Premium Antistatic Silicone Casting Rubber for Professional Applications
SilSo Print 21004 is a pourable, addition-cure two-component silicone rubber that cures at room temperature. The product has been specially developed for the production of antistatic silicone printing pads for pad printing applications. The cured rubber combines excellent physical properties with antistatic properties – a reliable choice for demanding printing applications.
Key Benefits
- Antistatic properties: Specifically formulated for pad printing pads that are sensitive to electrostatic discharge.
- Minimal shrinkage (<0.1%): Extremely accurate reproduction of fine details without dimensional deviation.
- Room temperature curing: No oven required – tack-free after 8–12 hours, fully cured after 12 hours at 23°C.
- Excellent tear strength (3.5 N/mm): Durable pads with a long service life in production environments.
- High elongation at break (350%): Flexible and resilient rubber that accurately follows complex shapes.
- Easy processing (1:1 by weight): Can be mixed evenly by hand or mechanically at low speed.
Typical Applications
- Production of antistatic silicone printing pads for pad printing
- Moulds for precision casting in the electronics industry
- Reproduction of fine surface textures in prototyping
- Casting of parts in the automotive sector
- Moulds for decorative applications in the art and design sector
- Production of flexible moulds for ceramics and plaster
Technical Features
Mix ratio 1:1 by weight. Part A (translucent) contains the platinum catalyst; Part B (blue) is the crosslinker.
