Loctite SI 598 RTV Silicone Gasket Maker Black 80ml Tube

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 it's applied to the part. It has excellent resistance to motor oils and can withstand operating temperatures from -54 to +260°C. It resists aging, weathering, and thermal cycling without hardening, shrinking, or cracking.

Features:

  • Excellent motor oil resistance
  • Forms tough, flexible, silicone rubber gasket
  • Typical applications include oil pans, transmission pans, valve covers, valves and guides, timing gear covers, and differential covers
  • Resists aging, weathering, and thermal cycling
  • It does not harden, shrink, or crack
