When assembling close-fitting plastic, rubber, or metal components, waiting for adhesives to set slows production. Permabond 102 delivers rapid, precise bonds, ensuring components fixture in seconds without the need for mixing or heat. This low-viscosity cyanoacrylate flows into the tightest joints, achieving strong, reliable adhesion to keep assembly lines moving efficiently.
Permabond 102 is engineered for the demands of high-speed assembly, where fast, reliable bonding of close-fitting components is critical. This ethyl cyanoacrylate adhesive reacts with surface moisture to cure almost instantly when pressed into a thin film, eliminating bottlenecks associated with traditional adhesives. It is formulated to create strong, permanent bonds across a wide range of materials, including most plastics, rubbers, and metals, without the need for complex mixing or heat processes. Unlike higher viscosity cyanoacrylates, Permabond 102's low viscosity (70-90 mPa.s) ensures it effectively penetrates and bonds components with gaps up to 0.15 mm, providing precise adhesion where others might struggle to wick.
The core of Permabond 102's performance lies in its ability to bond tightly matched parts. With a maximum gap fill of 0.15 mm, it is specifically designed for close-tolerance assembly, unlike higher viscosity alternatives that might bridge these small gaps. Its rapid fixture time, typically between 5 to 15 seconds across various substrates like Buna N Rubber, PVC, and Steel, means components can be handled almost immediately, drastically improving production throughput. Once cured, it delivers high shear strength, for example, 19-23 N/mm² on steel, and often results in substrate failure on plastics like ABS and PVC, indicating a stronger bond than the material itself. The colourless appearance also ensures a clean, unobtrusive finish.
Using Permabond 102 streamlines assembly. The single-component formula requires no mixing or heat. Simply apply a sparing amount to one clean, dry, grease-free surface. Bring components together quickly and apply pressure to ensure the adhesive spreads into a thin film. Handling strength is achieved within seconds, but do not disturb until fully set. For cleanup, any surplus adhesive can be removed with Permabond CA solvent, nitromethane, or acetone. Surfaces should be degreased with a suitable solvent like acetone or isopropanol prior to application. For materials like polypropylene, polyethylene, PTFE, or silicone, pre-treating with Permabond Polyolefin Primer (POP) is necessary to achieve optimal adhesion.
In systems where certain substrates are difficult to bond or require even faster cure times, Permabond 102 integrates seamlessly. For extremely porous surfaces, or when cure speed needs to be accelerated on larger gaps or acidic surfaces, applying a Permabond C Surface Activator (CSA) or Permabond QFS 16 prior to adhesive application ensures consistent, rapid bonding. For challenging polyolefin plastics like polypropylene, polyethylene, PTFE, or silicone, using Permabond Polyolefin Primer (POP) as a first step is crucial to establish a reliable bond.
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.
