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.
Yes, Permabond 102 is designed for bonding close-fitting plastics, rubbers, and metals. It provides rapid fixture times, allowing for quick assembly of diverse materials.
Permabond 102 is suited for close-fitting components with a maximum gap fill of 0.15 mm. For wider gaps, bond strength and cure speed will be significantly reduced.
Yes, Permabond 102 is approved to MIL-A-46050C Type II Class 2 for existing designs. This validates its reliability for specified defence applications.
It achieves handling strength in 5-15 seconds, depending on the substrates. Full strength is developed within 24 hours. Using an activator can accelerate cure on difficult surfaces.

Warning: Cyanoacrylate. Danger. Bonds skin and eyes in seconds.
Wear approved safety goggles or a face shield (EN 166). Use chemical-resistant, impervious nitrile rubber gloves (EN 374) with a minimum thickness of 0.4 mm and appropriate breakthrough time (0.5 to 8 hours depending on exposure). Wear uniforms, coveralls, or a lab coat.
Ensure adequate ventilation in the working area. For higher volume activities, or if worker comfort requires it, local mechanical exhaust ventilation should be provided. Respiratory protection with an organic vapour filter (Type A, EN14387) may be necessary if excessive airborne contamination occurs.
Store in tightly-closed, original containers in a cool, dry place between 2°C and 7°C. Allow the adhesive to reach room temperature before opening to prevent condensation, which can shorten shelf life. Dispose of contents and containers in accordance with local and national regulations. Do not discharge into drains.
Proper surface preparation is crucial for achieving optimal bond strength and preventing adhesion failure.
Surface prep: Ensure surfaces are clean, dry, and free of grease. Use a solvent such as acetone or isopropanol for degreasing. For aluminium, copper, and their alloys, light abrasion with emery cloth can remove oxide layers and improve adhesion.
Primer: Not required.
Surface prep: Surfaces must be clean, dry, and grease-free using a suitable solvent. Ensure proper ventilation.
Primer: Not required.
Surface prep: Clean, dry, and degrease surfaces. Ensure no residue remains that could inhibit bonding.
Primer: Not required.
Surface prep: Clean and degrease as with other substrates. These materials require specific surface treatment for effective bonding.
Primer: Required. Prime first with Permabond Polyolefin Primer (POP) to ensure reliable adhesion.
