Description
Permabond® 101 is an ultra-low viscosity ethyl cyanoacrylate instant adhesive designed for wicking into tight-fitting assemblies and pre-assembled parts. It penetrates micro-gaps and porous substrates, curing rapidly at room temperature to form strong bonds.
Approved to MIL-A-46050C Type II, Class 1 and CID A-A-3097 Type II, Class 1, it is used where controlled penetration and repeatable performance are required.
This grade is commonly selected for sealing, reinforcing, and bonding closely fitted components across plastics, rubber, and metals.
