Product Name
Permabond 802 Cyanoacrylate high viscosity, fast curing, surface insensitive adhesive
Brief Description
Permabond 802 is a modified ethyl cyanoacrylate adhesive characterized by its fast curing properties, surface insensitivity, and high-temperature resistance. It is designed to form strong bonds rapidly on a wide variety of materials without the need for mixing or heat curing.
Popular Applications & Uses
- Bonding metals, ceramics, plastics, elastomers, wood, fabric, and leather.- Ideal for high-speed production lines and assembly operations.- Used in model and jewelry assembly.- Suitable for wire tacking and strain relief in electronics, including speakers, motors, and computer boards.- Employed in bonding components for mobile phones.- Can withstand brief periods of higher temperatures, making it suitable for processes like paint baking and wave soldering, provided the joint is not unduly stressed.
Industries that Commonly Use It
- General Manufacturing- LED/Electronics (for bonding components and wire tacking)- Metal Fabrication (due to strong adhesion to metals)- Plastic Fabrication (for bonding various plastics)- Automotive Service/Repair (for general bonding applications in manufacturing and repair)- Artist, Artisan (for model and jewelry assembly)- Industrial Supply (as a high-performance industrial adhesive)- Distributers & Resellers (as it is sold through distributors like Perigee Direct)
Special and Unique Features
- High temperature resistance, capable of continuous operation up to 160°C (320°F) and brief exposures to higher temperatures.- Rapid curing and fast setting, achieving handling strength in seconds.- Surface insensitive, allowing for consistent and reliable curing even on acidic or porous surfaces like wood and dechromated metals.- Ease of use, requiring no mixing or external heat cure.- 100% reactive formulation, containing no solvents.- Cures by reacting with trace amounts of moisture present on the substrate surfaces.

Comparison Note
The user's prompt and the provided URL (https://www.perigeedirect.com/products/permabond-802-cyanoacrylate-high-viscosity-fast-curing-surface-insensitive-adhesive) describe Permabond 802 as a "high viscosity" adhesive. However, Permabond's official technical data sheets and product descriptions from various distributors consistently classify Permabond 802 as a "low viscosity" modified ethyl cyanoacrylate, typically with a viscosity range of 90-110 mPa.s (cP) at 25°C. High viscosity cyanoacrylates are generally thicker and often preferred for gap filling or applications on vertical surfaces.
