WACKER® SILICONE PASTE P is a translucent, vaseline-like, relatively stiff, waterrepellent paste.

WACKER® SILICONE PASTE P coated parts exhibit excellent water repellency, resulting in a certain degree of protection against corrosion.

 WACKER® SILICONE PASTE P becomes softer when subjected to shear stress or other mechanical stress such as kneading, which in many instances makes processing easier.

The pasty consistency is little affeted by changes in temperature. The components of WACKER® SILICONE PASTE P are on the positive lists of the following Regulations for food contact: Regulation (EU) No. 10/2011, Recommendation XV. Silicones of the BfR (Federal Institute for Risk Assessment) and the FDA Code of Federal Regulations Title 21 § 175.3570 Lucbricants with Incidental Food Contact.


  • non-curing, with retention of pasty consistency
  • water resistant, water repellent
  • electrically insulating
  • good surface slip
  • high dielectric strength
  • Good adhesion to metals, glass and ceramics
  • Food-contact

Specific features of WACKER® SILICONE PASTE P

  • Lubricant

Assembly aid and lubricant for elastomers, especially O-rings.

WACKER® SILICONE PASTE P is easy to apply. There is no dripping as when using oil. Larger parts are greased with the pure paste by hand or with a brush; smaller parts in large quantities are put into a plastic bag with some paste and kneaded until the paste has been distributed over their surfaces. Silicon pastes have a slight swelling effect on most organic elastomers. For lubricating purposes and as assembly aid for materials with critical swelling characteristics we would, however, recommend using silicone product POWERSIL® PASTE AP, which is especially designed for causing low swelling of bordering elastomers.


Heat-resistance release agent for :

  • extruder die rings
  • slightly porous surfaces of moulds for demoulding rubber and plastics mouldings and cast resin parts
  • heat-sealing instruments such as used for Packaging Film, where a thin film of WACKER® SILICONE PASTE P applied to the welding bars prevents sticking
