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 Advantages
- 2K addition system with precisely matched mixing ratio
- Low shrinkage and dimensionally stable even after prolonged storage
- High tear and tear propagation resistance
- Excellent detail reproduction even at a microscopic level
- Long mold life with proper processing
- Compatible with 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 modifier in silicone compositions
Processing and Mixing
- For the exact mixing ratio, pot life, and demolding time, please refer to the technical data sheet (TDS) on this product page
- Before processing, stir both components individually and then mix thoroughly in the specified ratio
- Degassing under vacuum (30–50 mbar) eliminates air inclusions and improves surface quality
- Processing ideally 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 container at 5–25 °C, dry and protected from direct sunlight
- Shelf life from the manufacturing date specified in the TDS — typically 12–24 months
- After opening, reseal carefully
Included Documentation
- Technical Data Sheet (TDS) in German, English, and French
- Safety Data Sheet (SDS) according to REACH
- Batch certificate on 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.
