The Dow Corning EA-5151 ‘Quick in Connect’ (QiC) adhesive from Ellsworth Adhesives Europe has been formulated to accelerate electronic assembly and increase production throughput.
Available as a one-part silicone formulation, the adhesive is applied as a warmed liquid with a plunger-equipped gun or a robotic dispenser. “It cools to a solid viscoelastic material, ensuring primerless adhesion to a broad range of metals and plastics, including substrates that are difficult for many alternative solutions to adhere to,” says the company.
A neutral cure RTV adhesive, EA-5151 has been aligned with transportation electronics market trends to offer a solution to support vehicle efficiency improvement with overall increased safety, enhanced comfort and entertainment. This adhesive has been designed for use in automotive electronics and industrial environments on energy control units, sensors, displays including entertainment, navigation and communications, battery packs and other components requiring attachment, gasketing, lid seal, connector sealing or adhesion.
A unique feature singled out for EA-5151 is its utilisation of silicone technology, which, in turn, achieves instant green strength when dispensing. “This green strength cures to become a strong moisture-cured silicone adhesive and allows the user to handle assembled parts immediately after application. Overall, this minimises waiting time, reduces energy costs and mitigates the need for assembly aids,” adds Ellsworth Adhesives Europe. “Combining as a fast-green strength at room temperature ensures a more efficient alternative to heat-cured adhesives, double-sided tapes and mechanical fasteners is always on hand.”
Additional features claimed include: long open time and pot life, no part warm-up time, service temperatures from -45 to 150°C and the option to be used in conjunction with standard heat assisted dispensing equipment.
