WEICON Black-Seal is black, high-temperature-resistant (+280 °C/+536 °F), free of solvents, strong, oil-resistant, grease-resistant, pressure-resistant, resistant to ageing and extremely elastic (breaking elongation of approx. 500%). It is suitable for bonding and sealing in applications where particularly high oil and grease resistance is required. The product can be used on gearbox, valve and casing covers, oil sumps, water pumps, gears and axles, flanges, tanks and containers, and in many other areas.
LOCTITE® SI 598 is a metallic black, 1-part, RTV (room temperature vulcanizing) oxime silicone paste sealant. It cures at room temperature on exposure to moisture in the air to form a tough, flexible, silicone rubber gasket. Its thixotropic nature allows for easy flow dispensing, while preventing the migration of liquid product once applied to the part. It has excellent resistance to motor oils and can withstand operating temperatures from -54°C to 260°C (-65°F to 500°F). It resists ageing, weathering, and thermal cycling without hardening, shrinking or cracking.
