Description

PlatSil® FS-20 is a fast-setting, two-part, platinum-catalyzed silicone rubber. It cures at room temperature to a milky white rubber with a Shore hardness of OO66/A20. This product features a simple 1A:1B mix ratio, usable by both weight and volume.

  • Mix Ratio: 1A:1B by weight or volume
  • Shore Hardness: A20
  • Pour Time: Approximately 8 minutes
  • Demold Time: Approximately 25 minutes
  • Cured Color: Milky White
  • Mixed Viscosity: 3,800 cP
  • Specific Volume: 24.9 in³/lb
  • Specific Gravity: 1.11
  • Elongation: 626%
  • Tensile Strength: 467 psi
  • Die B Tear Strength: 148.2 pli
  • Die T Tear Strength: 52.8 pli

The fast demold time of approximately 25 minutes allows for quick turnaround of molds and parts, while the extended pour time of about 8 minutes provides ample time for mixing and pouring. Heat can be applied to further accelerate the curing process.

Cure Inhibition:

Be cautious of contamination from sulfur-based clays, amines, tin compounds, cured polyester resin, certain paints, and some silicone rubbers, as they may inhibit the surface cure of platinum-cured rubbers.
