- Cheap filler
- Easy to measure out
Acrylic resin with glass fibres and glas fibre cloth is a strong cheap way to build a support shell for your flexible silicone mold.
Please note that glassfibre cannot be stretched. If you want to add these fibres to silicone it will lose its elasticity.
Glass fiber consists of glass. This means that microscopic glass splinters are formed during the build of the composite and/ or later processing (drilling, cutting, sanding etc) of the endproduct. These are irritating to the skin and eyes and are especially harmful to the lungs when inhaled. We therefore recommend using a dust mask and sturdy gloves.
If the fibres has already been treated with a resin, we also recommend using a mask with a gas filter to prevent fumes from escaping. It is aways important to work in a well ventilated area.
