In this tutorial series we will learn how to use clear casting polyester resin in different applications.
Here we learn how to make small parts using silicon or plastic molds.
Coasters, pendants, jewelry, cabochons, keychains etc can be made using this tutorial.
1kg polyester resin + 50ml MEKP catalyst
Mixing cups and sticks
3 pairs of nitrile gloves
Weighing / kitchen scale
Glitters and beads.
Silicon or plastic molds
Lay a sheet of plastic on a clean work bench.
Place all the required materials on the plastic sheet.
It is important that you wear nitrile gloves while handling resins. Polyester resins have a very strong smell so it is advisable to work in an open airy room. If working in an enclosed room make sure to wear mask.
Pour the required quantity of clear casting polyester resin in a disposable cup.
For a small mold such as this we are taking 150g of resin.
Make sure to appropriately weigh the resin.
For this demonstration we are using 3 pigments: red, blue and yellow, along with small beads and glitters.
Make sure that the mold is clean and free of dust.
Measure the correct quantity of MEKP catalyst to add the resin.
For small mold we will use 1.5ml of catalyst per 100g of resin.
In this demonstration we used 2.25ml of MEKP catalyst for 150g of resin.
It is very important to properly mix the catalyst in the resin.
Spend 50-60 seconds mixing the resin.
Make sure to scrap the bottom as well as the sides of the cup to ensure even mixture of resin and catalyst.
Pour small quantities of catalyzed resin in three small cups.
Add a small quantity of different pigment to each cup.
Mix until uniform color is achieved.
We are adding small quantity of pearl powder to get metallic effect in the castings.
