For high-speed production lines and fast fixturing of close-fitting components, Permabond 102 provides rapid bonding of plastics, rubber, and metals. This low-viscosity ethyl cyanoacrylate polymerises quickly when pressed into a thin film between components, utilising surface moisture to initiate the cure without mixing or heat.
Permabond 102 operates as a single-component adhesive that must be applied sparingly to a single surface. Bringing the parts together under pressure spreads the liquid to its required thin film, developing handling strength on plastics like PVC and ABS in 7 to 10 seconds, and on Buna N Rubber in 5 to 10 seconds. On non-porous rigid substrates, the cured adhesive achieves high shear strength, causing substrate failure on ABS, PVC, and polycarbonate rather than bond failure.
Suitable for bonding close-fitting industrial plastics, rubbers, and metals. Specific compatible substrates include:
Do not use Permabond 102 in contact with strong oxidising materials or polar solvents, though the cured joint will withstand a brief solvent wash. Acidic surfaces or gaps larger than 0.15 mm will reduce the cure speed. Avoid bonding difficult plastics such as polypropylene, polyethylene, PTFE, or silicone without pre-treating the surfaces with Permabond Polyolefin Primer (POP).
Surfaces must be clean, dry, and free of grease before application. Clean and degrease surfaces using acetone or isopropanol. For aluminium, copper, and copper alloys, lightly abrade the surface with emery cloth to remove the oxide layer before bonding.
Apply the adhesive sparingly to one surface and assemble the parts quickly to ensure correct alignment. Apply sufficient pressure to spread the adhesive into a thin film. Do not disturb or re-align the joint during the first few seconds of assembly. Excess uncured adhesive can be cleaned using Permabond CA solvent, nitromethane, or acetone.
Store the container between 2°C and 7°C. To prevent moisture condensation inside the bottle—which cures the adhesive and reduces shelf life—always allow the cold bottle to reach room temperature before opening.
How fast does Permabond 102 fixture?
Typical fixture time is about 5 to 15 seconds depending on the substrate.
What gap can it fill?
It is designed for close-fitting parts with gaps up to about 0.15mm.
How long to full cure?
Allow about 24 hours for full strength.
Can it bond polypropylene or polyethylene?
Yes, but those plastics require Permabond Polyolefin Primer first.
