Generic cyanoacrylates have earned the reputation of ‘instant' adhesives from their ability to bond quickly with little joint preparation. ThreeBond's TB7700 Gold Series is formulated to take this capability a stage further, offering ultra-fast curing (as low as 2s), high initial bond strength and enhanced substrate applicability, even encompassing porous or hard to -bond materials such as PBT, PCM or PPS. The company expected all types of industrial user will find the product a significant advance over conventional materials.

ThreeBond TB7700 is based around ethyl-x-cyanoacrylate technology re-formulated to bond remarkably quickly to an extensive range of common materials, while providing tensile shear strengths frequently exceeding the substrate itself. Suitable substrates include metals, polyethylene, polycarbonate, nylon, rubber, paper, wood and ceramic.

ThreeBond stated it created the Gold Label Series in response to the need for industrial processes capable of bonding parts quickly while dealing with varying permeability. It can even be used to replace traditional fixtures to hold assemblies while epoxies or acrylic adhesives achieve full cure and maximum strength.

The company states test results with clean, untreated surfaces in relative humidity of 50 per cent at 25°C have shown remarkably aggressive performances. Low levels of surface moisture are required to trigger a chemical cure in cyanoacrylate, one reason why they are a relatively tolerant family of adhesives.
