Clear Gum is a translucent liquid silicone rubber in a 1:1 ratio that vulcanises at room temperature through a polyaddition reaction. + Gloves and shovel free +
Very easy to use, it allows the creation of molds and molds that are perfect and aesthetically very attractive.
Given the type of rubber catalysis, any type of material (metal, wax, plastic, wood, plaster, etc.) can be used as master or negative models.
The vulcanization time varies depending on the ambient temperature and that of the product, we recommend 23 ° C as the optimal temperature for use. At this temperature the hardening occurs after about 60 minutes, at the end of which it is possible to open the mold or extract the object.
The 8 Shore A hardness makes the molds made with this silicone rubber very soft and flexible and allows easier removal of complex objects. Moreover, in the liquid state the rubber is very fluid and can easily penetrate all the spaces of the master (or negative).
- Easy (Ratio 1: 1)
200g (100g + 100g)
500g (250g + 250g)
1Kg (500g + 500g)
The translucent color allows you to catch a glimpse of the object that is incorporated into the rubber and cut the mold in half with greater precision to easily create a bivalve mold in a short time.
What is a bivalve mold?
A bivalve mold is a mold composed of two halves which, when joined together, reproduce the complete model of all its parts of a master (object to be reproduced). With the bivalve mold technique it is possible to make molds of 3D models that would otherwise be impossible to reproduce and extract through simple molds.
Inside this silicone rubber it is possible to cast epoxy resins, polyurethane resins, liquid gypsum, etc.
Catalysis systems for polyaddition are very sensitive to pollutants such as: plasticine, tin salts (traditional rubber catalysts), salts of heavy metals, sulfur, chemical release emulsions (if necessary use natural release agents).
