Narrow gap curing type
In-page Navigation
What is the PLENSETTM narrow gap curing type?
Applying the no particle type curing system enables bonding even to narrow gaps and minute amounts without curing failure due to separation.
Curing is complete in 30 to 60 minutes when heated to 80 to 120degC.
The cured material generates minimal outgas, making it applicable to precision machinery that requires low outgassing, such as HDD parts. (Model: AE-780)
Superior pot life at room temperature results in excellent stability in the dispensing process.
