Intertronics launches low-odour, low-bloom light curable CA

Adhesives supplier Intertronics announces Born2Bond Light Lock, a low-odour, low bloom, dual-curing cyanoacrylate adhesive (CA). Designed for a wide range of bonding applications that require fast fixture, coating or surface cure, Light Lock’s dual cure formulation includes both instant (surface) cure and light cure. It is available in high viscosity and gel formulations for bonding, repair, coating or infilling applications.

Light Lock offers typical instant CA adhesive bonding (typically by exposure to surface moisture) for fast interfacial curing, while its UV and visible light reactivity allows rapid curing of exposed fillets or areas, as well as through transparent parts. This means it can solve the typical CA bonding challenge of curing outside of the bond line, says Intertronics.

Without light exposure, Light Lock’s fixture time is around 60 seconds, while with low power visible or long wave UV light it is curable in less than 5 seconds. UV wavelength is not critical - the useful range is from 365 nm to 430 nm and low cost LED-based curing technology is effective.

“Cyanoacrylate adhesives are strong and fast products for interfacial bonds,” explained Ben Swanson, sales manager of Intertronics. “However, they don’t tend to cure quite so well if not between two surfaces. The addition of light curing of any exposed adhesive brings process improvements and decreases the risk of contamination. Light Lock is a simple solution for exposed bond lines, while offering all the benefits of CAs - it is single-part, fast curing and adheres to multiple surfaces.

He continues: “It does not offer the shortcomings of traditional CAs, like blooming, an aesthetically-undesirable residue on the surface of a part - a side effect of CA’s volatility and fast cure,” continued Swanson. “Manufacturers can therefore realise the benefits of both CA and UV technology in one easy-to-use adhesive product.”

Born2Bond Light Lock is available in two viscosities - 600 cps and 30,000 cps - to suit different processes, and in containers of 5g, 20g and 500g. It is ISO 10993-5 and ISO 10993-10 tested and can be evaluated for use in the assembly of medical devices. There are no hazard symbols on the label; it is non irritating, very low odour, and creates dry-to-touch, tack free surfaces when cured.

Common applications in electronics manufacturing include ruggedising, wire tacking, encapsulating, insulation and coating. In medical device manufacturing, it is suitable for plastic and metal bonding, including needle and hearing aid bonding. It has applications in glass-to-metal bonding for jewellery, watches, perfume and liquor bottles.
