SILISIL · SKU 90-0906.PC.ML060

SILISIL RTV PC-Putty 30 Fast CATALYST is a room temperature vulcanizing 2-component silicone of the PC — Polycondensation- series (Polycondensation (tin catalyst), Fast, RTV-2) — Fast catalyst for PC-Putty 30 BASE — Pot life 2 min, setting 15 min.

The mixture is prepared in a 1:1 ratio by weight . Pot life at 23 °C is approximately 2 minutes, demolding after approximately 15 minutes, and complete curing after 24 hours. Temperature resistant from -40 °C to +200 °C.

Key property

Rapid setting catalyst for SILISIL PC-Putty 30 BASE — when combined, it forms a 1:1 putty with a pot life of 2 minutes and ready for shaping after 15 minutes. Bright red tinted for easy mixing control.

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

Pot life 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
Mix components
Stir base and catalyst thoroughly before use. Weigh out 1:1 by weight. Mix in thoroughly, including container walls and bottom.
3
Use without venting
Polycondensation does not require a vacuum — pour or apply directly.
4
Processing
Pour in a thin stream from a height of approximately 30 cm — minimizing air bubbles. For modeling clay, press directly onto the model.
5
Vulcanize and demold
At 23 °C, demolding is possible after approximately 15 minutes; complete hardening occurs after 24 hours.

Important Notes

Polycondensation — robust against inhibitors
Polycondensation system (tin catalyst) — no susceptibility to poisoning from sulfur, amines, or PVC. Vacuum venting is not strictly necessary.
Storage and Shelf Life
Shelf life of at least 12 months in unopened original container when stored in a dry, cool place (10–25 °C). Consult the SDS before opening.
Available containers
500 g, 1 kg, 5 kg. Other package sizes available on request.
Compatibility
Compatible with polyurethane, epoxy, and polyester casting resins. For aggressive resins, apply a release agent.
