Using it
Surfaces should be clean and grease-free. Mate the parts within a few minutes of dispensing.
Tack-free time is 25 minutes or less at 25 °C and 50 ± 5% RH. Full performance properties develop over 72 hours, and the cured values on the data sheet are measured after 7 days at 25 °C and 50% RH.
Excess wipes off with non-polar solvents. Suits volumetric dispensing for full-automatic use.
Storage and handling
Store unopened in a dry location, optimally between 8 °C and 21 °C. Storage below 8 °C or above 28 °C can adversely affect the properties of the product.
Limits and safety
Not recommended for parts in contact with gasoline, for pure oxygen or oxygen-rich systems, as a sealant for chlorine or other strong oxidising materials, or as a cylinder head gasket or head gasket sealant. Read the safety data sheet before use.
