WACKER® Silicone Paste P 250

WACKER® Silicone Paste P 250 is an opaque paste with a medium consistency and slight thixotropic properties. It possesses good electrical properties, including insulation, relative permittivity, and electric strength. Additionally, it exhibits strong adhesion to metals and ceramic materials. When applied as a coating, WACKER® Silicone Paste P 250 provides excellent water repellency, offering a certain level of protection against corrosion. The paste's low viscosity makes it easy to use as an embedding compound, release agent, or lubricant in various applications.
