Water-repellent silicone paste as lubricant, assembly aid and release agent
Wacker Silicone Paste P is a translucent, petroleum-jelly-like and relatively stiff silicone paste that does not cure. The paste is water-repellent, electrically insulating and has good surface slip. You use it as a lubricant and assembly aid for elastomers, especially O-rings, and as a heat-resistant release agent. Its pasty consistency changes little with temperature fluctuations.
Key benefits
- Water-repellent: coated parts repel water well, which gives a degree of protection against corrosion.
- Stays pasty: the paste does not cure and its consistency changes little with temperature.
- Easy to work: the paste softens when kneaded or subjected to other mechanical stress.
- No dripping: unlike oil, the paste stays where you apply it.
- Electrically insulating: with high dielectric strength.
- Good adhesion: to metals, glass and ceramics.
Typical applications
- ✓ Assembly aid and lubricant for elastomers, especially O-rings
- ✓ Heat-resistant release agent for extruder die rings
- ✓ Release agent on slightly porous mould surfaces when demoulding rubber and plastic mouldings and casting resin parts
- ✓ Thin film on the sealing bars of heat sealers for packaging film, to prevent sticking
Processing
- Grease larger parts with the neat paste, by hand or with a brush.
- Put small parts in large quantities into a plastic bag with a little paste. Knead the bag until the paste is spread over all surfaces.
- As a release agent, apply a thin film to the mould surface or the sealing bars.
Points to note
- ✓ Silicone pastes have a slight swelling effect on most organic elastomers. For materials that are sensitive to swelling, Wacker recommends POWERSIL® PASTE AP, which is specially designed to cause little swelling of adjacent elastomers.
- ✓ Keep the paste tightly closed in its original packaging.
