SILISIL RTV PP-Ultra 50
SILISIL ·

SILISIL RTV PP-Ultra 50 is a room temperature vulcanizing 2-component silicone of the PP — Pad Printing (pad printing)series (Addition (Platinum), RTV-2) — High-strength pad printing silicone Shore A 50 — for maximum printing precision and detail resolution.

The mixture is prepared in a 1:1 ratio by weight . Pot life at 23 °C is approximately 15 minutes, demolding is possible after approximately 3 hours, and complete curing takes 12 hours. Temperature resistant from -40 °C to +200 °C.

Key feature

Highest hardness in the pad printing range (Shore A 50) — Detail reproduction down to 2 microns, dimensional change only −0.05%, high voltage resistance >16.2 kV/mm.

What makes SILISIL RTV PP-Ultra 50 stand out

Final hardness Shore A 50 — highest printing precision
Highest final hardness in the pad printing range — most precise printing with minimal pad deformation.
Detail reproduction down to 2 microns
Microscopic detail reproduction for highest reproduction precision — the finest writing and structures are captured.
Dimensional change only −0.05%
Virtually no shrinkage — the shape remains exactly dimensionally accurate until the first impression.
Tensile strength 12 N/mm²
Tensile strength 12 N/mm² — industry standard for high-quality molds.
High voltage resistant >16.2 kV/mm
High electrical insulation even under high voltage — suitable for electrical engineering and insulator applications.
Mixing ratio 1:1 by weight
Simple 1:1 ratio — mixable by hand without precision scales, ideal for workshops and hobbyists.

What is SILISIL RTV PP-Ultra 50 used for?

Microprinting with the highest resolution
2-micron detail reproduction for microelectronic components, sensors and semiconductor marking.
Industrial high-precision printing
Minimal dimensional change (−0.05%) for multi-color printing systems with high repeatability.
Printing on very hard substrates
Glass, hard metal, ceramic — the high final hardness allows ink to transfer precisely even onto resistant surfaces.
Printing with high pressure
Pad printing under higher mechanical stress — shape stability is maintained.
High-voltage insulated applications
Pressure applications in high-voltage environments — dielectric strength >16.2 kV/mm.
Heat dissipation in sensor applications
Thermal conductivity 0.12 W/mK — moderate heat dissipation in temperature-critical printing processes.

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

Frequently asked questions about SILISIL RTV PP-Ultra 50

Practical application and design questions — answered by SILITECH.

SILISIL RTV PP-Ultra 50 is a 2K silicone from the PP pad printing series (Shore A 50, grey). This high-strength pad printing silicone (Shore A 50) offers maximum printing precision and detail resolution, making it suitable for high-resolution micro-printing and related applications.

At 23 °C, the pot life is approximately 15 minutes and the demolding time approximately 3 hours. Complete curing takes 12 hours.

SILISIL RTV PP-Ultra 50 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-Ultra 50 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-Ultra 50 achieves a Shore A hardness of 50 (ASTM D 2240), a tensile strength of 4.0 N/mm² (ASTM D 412), an elongation at break of approximately 320 % and a tensile strength of 12 N/mm (ASTM D 624).
