SILISIL Paste 4 — silicone paste (Shore A 4)
SILISIL Paste 4 is a silicone paste from the SILISIL product range — a highly viscous, stable silicone preparation for lubrication, sealing and formulation tasks in industry, electronics and medical technology.
The Shore A hardness of 4 positions the product in the range of very soft silicones (skin replication, gel molding, podiatry).
Product benefits
- 2K addition system with precisely calibrated mixing ratio
- Shrinkage-resistant and dimensionally stable even after extended periods of inactivity
- High tear and tear propagation strength
- Excellent detail reproduction, even at the microscopic level
- Long mold lifespan with proper processing
- Compatible with most common casting and molding materials
Typical applications
- Sealing surfaces: Permanently elastic sealing of mechanical connections
- Lubrication: Highly loaded bearings and sliding surfaces
- Insulation: Electrical insulation and corrosion protection
- Formulation: Rheology component in silicone compositions
Processing and mixing
- The exact mixing ratio, pot life and demolding time can be found in the technical data sheet (TDS) on this product page
- Before processing, stir both components separately and then mix thoroughly in the specified ratio
- Degassing under vacuum (30–50 mbar) eliminates air inclusions and improves surface quality
- Ideally, processing should take place at 23 °C and 40–60% relative humidity
- Contamination by sulfur, amines, tin catalysts or PVC must be avoided in platinum-crosslinked systems — they prevent curing
Storage and shelf life
- Store in unopened original packaging at 5–25 °C, in a dry place and protected from sunlight
- Shelf life from date of manufacture as stated in the TDS — typically 12–24 months
- Carefully reseal after opening
Included documentation
- Technical Data Sheet (TDS) in German, English and French
- Safety Data Sheet (SDS) according to REACH
- Batch certificate available upon request
SILISIL Paste 4 is tested and packaged by SILITECH AG in Switzerland. Our silicone specialists are always available to advise you on the appropriate Shore hardness, the choice between the different SILISIL series, or formulation development.
