WACKER® SILICONE PASTE P 300 is opaque, of medium to soft consistency and slightly thixotropic.

It has good electrical properties, i.e. insulating properties, relative permittivity and electric strength, as well as good adhesion to metals and ceramic materials. WACKER® SILICONE PASTE P 300 coated parts exhibit excellent water repellency, resulting in a certain degree of protection against corrosion.

WACKER® SILICONE PASTE P 300 is a paste with similar properties like WACKER® SILICONE PASTE P 250 but of softer consistency with an unworked penetration of 290 - 330 ¹/¹º mm.

The low viscosity of the paste facilitates its use as an embedding compound, release agent or lubricant in some class.
