S is for Super Glue

What is Super Glue? Known as Super Glue, Instant Adhesives, Instant Glue, CA or more scientifically as C5H5NO2, Cyanoacrylate is the technical term known by most adhesive experts and it’s been around since the early 1950s. Invented, by accident, by Dr Harry Cooper who was trying to make clear plastic gun sights for Allied soldiers in WWII. The initial product was deemed to be “too sticky” but nine years later he found the potential of a product that would quickly bond a variety of substrates with only a tiny bit of moisture present. And, as its founding name suggests, just a one square inch bond of this product will hold around one tonne. Super indeed.

What are the common uses of Super Glue?

Super Glues will bond a wide range of substrates like metals, plastics, wood, glass, porous surfaces and maybe accidentally, human skin. It is a key industrial product used in automotive sub-assemblies, aerospace components, appliance part assembly, electronics, construction, and consumer products. A household staple for DIY quick fixes or hobbyists.

How does Super Glue work?

Cyanoacrylate adhesive technology is composed of an acrylic resin or monomer that evolves to a plastic state after curing. Unlike some adhesives that cure by evaporation, cyanoacrylates instantly cure in the presence of moisture which reacts instantly on exposure to air, even with a small amount of relative humidity. It only bonds the surface where moisture is present, the reaction generates heat that forms a tough resilient bond instantly at ambient temperatures.

What types of Super Glue are there?

But not all cyanoacrylates are equal. In the UK, Bondloc formulates 3 main systems – Ethyl, Methyl and Alkoxy grades which cater for most applications. Each grade has unique characteristics; varying viscosities, ultra-fast or slow set times, high-temperature resistance, rubber toughened, non-blooming and low odour or gelled formulations for vertical or overhead bonding applications.

To complement the Bondloc range there are several cleaners, surface primers and accelerators that will maximise the bond performance. This includes surface primers that overcome challenges of “difficult to bond” low surface energy substrates such as polypropylene, polyethylene, PTFE, and thermoplastic rubber materials.
