Wacker POWERSIL-Paste AP High-Voltage Insulating Silicone Grease (P4 Upgrade)
Ensure the peak performance and safety of your high-voltage electrical systems with Wacker POWERSIL-Paste AP. This professional-grade insulating silicone grease is specifically engineered as an advanced upgrade to the P4 model, offering superior dielectric properties and mechanical stability. Designed primarily for the demanding requirements of X-ray machines and high-voltage cable accessories, this whitish paste provides a robust barrier against electrical breakdown while maintaining its consistency under extreme thermal stress.
As an authentic German-engineered solution, POWERSIL-Paste AP is the industry standard for technicians requiring a reliable, non-melting lubricant that excels in moisture displacement and surface protection. Whether you are sealing high-voltage connectors or maintaining medical imaging equipment, this paste delivers the precision and longevity required for critical infrastructure.
Key Benefits
- Superior Dielectric Strength: With a dielectric strength of 20 kV/mm, this paste provides exceptional insulation, preventing arcing and electrical leakage in high-tension environments.
- Extreme Temperature Resilience: Engineered to remain functional across a vast thermal spectrum, featuring a solidifying point of -45°C and an operating range that extends up to 200°C.
- High-Efficiency Moisture Barrier: Being completely insoluble in water, it creates a waterproof seal that protects sensitive components from humidity, oxidation, and environmental contaminants.
- Low Volatility and Bleeding: Optimized for longevity, the formula exhibits minimal oil separation (max 4.0%) and low evaporation (max 5.0%) even after 30 hours at 200°C, ensuring the grease stays exactly where it is applied.
- Enhanced P4 Formula: This upgraded version offers improved penetration characteristics, allowing for easier application and better coverage on complex surface geometries.

How to Use
- Preparation: Ensure all application surfaces are clean, dry, and free from old grease, dust, or carbon deposits.
- Application: Apply the paste using a clean spatula, brush, or lint-free cloth.
- Coating: Spread a uniform layer over the target area, such as X-ray tube heads, high-voltage cable terminations, or electrical bushings.
- Assembly: Join the components immediately after application to ensure the grease fills all microscopic voids and excludes air, which is vital for preventing corona discharge.
Care & Safety
- Storage: Store in the original tightly sealed container in a cool, dry area.
- Light Sensitivity: Keep away from direct sunlight and high-intensity UV sources to maintain chemical stability.
- Handling: While chemically stable, avoid prolonged skin contact and eye contact. Wash hands thoroughly after use.
- Contamination: Do not mix with other types of grease or lubricants, as this may alter the dielectric properties.
