Detailed description

Platinum liquid silicone rubber, cold vulcanizing through a polyaddition reaction, to be used for casting.

Key features:

  • Medium-low viscosity, able to penetrate anywhere and reproduce every detail.
  • Suitable for the construction of pit molds, i.e., single-valve, of small objects even very detailed and with strong undercuts, such as figurines, statues, bas-reliefs, candles, etc.,
  • It can also be brought into a gel phase with THIXOTROPIC AGENT GSA for brush or spatula application.
  • With some precautions, it is possible to also create two-part or inter-cavity molds, to reproduce objects of a more complex structure or larger dimensions.
  • Thanks to a medium Pot-life (60' at 25°C) and a low viscosity, this rubber allows for the total escape of trapped air.
  • Demolding can be carried out after about 15 hours at 25°C.
  • The ease of use is given by the 1:1 volume ratio, but it is necessary to remember that GLS-PRO cannot be cast directly on some materials (e.g., products containing sulfur, like plasticines, polyester-based resins, PVC, tin, and heavy metals in ionic form, amines) to avoid inhibition of the catalysis.
  • Like all silicone rubbers, this rubber is non-stick on all materials except other silicone materials in general, on which it may have a more or less tenacious adhesion. Therefore, when not using masters in such materials, the use of release agents can easily be used.
  • Finally, it is necessary to pay attention to the use of silicone rubbers on porous materials such as natural stones, plasters, gypsum, terracotta.
