Technical data sheet for WACKER® SILICONE PASTE P 250 / Version: 1.1 / Date of last alteration: 06.06.2013 1 / 2
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.
The low viscosity of the paste facilitates its use as an
embedding compound, release agent or lubricant in
some class.
Application
- 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
Storage
The 'Best use before end' date of each batch is shown
on the product label.
Storage beyond the date specified on the label does
not necessarily mean that the product is no longer
usable. In this case however, the properties required
for the intended use must be checked for quality
assurance reasons.
Safety notes
Comprehensive instructions are given in the
corresponding Material Safety Data Sheets. They are
