Wacker Wacker® P 250 Silicone Paste
Categories: Polymer; Thermoset; Silicone

Material Notes: Product description: WACKER® SILICONE PASTE P 250 is opaque, of medium consistency and is slightly thixotropic.

Properties: It has good insulating electrical properties, as well as good adhesion to metals and ceramic materials. WACKER® SILICONE PASTE P 250 coated parts exhibit excellent water repellency, resulting in a certain degree of protection against corrosion. WACKER® SILICONE PASTE P 250 is a paste with similar properties like WACKER® SILICONE PASTE P 300 but of medium consistency with an unworked penetration of 220 – 270 1/10 mm. The low viscosity of the paste facilitates its use as an embedding compound, release agent or lubricant in some class.


  • in applications involving movement of elastomers or plastics against metals
  • lubricants for shut-off valves, control devices, joints
  • release agents for compression molding, extruder die rings
  • insulation for ignition systems (car electrics), protection against moisture, embedding of electronic components
  • installation of cable accessories
