How to use
For best performance bond surfaces should be clean and free from grease.
Moisture curing begins immediately after the product is exposed to the atmosphere, so 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 it to heavy service loads.
Excess material can be easily wiped away with non-polar solvents.
For full automatic applications, a volumetric dispensing system is recommended.
