What makes SILISIL RTV PC-Putty 30 Fast CATALYST stand out

Potting time only 2 minutes
Very short processing time — suitable for high-throughput production with short mold cycles.
Setting time 15 minutes — fastest PC-PuTTY variant
Fastest setting time of the variant — ideal for urgent reproductions and workshop demos.
Bright red — visible mixing control with BASE
Bright red mixing control — color change makes mixing with BASE visually verifiable.
Polycondensation — resistant to inhibitors
The condensation system does not react to sulfur, amine and PVC inhibitors — certainly not even to problematic originals.
Mixing ratio 1:1 with BASE
Simple 1:1 ratio with BASE component — no scale needed, volume mixing possible.
Dimensional change <0.57%
Minimal dimensional change — precise reproduction even after several days of storage.

What is SILISIL RTV PC-Putty 30 Fast CATALYST used for?

Urgent direct impressions
When the mold needs to be ready for use within 15 minutes — workshop, demo, repair.
Top-quality replicas
Tool and coin detail impressions on site — Fast version, no setup, no vacuum.
Jewelry workshop at a fast pace
Directly mold the goldsmith's model; a short pot life prevents deformation of the original.
On-site repairs on the model
Quickly repair cracks and damage — finish the mold before the end of the break.
Demo and trade show applications
Live performances with a complete form cycle within the audience's attention span.
High-throughput production
Multiple mold cycles per hour — suitable for small production runs with short delivery times.

processing

1
Prepare the original
Clean, dry and dust-free surface at 23 °C — cooler environments significantly extend pot life and curing time.
2
Mixing components
Stir the base and catalyst thoroughly before use. Weigh out 1:1 by weight. Mix thoroughly, including the sides and bottom of the container.
3
Use without venting
Polycondensation does not require a vacuum — pour or apply directly.
4
Process
Pour in a thin stream from a height of approximately 30 cm — minimizing air bubbles. For modeling clay, press directly onto the model.
5
Vulcanizing and demolding
At 23 °C, demolding is possible after approximately 15 minutes; complete hardening occurs after 24 hours.
