Applications

For the manufacture of negative moulds with difficult shapes and deep incisions.
Is liquid and can be poured easily. Slight shrinkage. If necessary thicken with C-comp. or dilute with Sico Fluid. For use in the food industry, it is best to place the hardened mould in water at approx. 70-80°C for a few hours and allow it to cool down in order to neutralise the silicone.

Usage

  • Always ensure a dry and grease-free surface.
  • Mix both components in a 5-10% weight ratio and brush out a first layer. 
  • This ensures a finer reproduction of all details. 
  • Then pour the mixed rubber over the object. 
  • For a rubbing mould, you can thicken (if necessary) with thickener C 0.5-1%. 
  • Potlife: approx. 90-120 min. at 20°C. 
  • Fully cured after approx. 8 hours. 
  • Minimum wall thickness 10 mm. 
  • If you are uncertain of the substrate, it is best to make a test piece or to use Trennspray.
