Herschell Silicone Paste (industrially known as 500-H) is a high-performance, semi-translucent synthetic lubricant. This 100g tube is the ideal "toolbox size" for precision applications, offering a clean, non-toxic, and non-melting solution for sealing and lubricating a vast range of materials.
Technical Specifications
- Base: High-purity Silicone oil with inorganic thickeners.
- Consistency: NLGI 2 / 3 (Medium-firm paste).
- Dielectric Strength: 20 kV/mm (Excellent electrical insulator).
- Temperature Range: Serviceable from -45°C to +200°C.
- Volume: 100g Tube (Product Code: HERS0225).
- Shelf Life: 5 years from production date.
Key Features
- Material Neutral: Unlike mineral-based greases, it will not cause rubber or plastic to swell, perish, or crack. It is the "gold standard" for O-ring and seal installation.
- Superior Water Repellency: Acts as a hydrophobic barrier, making it perfect for waterproofing electrical connectors and sealing plumbing joints.
- Non-Melting & Non-Ageing: It does not have a "drop point," meaning it won't run at high temperatures. It also resists oxidation and won't dry out or crack when exposed to air or UV light.
- Electrical Insulation: Prevents high-voltage "tracking" on insulators and protects battery terminals from oxidation and the "white powder" corrosion.
- Non-Toxic & Clean: Transparent and non-staining, making it suitable for indoor use on furniture, sliding doors, and even some food-industry machinery (guides and sideplates).
Common Applications
- Automotive: Waterproofing ignition systems, protecting battery terminals, and lubricating car window channels or door weatherstripping.
- Home & Garden: Sealing water taps, lubricating swimming pool pump O-rings, and as a sealer for gas cylinder valves.
- Electrical: Protecting exterior 220V plug points, trailer indicator connectors, and electronic control units (ECUs) on 4x4 vehicles.
- Recreational: Lubricating caravan tent grooves, ski bindings (to prevent freezing), and even softening/waterproofing leather goods.
- DIY: Lubricating wood-on-wood (drawers), glass-on-wood, and plastic-to-plastic sliding surfaces.
Usage Tips
- Preparation: Surfaces should be clean and dry. Use a degreaser if removing old petroleum-based grease to ensure the silicone paste bonds correctly.
- Precision Application: Because this is a 100g tube, you can apply it directly to specific points like the ridges of an O-ring or the pins of an electrical plug.
- Thin Film: A micro-thin layer is often more effective than a thick glob. For rubber seals, draw the seal through your greased fingers to ensure even coverage.
- Appearance Restorer: It can be applied as a polish to faded black plastic trim or leather to restore a "new" look while providing a protective UV barrier.
