The product retains effective properties in contact with automotive fluids, such as motor oil, transmission fluids, alcohol and antifreeze solutions.

NOTE: Not recommended for parts in contact with gasoline.

 

1. For best performance bond surfaces should be clean and free from grease.

2. Full performance properties will develop over 72 hours.

3. 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.

4. Excess material can be easily wiped away with non-polar solvents.

NOTE: LOCTITE® SI 598™ is not recommended for use as a cylinder head gasket or head gasket sealant.

5. For full automatic applications a volumetric dispensing system is recommended.
