LOCTITE® SI 5900™

Excellent resistance to automotive engine oils

• Cure - Room temperature vulcanizing (RTV)
• Application - Sealing

• Typical applications include stamped sheet metal covers (timing covers and oil sumps) where good oil resistance and the ability to withstand high joint-movement is required.
• It withstands on line, low pressure tests carried out before product begins to cure.
• The thixotropic nature of the product reduces the migration of liquid product after application to the substrate.
• This has an excellent adhesion profile to an outstanding wide variety of plastic substrates, as well as glass, ceramics and metals.

• For best performance bond surfaces should be clean and free from grease.
• Moisture curing begins immediately after the product is exposed to the atmosphere, therefore parts to be assembled should be mated within a few minutes after the product is dispensed.
• The bond should be allowed to cure (e.g. seven days), before subjecting to heavy service loads.
• Excess material can be easily wiped away with non-polar solvents.

This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected as a sealant for chlorine or other strong oxidizing materials.
