Cyanoacrylate adhesives offer ultra-fast cure
Generic cyanoacrylates have earned the reputation of 'instant' adhesives from their ability to be used immediately with little preparation and to cure very quickly. Threebond claims that its TB7700 Gold Series takes that a stage further with ultra-fast curing (from just two seconds), very high initial bond strength and enhanced substrate applicability, even encompassing porous and hard-to-bond materials such as PBT, PCM and PPS. The company says that industrial users will find Gold Standard TB7700 a significant advance over conventional cyanoacrylates.
Threebond TB7700 is based primarily around ethyl-x-cyanoacrylate technology re-formulated to bond more quickly to an extensive range of common materials and provide tensile shear strengths frequently in excess of the substrate itself. Suitable substrates include many metals, polyethylenes, polycarbonate, nylons, rubbers, papers, woods, ceramics, etc.
The Gold Label Series was created by Threebond in response to the needs of industrial processes to bond parts quickly, dealing with varying permeability and even in place of traditional jigging fixtures to hold assemblies while epoxies or acrylic adhesives achieve full cure and maximum strength.
Test results with clean but untreated surfaces in a relative humidity of 50 per cent at 25degC have shown remarkably aggressive performances. Low levels of surface moisture are, of course, required to trigger a chemical cure in cyanoacrylates, and this is one reason why they are such a relatively tolerant family of adhesives.
Threebond Gold Series is available in 20g, 50g and 500g bottles to suit production/installation requirements.
