What distinguishes SILISIL RTV PP-Flex 12

Very soft (Shore A 12) for sensitive substrates
Very soft tampon (Shore A 12) — gentle on sensitive substrates such as glass, paint and coatings.
Very high elongation at break 550%
Very high elasticity — removes aggressive undercuts without tearing.
Excellent ink transfer
Excellent color release — clean ink transfer from the printing plate to the workpiece.
Low viscosity 3,500 mPa·s
Low mixing viscosity — flows into the finest structures without air inclusions, vacuum venting optional.
Mixing ratio 1:1 by weight
Simple 1:1 ratio — mixable by hand without precision scales, ideal for workshops and hobbyists.
Tear resistance 8.6 N/mm
Tear resistance for moderate loads — suitable for small series and detailed work.

What is SILISIL RTV PP-Flex 12 used for?

Pad printing on sensitive surfaces
Printing on glass, lacquered metal, ceramic glaze and coated plastics without damaging the surface.
High-resolution detail printing
Tiny fonts, logos and symbols with the finest detail reproduction — promotional items and consumer goods.
Printing on curved components
Soft tampons conform to complex geometries — bottles, cups, domes and round cases.
Jewelry and watch marking
Precise printing of small, high-quality components with minimal mechanical pressure.
Optical and electronic components
Gentle printing of lenses, displays, touch panels and LED housings.
Medical devices and packaging
Ink transfer to syringes, tablet blisters, inhaler components — gentle and precise.

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 90 minutes, with complete hardening after 24 hours.
