed, you can pour the resin into the mold. Be sure to pour the resin slowly and carefully to avoid creating bubbles.

If you do create bubbles, you can use a heat gun to remove them. Simply hold the heat gun about 6 inches away from the surface of the resin and move it back and forth until the bubbles disappear.

Step 4: Cure the resin

The resin will typically cure in about 24 hours at room temperature. However, you can speed up the curing process by placing the mold in a warm oven. The resin will cure in about 1 hour at 150 degrees Fahrenheit.

Step 5: Remove the finished product from the mold

Once the resin is cured, you can remove the finished product from the mold. If you are using a silicone mold, you can simply peel the mold away from the product. If you are using a hard mold, you may need to use a mold release agent to help remove the product.
