What distinguishes SILISIL RTV PC-Putty 30 Slow CATALYST

Pot time 90 minutes — relaxed processing
Very short processing time — suitable for high-throughput production with short mold cycles.
Polycondensation — resistant to inhibitors
The condensation system does not react to sulfur, amine and PVC inhibitors — certainly not even to problematic originals.
Light yellow — visible mixing control with BASE
Light yellow mixing control — color change indicates complete mixing with BASE component.
Elongation at break 200% for Shore A 30
Solid elongation at break — suitable for moderate undercuts with higher form stiffness.
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 Slow CATALYST used for?

Complex multi-part molds
Building up multiple layers and partial shapes on top of each other — the long pot life allows for clean handwork.
Large-area direct impressions
Molding reliefs, sculptures and large models — no rush, clean result.
Detailed corrections to the model
90 minutes for precise modeling and correction work on the still malleable putty.
Training and teaching applications
Suitable for workshops — enough time for explanations, demonstrations and corrections during processing.
Jewelry and artist studios
Direct impression taking with time for several detail stages and modeling work.
First-time users and hobbyists
Ideal for beginners — more time to practice, no stress from too short a potting time.

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 18–22 hours, with complete hardening after 24 hours.

Frequently asked questions about SILISIL RTV PC-Putty 30 Slow CATALYST

Practical application and design questions — answered by SILITECH.

SILISIL RTV PC-Putty 30 Slow CATALYST is a 2K silicone from the PC polycondensation series (Shore A 30, light yellow). It is a slow catalyst for PC-Putty 30 BASE, with a pot life of 90 minutes, suitable for complex assemblies, multi-part molds, and related applications.

At 23 °C, the pot life is approximately 90 minutes and the demolding time approximately 18–22 hours. Complete curing occurs after 24 hours.

SILISIL RTV PC-Putty 30 Slow CATALYST is a polycondensation (tin catalyst), slow-action system. Polycondensation system (tin catalyst) — no susceptibility to poisoning from sulfur, amines, or PVC. Vacuum venting is not mandatory.

SILISIL RTV PC-Putty 30 Slow CATALYST is mixed in a 1:1 ratio by weight (base to catalyst). Homogenize both components separately before mixing, then thoroughly incorporate them – including the container walls and bottom.

SILISIL RTV PC-Putty 30 Slow CATALYST achieves a Shore A hardness of 30 (ASTM D 2240), a tensile strength of 0.9 N/mm² (ASTM D 412), an elongation at break of approximately 200% and a tensile strength of 3.3 N/mm (ASTM D 624).
