LOCTITE SI 5900

Main features

  • At Least 100-Second Blow-Out Resistance
  • At Most 0.2 mm ISO 7390 Flow
  • At Least 400% Cured Elongation

Product Description

LOCTITE SI 5900 is a one-component black oxime RTV silicone gasketing compound for stamped sheet-metal covers, including timing covers and oil sumps. The thixotropic paste has a typical specific gravity of 1.3 to 1.37 at 25 deg C. It records at least 100 seconds of blow-out resistance on a 4 mm flange with a 1.5 mm gap at 0.014 MPa and at most 0.2 mm flow after 2 minutes at 25 deg C by ISO 7390. Typical tack-free time is 7 to 24 minutes at 25 deg C and 50+/-5% RH. After one week under those conditions, cured elongation is at least 400%.

Key features

  • Flow Control: ISO 7390 flow is at most 0.2 mm after 2 minutes at 25 deg C.
  • Blow-Out Test Performance: Records at least 100 seconds on a 4 mm flange with a 1.5 mm gap at 0.014 MPa.
  • Cured Flexibility: Elongation is at least 400% by ISO 37 after one week at 25 deg C and 50+/-5% RH.

Applications

Stamped covers; timing covers; oil sumps; similar gasketing applications.
