Polyaddition Silicone Rubber GLS-PRO

GLS-PRO is a liquid rubber, which vulcanizes cold through a polyaddition reaction, used for casting. It is the simplest alternative to the GLS-50, with medium viscosity and it is able to reproduce every little detail. It is suitable for specifically constructing well-shaped molds of small and medium objects with strong under-square, such as figurines, bas-reliefs, candles, etc., but with GSA TIXOTROPIZING AGENT it can also be made into gel and applied with a brush or a spatula. With a few tricks you can even make bivalve or cavity molds, to reproduce objects with a more complex or larger structure. If you should find it useful, you can require the Silicone Mold Making brochure.

This type of rubber has an average pot-life (60 'at 25°C) and a low viscosity, which allows a complete escape of the air absorbed within. You can remove it from the mold after about 15 hours at 25°C. What you need to remember is; to prevent the impediment of catalysis, the GLS-PRO cannot be cast directly on some materials.
