SILISIL RTV PAD-Dura 30
SILISIL RTV PAD-Dura 30
SILISIL ·

SILISIL RTV PP-Dura 30 is a room temperature vulcanizing 2-component silicone of the PP — Pad Printing (pad printing)series (Addition (Platinum), RTV-2) — Robust pad printing silicone Shore A 32 — for demanding printing applications with printing precision.

The mixture is prepared in a 1:1 ratio by weight . Pot life at 23 °C is approximately 20 minutes, demolding is possible after approximately 2 hours, and complete curing takes 12 hours. Temperature resistant from -40 °C to +200 °C.

Key property

Robust printing pad (Shore A 32) with excellent tear resistance (>15 N/mm) — the choice for high-throughput printing presses with precise multi-color applications.

What distinguishes SILISIL RTV PP-Dura 30

Final hardness Shore A 32 — robust
Higher final hardness for mechanically stressed molds with good service life.
Tear resistance ≥15 N/mm
High tear resistance — robust against mechanical stress when demolding abrasive materials.
Elongation at break 370%
Solid elongation at break — suitable for moderate undercuts with higher form stiffness.
Fast curing in 12 hours
Rapid full networking — the mold is ready for production within one working day.
Mixing ratio 1:1 by weight
Simple 1:1 ratio — hand-mixable without a precision scale, ideal for workshops and hobbyists.
Brownish-red mixed control
Brownish-red mixing control — the mixing color clearly shows the mixing of base and catalyst.

What is SILISIL RTV PP-Dura 30 used for?

High-throughput pad printing
Industrial printing presses with high throughput — the robust final hardness extends the service life of the printing pads.
Multicolor and precision printing
Accurate edge reproduction and repeatability for multi-colored industrial marking.
Printing on hard substrates
Suitable for glass, metal and hard plastics — higher pressure force without pad deformation.
Packaging and consumer goods printing
Industrial printing of packaging, equipment and consumer products in high volumes.
Tool and component labeling
Robust marking of tools, machine parts and industrial components.
Toy and promotional item printing
Mass production of printed promotional items, toys and advertising products.

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
Vacuum degassing
For a pore-free mold, briefly vent under vacuum.
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 2 hours, and complete hardening occurs after 12 hours.

Important Notes

Avoid crosslinking inhibitors
Addition system (platinum) — sensitive to sulfur, amine, tin, and phosphorus compounds. Avoid contact with latex gloves and PVC plasticizers.
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
1 kg + 1 kg, 5 kg + 5 kg. Other container sizes available on request.
Compatibility
Compatible with polyurethane, epoxy, and polyester casting resins. For aggressive resins, apply a release agent.

Frequently asked questions about SILISIL RTV PP-Dura 30

Practical application and design questions — answered by SILITECH.

SILISIL RTV PP-Dura 30 is a 2K silicone from the PP pad printing series (Shore A 32, brownish-red). This robust pad printing silicone (Shore A 32) is suitable for demanding printing applications requiring high-precision printing and is ideal for high-throughput pad printing and related applications.

At 23 °C, the pot life is approximately 20 minutes and the demolding time approximately 2 hours. Complete curing takes 12 hours.

SILISIL RTV PP-Dura 30 is an addition (platinum) system. Addition system (platinum) — sensitive to sulfur, amine, tin, and phosphorus compounds. Avoid contact with latex gloves and PVC plasticizers.

SILISIL RTV PP-Dura 30 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 PP-Dura 30 achieves a Shore A hardness of 32 (ASTM D 2240), a tensile strength of 4.5 N/mm² (ASTM D 412), an elongation at break of approximately 370% and a tensile strength of ≥15 N/mm (ASTM D 624).
